Answer:

g( x) = \frac{2}{3}x

Step-by-step explanation:

Given:

Composite Function:

h( x)=f( g( x))

Also,

h( x)=\frac{4}{3}x-1

To find:

g( x )  = ?

Solution:

First of all, let us learn about a composite function.

Composite function f( g( x)) means to write g( x) in place of x in the function f( x).

Let g( x) = y

So, f( g( x)) =  f( y ).

Therefore,

h( x) =f( g( x)) = f( y)

So, f( y) = 2y-1

We have to solve for y in terms of x to find the value of g(x):

\Rightarrow \frac{4}{3}x-1 = 2y-1\\\Rightarrow 2y=\frac{4}{3}x\\\Rightarrow y = \frac{2}{3}x

Hence, the answer is g(  x ) = \frac{2}{3}x.

Checking whether the answer is correct or not:

f( g( x)) = f( \frac{2}{3}x) = 2\times \frac{2}{3}x -1 = \frac{4}{3}x-1

which is h( x).

Hence, our answer g( x ) = \frac{2}{3}x is correct.

The graph of the function P(x) = −0.52x2 + 23x + 92 is shown. The function models the profits, P, in thousands of dollars for a
Liono4ka [1.6K]

Answer:

6.84 ≤ x ≤ 37.39

Step-by-step explanation:

we have

P(x)=-0.5x^2+23x+92 -----> equation A

we know that

The company wants to keep its profits at or above $225,000,

so

PXx)\geq 225 -----> inequality B

Remember that P(x) is in thousands of dollars

Solve the system by graphing

using a graphing tool

The solution is the interval [6.78,39.22]

see the attached figure

therefore

A reasonable constraint for the model is

6.84 ≤ x ≤ 37.39

A dolphin jumped up out of the water and back into the water in a parabolic path. (H) height (t) seconds . H=-8(t-0.5)^2+2 . How
tigry1 [53]

Answer:

4 seconds

Step-by-step explanation:

using the vertex formula of a quadratic,

a(x-h)^{2} + k, where (h,k) is the vertex

h = -8(t-0.5)^{2}+2    h is height and t is time in seconds

the vertex (maximum height) of the dolphin is (h,k) or (0.5, 2)  

Height of 1/2

time of 2 seconds

it will take 2 additional seconds to reach the water again.

this can also be solved using quadratic equation, but since it was already set up in vertex form, i'd use that.

I need to solve the equation 6n + 21 = - 3 - 2n
Kaylis [27]

Answer:

n= -3

Step-by-step explanation:

First, your're going to subtract from both sides

6n + 21 - 2 1= -3 - 2n - 21

Then simplify

6n = -2n - 24

Then add 2n on both sides

6n + 2n = -2n -24 + 2n

Simplify again

8n = -24

Then divide both sides by 8

8n/8 = -24/8

Then simplify and this is your answer

n= -3
