In the given function, the Statement B and C are correct.

According to the statement

We have to find that the y-values of the two functions.

So, For this purpose, we know that the

Function is an expression, rule, or law that defines a relationship between one variable and another variable

From the given information:

The given functions are:

f(x) = -5* +2 and g(x)=-5x² +2

In these functions, we see that the when we solve these functions

Then

The maximum y-value of f(x) approaches 2.

And when we solve the function g(x) then g(x) has the largest possible y-value.

Then the statements in the two functions are the Statement B and C correct.

Using it's concept, the average rate of change of the function on the interval [0,2] is of -1.5.

Before going into the average rate of change, the other items are correct.

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

[tex]r = \frac{f(b) - f(a)}{b - a}[/tex]

For the interval [0,2], we have that:

Hence the rate is:

r = (0 - 3)/(2 - 0) = -1.5.

Simplifying the given polynomial expression is; -(1/4)x³ - (7/2)x² + (214/16)x + (7/2)

We want to simplify the polynomial expression;

((1/2)x + 2)((1/2) - 2x) + ((1/4)x + (7/2))

Let us expand the first bracket to get;

((1/2)x * (1/2) + (2 * (1/2)) - ((1/2)x * 2x) - (2 * 2x))

⇒ (1/4)x + 1 - x² - 4x

⇒ 1 + (15/4)x - x²

Thus, our expression is now;

(1 + (15/4)x - x²)((1/4)x + (7/2))

This can be multiplied out to give;

(1/4)x + (15/16)x - (1/4)x³ + (7/2) + (105/8)x - (7/2)x²

= -(1/4)x³ - (7/2)x² + (107/8)x + (15/16)x + (7/2)

= -(1/4)x³ - (7/2)x² + (214/16)x + (7/2)

Based on the fact that the model has a scale of 1/12, solving the equation of 12x = 86 to determine the tons of the completed sculpture gives 7 tons.

The model is said to have a scale of 1/12 of the original stone landmark which means that if the original famous landmark weighs 86 tons, the tons of the model can be found by the formula:

12x = 86

When solving for x which is the tons of the completed sculpture, the weight would be:

12x = 86

x = 86 / 12

x = 7 tons

In conclusion, the completed sculpture would weigh 7 tons.

The length and width of the rectangle is 23 and 11 cm.

Given, perimeter = 68 cm

A rectangle's perimeter P is determined by the equation P=2l+2w, where l is the rectangle's length and w is its width. In the formula A=lw, where l is the length and w is the width, the area A of a rectangle is determined.

let the width of the rectangle be x.

and length of the rectangle be 12 ₊ x

Formula of the perimeter = 2l ₊ 2w

68 = 2(12 ₊ x) ₊  2x

68 = 2x ₊ 24 ₊ 2x

68 ₋ 24 = 4x

44 = 4x

x = 44/4

x = 11

Hence the width of the rectangle is 11 cm and length:

12 ₊ x

= 12 ₊ 11

= 23 cm

Hence we get the length and width of the rectangle as 23 and 11 cm.

Just plug-in the variable associated with the question.

Step-by-step explanation:
2) w(n) = n² + 5n --> replace the n with 6

4) w(x) = 3x - 1 --> replace the x with -8

6) k(n) = 3n² - 1 --> replace the n with 4

8) g(a) = -2a² + 5 --> replace the a with 9

For example, for number 8, the answer would be -157 if you plug in the value.

g(9) = -2(9)² + 5

Answer:

x - intercept; (80, 0)

y - intercept; (0, ∞)

Step-by-step explanation:

Let Week be w and Amount be A;

We see an inverse proportionality;

[tex]{ \rm{w \: \alpha \: \frac{1}{A } }} \\ \\ { \rm{w = \frac{m}{A} }}[/tex]

m is a constant of proportionality;

When w is 1, A = 68

[tex]{ \rm{ 1 = \frac{m}{68} }} \\ \\ { \rm{m = 68}}[/tex]

Therefore;

[tex]{ \tt{w = \frac{68}{A} + c }} \\ [/tex]

c is a constant;

When w is 0, A is 80

[tex]{ \rm{0 = \frac{68}{80} + c}} \\ \\ { \rm{c = - \frac{17}{20} }}[/tex]

Overall equation:

[tex]{ \rm{y = \frac{68}{x} + \frac{17}{20} }} \\ [/tex]

For x-intercept, y = 0

[tex]{ \rm{ \frac{17}{20} = \frac{68}{x} }} \\ \\ { \rm{x = 80}}[/tex]

For y-intercept, x = 0

In linear equation, S = x2 + 36/x  the surface area S of the box as a function of the length x of one of the sides.

What in mathematics is a linear equation?

Let x = length of the sides of the base, and h = the height.  The volume is given as 9 m3

Volume = area of base * height

9 = x2*h

So 9/x2 = h

The surface area, S, of the box is:

S = (Area of Base) + 4*(Area of a Vertical Side)

S = x2 + 4 * (xh)

Substitute 5/x2 in place of h:

S = x2 + 4 * x * (9/x2)

S = x2 + 36/x
