Line a is parallel to line b and line c is parallel to line d, using the diagram what can be said about angle 7 and 12

**Answer:**

C

**Step-by-step explanation:**

Angle 7 is congruent to angle 5 by the corresponding angles theorem, and angles 5 and 12 are supplementary because they are consecutive interior angles.

Thus, angles 7 and 12 are supplementary.

Bonus: Write the equation of a line in slope intercept form that is parallelto y=4/3x-7 and contains the point (5,-8)

The given equation is

[tex]y=\frac{4}{3}x-7[/tex]The slope of the given line is 4/3 because it's the coefficient of *x*.

Now, the new line has a slope of 4/3 too because parallel lines have equal slopes.

We know that the new line passes through the point (5, -8). Let's use the point-slope formula to find the equation.

[tex]y-y_1=m(x-x_1)[/tex]Replacing the points and the slope, we have.

[tex]\begin{gathered} y-(-8)=\frac{4}{3}(x-5) \\ y+8=\frac{4}{3}x-\frac{20}{3} \\ y=\frac{4}{3}x-\frac{20}{3}-8 \\ y=\frac{4}{3}x+\frac{-20-24}{3} \\ y=\frac{4}{3}x-\frac{44}{3} \end{gathered}[/tex]Therefore, the equation of the new line is y = (4/3)x - (44/3).Given f(x) = 2x² + 2x + k, and the remainder when f(x) is divided by x - 1 is

--------------------

2 -5 k+35 Rem is 32;

Let 32 = k + 5 and solve for k:

k = -3.

Let's check that. Is k correct?

Then -7 / 2 9 -3

2 -5 -3+35 = 32

Since the rem is 32, we are correct; k = -3.

The width of a Rectangle is 3.6 inches and the perimeter is 72 inches. What is the length of the rectangle?

We know that

• The width of the rectangle is 3.6 inches.

,• The perimeter is 72 inches.

The perimeter formula for a rectangle is

[tex]P=2(w+l)[/tex]Where P = 72, w = 3.6, and we have to solve for l.

[tex]\begin{gathered} 72=2(3.6+l) \\ \frac{72}{2}=3.6+l \\ 36=3.6+l \\ l=36-3.6 \\ l=32.4 \end{gathered}[/tex]Therefore, the length of the rectangle is 32.4 inches.The graph shows the mass of the bucket containing liquid depends on the volume of liquid in the bucket. Use the graph to find the range of the function.

The **graph **shows that the **range **of the function is **0.9 ≤ M ≤ ∞**.

A linear function can be represented by a **line**. The **standard form** for this equation is: **y=mx+b** , for example, y=5x+8.

All functions present their **domain **and **range**. The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. While the domain is related to the values of x, the range is related to the possible values of y that the function can have.

From the graph it is possible to see that: the function is a **linear function**, the values of the **coordinate x** are represented by the **volume **(liters) while the values of the **coordinate y **are represented by the **mass **(kg).

The question asks for the range of the function. Therefore, you should indicate the possible values of y that the function can have.

For this, you should analyze the axis-y. See that for x=0, the graph shows y =0.9. Therefore, the function starts for values of y >= 0.9 kg. It is possible to verify that when the volume increases, the mass also increases. With this information, you can find that the range is 0.9 ≤ M ≤ ∞.

Input x Output y3. -56. -49. -3What is a equation

We are to determine the equation of line by interpreting tabulated results between an independent variable ( x ) and a dependent variable ( y ).

A function is usually expressed as follows:

[tex]y\text{ = f ( x )}[/tex]The above notation gives us the output ( y ) which is a function of input variable ( x ). This means that whatever relationship these two variables have the value of output ( y ) is related to the imput variable ( x ).

We are given a table/list of values of output ( y ) corresponding to each value of input variable ( x ) as follows:

**Input ( x ) ** **Output ( y )**

3 -5

6 -4

9 -3

There are a series of steps that we must take to arrive at the equation that relates two variables.

**Step 1:** Determine the type of relationship between two variables by intuition

The first step in the process is the hardest of all. We have to critically analyze each input value ( x ) and its corresponding output value ( y ) with successive pair of values.

There are many types of relationships possible ( polynomial order, exponential, logarithmic, trigonometric, radical, etc .. ).

We can conjure up a way by comparing outputs of successive values to determine the type of relationship possible.

So looking at the first value:

[tex]y\text{ = f ( 3 ) = -5}[/tex]The successive value:

[tex]y\text{ = f ( 6 ) = -4}[/tex]The next successive value:

[tex]y\text{ = f ( 9 ) = -3}[/tex]Here if scrutinize between each successive value of input variable ( x ) we see that there is a "3 unit step-up" in each pair of values i.e ( 3 -> 6 -> 9 ).

Next we compare each output values ( y ) for successive pairs. We see that with every step increase of 3 units in ( x ) value there is an increase of ( 1 ) unit in output value i.e ( -5 -> -4 -> -3 ).

**Conclusion:** Combing the result of above analysis we see that with each 3 step increase in input value ( x ) there is an increase in output value ( y ) by 1 unit.

This gives us the idea that the two variables are linearly related to one another.

Therefore, the type of relationship is:

[tex]\text{straight line }\text{ }[/tex]**Step 2:** Recall the equation for the type of relationship between two vairbales x and y

Once we have determined the type of relationship between two variables. We will have to resort to our equation bank and pluck out the corresponding equation that expresses a **LINEAR** relationship i.e equation of a straight line.

The slope-intercept form of a straight line is:

[tex]y\text{ = m}\cdot x\text{ + c}[/tex]**Step 3:** Determine the complete equation of function by defining the arbitrary constants.

The above equation is valid for all straight lines that express a linear relationship. However, we seek to find a unique straight line for the given set of points.

Every unique straight line equation would have either of the constants different. The constants defined in a striaght line equation are:

[tex]\begin{gathered} m\colon\text{ The slope( gradient ) of the line} \\ c\colon\text{ The y-intercept} \end{gathered}[/tex]To determine these constants we will use the given pairs of coordinates of input and output variables, x and y respectively.

To determine the slope (m) of an equation:

[tex]m\text{ = }\frac{y_2-y_1}{x_2-x_1}[/tex]The above expression relates the change in output value ( y ) with respect to change in input variable ( x ).

To determine the constant ( m ) we will use the conclusion from **Step 1**:

"**3 step increase in input of ( x ) value there is an increase in output value ( y ) by 1 unit.**"

Therefore,

[tex]m\text{ = }\frac{+1}{+3}\text{ = }\frac{1}{3}[/tex]To determine the value of y-intercept ( c ). We will plug in the value of ( m ) into the general equation of a straight line written in step 2:

[tex]y\text{ = }\frac{1}{3}x\text{ + c}[/tex]Now, we will use **any pair** of input and output value.

Substitute the pair of values into the derived equation expressed above and solve for constant ( c ):

[tex]\begin{gathered} -5\text{ = }\frac{1}{3}\cdot(3)\text{ + c} \\ -5\text{ = 1 + c} \\ c\text{ = -6} \end{gathered}[/tex]**Note: **The above step implies that following equation must satisfy each and every data pair of point given to us ( table ). Or each and every value must lie on the line. For that each value must satisfy the equation of line.

**Step 4**: Write the complete equation of the relationship

Once we have evaluated the values of equation defining constants ( m and c ). We can simply plug in the values into the general equation relationship ( **Linear - slope intercept form** ) as follows:

Therefore, the equation for the set of values given to us is:

[tex]\begin{gathered} \textcolor{#FF7968}{y}\text{\textcolor{#FF7968}{ = }}\textcolor{#FF7968}{\frac{1}{3}\cdot x}\text{\textcolor{#FF7968}{ - 6}} \\ OR \\ y\text{ = }\frac{x\text{ - 18}}{3} \\ \textcolor{#FF7968}{3y}\text{\textcolor{#FF7968}{ = x - 18}} \end{gathered}[/tex]Find in the exact simplified form of an exact expression for the sum of the first n terms of the following series 1+11+111+1111+11111+.... Binary notation is used to represent numbers on a computer. For example, the number 1111 in base two represents 1(2)^3 + 1(2)^2 +1(2)^1+1, or 15 in base ten. (i) Why is the sum above an example of a geometric series? (ii) Which number in base ten is represented by 11 111 111 111 111 111 111 in base two? Explain your reasoning.

**Step-by-step explanation:**

so, I understand, the given series is written in binary form.

a1 = 1 = 1×2⁰ = 1

a2 = 11 = 1×2¹ + 1× 2⁰ = 3

a3 = 111 = 1×2² + 1×2¹ + 1×2⁰ = 7

a4 = 1111 = 1×2³ + 1×2² + 1×2¹ + 1×2⁰ = 15

a5 = 11111 = 1×2⁴ + 1×2³ + 1×2² + 1×2¹ + 1×2⁰ = 31

...

we see, that

an = 2×(an-1) + 1

a1 = 1

a2 = 2×a1 + 1

a3 = 2×a2 + 1 = 2×(2×a1 + 1) + 1 = 4×a1 + 2 + 1

a4 = 2×a3 + 1 = 2×(2×a2 + 1) = 2×(2×(2×a1 + 1) + 1) + 1 =

= 8×a1 + 2×2 + 2 + 1 = 8×a1 + 7

...

an = (2^(n-1))×a1 + an-1

because

an = 2×(an-1) + 1,

an-1 = (2^(n-1))×a1 - 1

therefore,

an = 2×(2^(n-1))×a1 - 1 = (2^n)×a1 - 1

the sequence of the sums of the first n elements

s1 = a1 = 1

s2 = a1 + a2 = 1 + 3 = 4

s3 = a1 + a2 + a3 = 7 + 3 + 1 = 11

s4 = a1 + a2 + a3 + a4 = 15 + 7 + 3 + 1 = 26

...

(i)

it is NOT a geometric sequence.

for a geometric sequence

an/an-1 = r, and r must be a constant ratio for any n.

but

7/3 = 2.333333...

15/7 = 2.142857143...

these are different, so, the sequence itself is not geometric.

neither is the sequence of the sums of the series. because

11/4 = 2.75

26/11 = 2.363636363...

are different.

1, 2, 4, 8, 16, 32, ... is a geometric sequence (constant r = 2).

but not

1, 3, 7, 15, 31, ...

(ii)

11 111 111 111 111 111 111 in base 2.

the utmost right position is the 2⁰ position. every position further to the left multiples the position value by 2. it is the same process as for numbers in base 10 (just there every position value is multiplied by 10).

we have 6×3 + 2×1 positions = 20 positions.

so, the position values go from 2⁰ to 2¹⁹.

as per the formula for "an" up there, we get

a20 = (2²⁰)×a1 - 1 = 1,048,576 - 1 = 1,048,575

Give three value to x such that |xl= -x.

To simplify the expressions you have to combine the like terms.

This means that you'll solve the operations between the terms that have the same variables, for example x + 2x=3x

Or the terms that have no variables and are only numbers, for example 4+5=9

a. The expression is

[tex]4x+3x[/tex]Both terms have the same variable "x", so you can add them together. To do so, add the coefficients, i.e. the numbers that are being multiplied by x

[tex]4x+3x=(4+3)x=7x[/tex]And you get that the simplified expression is **7x**

b. The expression is

[tex]3x+5x-1[/tex]In this expression you have two types of terms, the x-related terms and one constant. In this case you have to solve the operation for the x-related terms together and leave the constant as it is

[tex](3x+5x)-1=(3+5)x-1=8x-1[/tex]The simplified expression is **8x-1**

**Answer**

**Option B is correct.**

**Angle Y = 68º**

**Explanation**

Similar triangles have the same set of angles in them.

All the corresponding angles are equal to each other.

So, if **triangle ABC **is similar to **triangle XYZ**

**Angle A = Angle X**

**Angle B = Angle Y**

**Angle C = Angle Z**

The order in which they are named determines the angles that are corresponding to each other.

So, if **Angle B = 68º**

**Angle Y = Angle B = 68º**

**Angles** are given below.

When two straight lines or rays intersect at a single endpoint, an **angle** is created. The vertex of an angle is the location where two points come together. The Latin word "angulus ," which means "corner," is where the term "angle" originates. When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar.

The expression for the volume of the box is:

[tex]v(x)=x(11-2x)(17-2x)[/tex]Mathematically, there is no restriction for the values of x, but phisically we know that x is a length and has a positive value, so x>0.

Also, we know that x can not be largest than half of the width, that is the smallest dimension of the piece of paper.

As the width is 11, we then know that x is smaller than 11/2=5.5.

In conclusion, the domain for x is:

[tex]0To calculate the maximum volume for the box we have to derive the volume function and equal to zero:[tex]\begin{gathered} v(x)=x(11-2x)(17-2x) \\ v(x)=x(11\cdot17-11\cdot2x-2x\cdot17+4x^2) \\ v(x)=x(4x^2-56x+187) \\ v(x)=4x^3-56x^2+187x \end{gathered}[/tex][tex]\begin{gathered} \frac{dv}{dx}=4(3x^2)-56(2x)+187(1)=0 \\ 12x^2-112x+187=0 \\ x=\frac{-(-112)\pm\sqrt[]{(-112)^2-4\cdot12\cdot187}}{2\cdot12} \\ x=\frac{112\pm\sqrt[]{12544-8976}}{24} \\ x=\frac{112\pm\sqrt[]{3568}}{24} \\ x=\frac{112}{24}\pm\frac{59.73}{24} \\ x=4.67\pm2.49 \\ x_1=4.67-2.49=2.18\approx2 \\ x_2=4.67+2.49=7.16\approx7 \end{gathered}[/tex]The solutions are x=2 and x=7 approximately.

Because of our domain definition, we know that x=7 is not a valid solution, so the value of x that maximizes the volume is x=2.

The volume for x=0 is 0. Then, it will increase its value until x=2, where it reaches the maximum volume. From x=2 to x=5.5, the volume decrease until reaching v=0 at x=6.5.

**Answer:**

**Domain: 0**

**Value of x that maximizes the volume: x=2.**

**From x=0 to x=2 the volume of the box increases.**

Find the area of ABC with vertices A(3,-6), B(5,-6), and C(7,–9).

**Area** of a **triangle** ABC with the given vertices is 3 square units.

Given that, the vertices of a triangle ABC, A(3,-6), B(5,-6), and C(7,–9).

What is the area of triangle formula in coordinate geometry?In Geometry, a **triangle** is a three-sided polygon that has three edges and three vertices. The **area** of the **triangle** is the **space** covered by the triangle in a two-dimensional **plane**.

Area of a triangle = [tex]\frac{1}{2} ( |x_1(y_2 - y_3) + x_2(y_3 - y_1) + x_3(y_1 - y_2)|)[/tex]

Here, (x1, y1) = A(3,-6), (x2, y2) = B(5,-6), and (x3, y3) = C(7,–9)

Now, the **area** of a **triangle** = 1/2 (|3(-6+9)+5(-9+6)+7(-6+6)|)

= 1/2 (|3(3)+5(-3)+7(0)|)

= 1/2 (|(9-15)|)

= 1/2 × 6

= 3 square units

Therefore, **area** of a **triangle** ABC with the given vertices is 3 square units.

The **values **are as:

a) f(g(x)) = √(x+ 9)

b) (gf)(x)= √x +9

What is function?The core concept of mathematics' calculus is functions. The unique **varieties **of **relations **are the **functions**. In mathematics, a **function **is represented as a **rule **that produces a **distinct** **result **for each **input** x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the **values **that the function may **input **while it is defined is known as the **domain**. The **whole set **of **values **that the function's **output** can produce is referred to as the **range**. The set of values that might be a function's outputs is known as the co-domain.

Given:

f(x)=√x, g(x)=x+9

a) (fg)(x)=

f(g(x)) = f( x+9)

= √(x+ 9)

Now, **domain **is all the **input **values

i.e., x=2, 4, 7

f(g(2)) = √(2+ 9)

= √11

and, f(g(4)) = √(4+ 9)

= √13

and, f(g(7)) = √(7 + 9)

= √16

= 4

b) (gf)(x)= g(f(x))

= g(√x)

= √x +9

Now, **domain** is all the **input **values

i.e., x=2, 4, 7

f(g(2)) = √2+ 9

and, f(g(4)) = √(4+ 9)

= 2+9

= 11

and, f(g(7)) = √7 + 9

If f (x) = x

2 − 2 x , g (x) = x − 2

1) prove that : f(2) = g(2)

2) If g (K) = 7 , find : the value of k

The value of** k **is **9 **for the **function g.**

To solve this problem we should have a brief concept of** algebraic functions.**

To solve this problem we have to follow a few steps.

Here **f is a function of x** and the relation with the function denotes as **x²-2x**. Also,** g is a function of x** and the relation with the function denotes as** x− 2.**

If we put, **x = 2 **on f(x) = x²-2x. We can write, **f(2)** = 2²-2.2 = 4 - 4 =** 0**.

If we put,** x = 2** on g (x) = x − 2. We can write, ** g(2) **= x− 2= 2- 2 = **0**.

Hence, we can conclude that ** f(2) = g(2) = 0. ** ( proved)

Here, g(k) = 7. So,** x = k** in this relation.

We have to put x= k on g(x) = x− 2 ; now we can write, **g (k) = k− 2.**

g (k) = k− 2 = 7 as per the question. Therefore** **k = 7 + 2 = 9

The value of k is 9.
