Answer:

For f(x) =  x^2 - 2x + 1, the inverse is g(x) = √x + 1

For f(x) = 2 - 5*x the inverse is g(x) = (2 - x)/5

For f(x) =  5*(x - 2) the inverse is g(x) = x*(1/5) + 2

for f(x) = (x - 2)^2 - 1 the inverse is g(x) = √(x + 1) + 2

Step-by-step explanation:

If we have two functions f(x) and g(x) such that these functions are inverse, then we have:

f( g(x)) = x

and

g( f(x)) = x

Let's start with the function:

f(x) = x^2 - 2x + 1

Notice that we can rewrite this as:

f(x) = x^2 - 2*x + 1 = (x - 1)^2

Because this is a quadratic function, the inverse function needs to have a square root, then the inverse function can be the third or fourth one.

Let's try with the last one:

g(x) = √x + 1

Then:

f( g(x)) = ( √x + 1 - 1)^2 = (√x )^2 = x

g( f(x)) = √(x - 1)^2 + 1 = (x - 1) + 1 = x

Then for the function:

f(x) = x^2 - 2x + 1, the inverse is: g(x) = √x + 1

Now let's find the inverse for the second function:

f(x) = 2 - 5*x

The inverse of this function will be also a linear function, and the slope of the inverse will be the inverse of this slope, then the inverse may be the first or second options.

Let's try with:

g(x) = (1/5)*x - 2

Then:

f( g(x) ) = 2 - 5*((1/5)*x - 2) = 2 - x + 10

Then this g(x) is not the inverse of the function.

Let's try with g(x) = (2 - x)/5

Then:

f( g(x)) = 2 - 5*(2 - x)/5 = 2 - 2 + x = x

g( f(x)) =  (2 - 2 - 5*x)/5 = 5*x/5 = x

For the function f(x) = 5*(x - 2)

The inverse should be the remaining linear function:

g(x) = x*(1/5) + 2

Then:

f( g(x)) = 5*(x*(1/5) + 2 - 2) = 5*x*(1/5) = x

g( f(x)) = (5*(x - 2) )*(1/5) + 2 = (x - 2) +2 = x

For the last function, f(x) = (x - 2)^2 - 1

The inverse function will be:

g(x) = √(x + 1) + 2

The compositions are:

f( g(x)) = (√(x + 1) + 2 - 2)^2 - 1 = (√(x + 1))^2 - 1 = (x + 1) - 1 = x

g(f(x)) = √((x - 2)^2 - 1 + 1) + 2 = √((x - 2)^2 + 2 = x

PLATO ANSWER

Step-by-step explanation:

Answer:

option B. G

Step-by-step explanation:

Let

y ---->ounces of orange juice

x --->  ounces of pineapple juice

we know that

The ratio of orange juice to pineapple juice is equal to

substitute the given values

simplify

Verify each graph

Remember that the formula of slope is "rise over run", where the "rise" (means change in y, up or down) and the "run" (means change in x, left or right)

we have

that means

5 ounces of orange juice per 3 ounces of pineapple juice

Graph F

The slope is

Graph G

The slope is

Graph H

The slope is

Graph J

The slope is

The value of 2 is the value closest to 1.67

therefore

The graph that has a slope that best represents the ratio of orange juice to pineapple juice is Graph GStep-by-step explanation:

The ratio of orange juice to pineapple juice in this bottle is 5: 3, so the correct option is G.

Given that a bottle contains 30 fluid ounces of orange juice and 18 fluid ounces of pineapple juice, to determine which graph has a slope that best represents the ratio of orange juice to pineapple juice in this bottle, the following calculation must be performed:

Therefore, the ratio of orange juice to pineapple juice in this bottle is 5: 3, so the correct option is G.

Question 2 = True

I don't know the first question, the test wouldn't tell me:/

Angle C, Angle Z, Angle A, and Angle W are all angles whose cosine equals 35 and the statement that Sin B is greater than Sin Y is false.

The two triangles are said to be similar that have the same proportion of sides and angles.

Corresponding sides are in the same ratio.

a/p = b/q = c/r

In triangle ABC

AB = 5, AC = 3, BC = 4

Cos A = base/ hypotenuse

          = 3/5

Cos B = base/ hypotenuse

          = 4/5

Cos C = base/ hypotenuse

          = 3/5

In triangle WYZ

Cos W = base/ hypotenuse

           =  3/5

Cos Z = base/ hypotenuse

          = 4/5

Hence, Angle C, Angle Z, Angle A, and Angle W are all angles whose cosine equals 35.

In triangle WYZ

WY = 13

In triangle ABC

CB = 24, AC = 10

Sin B = Perpendicular/ hypotenuse

         = 10/26

Sin Y = Perpendicular/ hypotenuse

        = 5/13

Since both angles are equal also they are similar to each other.

Therefore, the statement that Sin B is greater than Sin Y is false.

Answer:

The maximum height of the projectile is 90 ft

Step-by-step explanation:

Here, we want to get the maximum height reached by the projectile

The answer here will be the y-coordinate value of the vertex form of the given equation

so firstly, we have to write the equation in the vertex form

We have this as;

y = -16t^2 + 64t + 26

That will be;

y = a(x-h)^2 + k

y = -16(x-2)^2 + 90

where the vertex of the equation is;

(-h,k)

K

in this case is 90 and thus, that is the maximum height of the projectile

Step-by-step explanation:

Given

[tex]ABD = 0.18x +67[/tex]

[tex]CBD = 0.07x + 48[/tex]

Required

Find x

The question is incomplete as the relationship between ABD and CBD is not stated.

Assume ABD = CBD

The solution is:

[tex]0.18x + 67 = 0.07x + 48[/tex]

Collect like terms

[tex]0.18x - 0.07x= - 67 + 48[/tex]

[tex]0.11x= -19[/tex]

Solve for x

[tex]x = -\frac{19}{0.11}[/tex]

[tex]x = -172.72[/tex]

Assume ABD and CBD are supplementary

The solution is:

[tex]ABD + CBD=180[/tex]

[tex]0.18x + 67 + 0.07x + 48 = 180[/tex]

Collect like terms

[tex]0.18x + 0.07x = - 48 - 67 + 180[/tex]

[tex]0.25x = 65[/tex]

Solve for x

[tex]x = \frac{65}{0.25}[/tex]

[tex]x = 260[/tex]

Assume ABD and CBD are complementary

The solution is:

[tex]ABD + CBD=90[/tex]

[tex]0.18x + 67 + 0.07x + 48 = 90[/tex]

Collect like terms

[tex]0.18x + 0.07x = - 48 - 67 + 90[/tex]

[tex]0.25x = -25[/tex]

Solve for x

[tex]x = \frac{-25}{0.25}[/tex]

The quantity of concrete used to make the patio is 1.44 m³

Since the solid concrete patio is a right rectangular prism, to find the amount of concrete used in making the patio, we find its volume.

So, the volume of the patio, V = lbh where l = length of patio = 4.5 m, b = width of patio = 3.2 m and h = thickness of patio = 0.1 m

So, V = 4.5 m × 3.2 m × 0.1 m = 1.44 m³

The quantity of concrete used to make the patio equals the volume of the patio.

So, the quantity of concrete used to make the patio is 1.44 m³
