which of the following options result in a graph that shows expoential decay

The option that results in a **graph** that shows **exponential decay** is Option(b) f(x) = 3(0.7)ˣ.

According to the question, we have to determine the** function** that results in a **graph **that shows exponential decay.

The function will show an exponential decay if the value of b was less than 1 and greater than 0.

As we can notice in the second option, f(x) = 3(0.7)ˣ, where b is equal to 0.7 which is less than one.

So, f(x) = 3(0.7)ˣ shows exponential decay.

**Step-by-step explanation:**

we sadly need to do all the multiplications for the whole polynomial in standard form.

the other 3 things we get out of the given form :

we multiply 3 terms, each in x. the result will be x³.

so, we have the 3rd degree.

the leading coefficient is 1, as for the x³ term we get x×x×x = x³. no other number is involved.

the constant term is the extreme on the other end. it is 4×2×1 = 8.

so, now for the full multiplications, that should also show you, why I could make the conclusions above.

(x+4)(x-2)(x+1)

we do this by multiplying first 2 terms with each other, and then we multiply that result by the third term.

remember, we need to multiply every item of one term with every item in the other term.

(x+4)(x-2) = x² -2x + 4x - 8 = x² + 2x - 8

now

(x² + 2x - 8)(x+1) = x³ + x² + 2x² + 2x - 8x - 8 =

= x³ + 3x² - 6x - 8

so, that is already the standard form

f(x) = x³ + 3x² - 6x - 8

In AJKL, JL is extended through point L to point M,

m/JKL = (3x – 16)°, m/LJK = (2x + 15)°, and

m/KLM = (8x – 19)°. Find m/LJK.

The value of x is 6 and the measure of **angle** LJK is 27°.

According to the triangle's "**angle sum property**," a triangle's interior angles add up to 180°.

We have the measure of the following **angles**,

m∠JKL = ( 3x - 16 )°

m∠LJK = ( 2x + 15 )°

m∠KLM = ( 8x - 19)°

In ΔJKL, JL is extended through point L to point M.

At point L, the measure of **angle** JLK will be as,

m∠KLM + m∠JLK = 180°

m∠JLK = 180° - m∠KLM

m∠JLK = 180° - ( 8x - 19)°

m∠JLK = ( 199 - 8x )°

Now,

In triangle JKL,

By **angle sum property**:

m∠JKL + m∠LJK + m∠JLK = 180°

(3x – 16)° + (2x + 15)° + ( 199 - 8x )° = 180°

- 3x + 198 = 180

- 3x = - 18

x = 6°

Therefore,

m∠LJK = ( 2x + 15 )°

m∠LJK = ( 2(6) + 15 )°

m∠LJK = ( 12 + 15 )°

m∠LJK = 27°

The measure of **angle** LJK is 27°.

Between 10 P.M. and 7:45 A.M., the water level in a swimming pool decreased by

3/8 in. Assuming that the water level decreased at a constant rate, how much did the water level drop each hour?

Please help asap

The **water level drop **each hour by 0.0384 inch

Firstly, the **deacrease in water level** is takes as per the question

Decrease = 3/8 inches

Decrease=0.375 inches

Then the time interval is calculated

From 10 pm to 7:45 hours will be 9.45 hours

Time interval= (9 + 45/60) hours

Time interval=9.75 hours

Now, the drop in water level per hour is determined, to do so, total water level decreased is divided by the time taken to decrease that water level

that is 0.375/9.75 inches/hour

= 0.03846 inches/hour

Therefore, if between 10 P.M. and 7:45 A.M., the water level in a swimming pool decreased by 3/8 inches and the **water level decreased** at a constant rate, the water level drop each hour is 0.03846

Determine the slope of the function as a unit rate for the linear situation. y = − 4 4/5x + 13 1/2

The slope of the function as a unit rate for the **linear situation**. y = [tex]-4\frac{4}{5}[/tex]x + [tex]13\frac{1}{2}[/tex] can be viewed as [tex]-4\frac{4}{5}[/tex] by taking the **derivative **of the first term of the equation.

The slope m=y/x of a straight-line y=mx+b quantifies the change in y for every unit change in x. This can also be interpreted as a kind of measure of "sensitivity''.

Finding the slope of a function is like finding the rate at which the value of y (the **dependent variable**) changes in relation to x is what this method entails (**independent variable**).

To find the slope of a line that is given with the equation of the line, first you have to write the equation of the line in a **slope-intercept** form.

Then use **inverse operations** in order to solve for y so that it is written as y=mx+b. Thereafter you can easily spot the slope since the slope is the **coefficient **of the x variable, or in other words, the number in front of x.

A **function **is simply a relationship that maps one **input **to one **output**..

Given the data in the question;

f( x ) = x² + 3xg( x ) = 2x - 1f( g(-2) ) = ?First, set up the **composite **result **function **f( g(x) )

f( x ) = x² + 3x

f( g(x) ) = f( 2x - 1 ) = ( 2x - 1 )² + 3( 2x - 1 )

f( g(x) ) = ( 2x - 1 )² + 3( 2x - 1 )

Simplify

f( g(x) ) = ( 2x - 1 )( 2x - 1 ) + 3( 2x - 1 )

f( g(x) ) = 2x( 2x - 1 ) -1(2x - 1 ) + 3( 2x - 1 )

f( g(x) ) = ( 4x² - 2x - 2x + 1 ) + 3( 2x - 1 )

f( g(x) ) = ( 4x² - 4x + 1 ) + 6x - 3

f( g(x) ) = 4x² - 4x + 1 - 6x - 3

f( g(x) ) = 4x² - 4x + 6x + 1 - 3

f( g(x) ) = 4x² + 2x - 2

Now, replace all the occurrence of x with -2 in the **function** and simplify.

f( g(-2) ) = 4(-2)² + 2(-2) - 2

f( g(-2) ) = 4×4 - 4 - 2
