Answer:

f(x) > h(x) > g(x)

Step-by-step explanation:

For the average rate of change of a function between x = a and x = b,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

From the table given,

Average rate of change of function 'f' between x = 1 and x = 3,

Average rate of change = [tex]\frac{f(3)-f(1)}{3-1}[/tex]

                                        = [tex]\frac{15-7}{3-1}[/tex]

                                        = 4

For the function 'g',

g(x) = 2x² - 18x

Average rate of change = [tex]\frac{g(3)-g(1)}{3-1}[/tex]

g(3) = 2(3)²- 18(3)

      = 18 - 54

      = -36

g(1) = 2(1)² - 18(1)

      = 2 - 18

      = -16

Therefore average rate of change = [tex]\frac{-36+16}{3-1}[/tex]

                                                         = -10

From the graph attached,

Average rate of change of the graph between x = 1 and x = 3,

Average rate of change = [tex]\frac{h(3)-h(1)}{3-1}[/tex]

h(3) = 7.5 [Although the graph is not clear]

h(1) = 2

Average rate of change = [tex]\frac{7.5-2}{3-1}[/tex]

                                        = 2.75

Therefore, order of rate of change (from greatest to the least) for the given functions will be,

f(x) > h(x) > g(x)

The sine function is:

f(x) = -2*sin(x/2) + 3.

So you got it almost correctly, you only forgot to apply the reflection.

We start with the general sine function:

[tex]a*g(w*x + p) +m[/tex]

where g(x) = sin(x)

f(0) = 2*sin(w*0 + p) + 3 = 3

      = 2*sin(p) + 3 = 3

Then we must have p = 0, so there is no phase shift.

We also know that we have a reflection over the x-axis of the parent sine function, we would actually have:

f(x) = 2*-sin(wx) + 3

Finally, to get the value of k we know that the period of the general sine function is 2*pi, while here is 4*pi, then we must have w = 1/2 to get the correspondent correction, so the function is:

f(x) = -2*sin(x/2) + 3.

This is almost the same thing that you got in the graph, where you only forgot to apply the reflection over the x-axis of the parent function.

Answer:

4. A​ post-lunch nap decreases the amount of time it takes males to sprint 20 meters.

Step-by-step explanation:

This question wants us to state the claim and the hypothesis.

This researchers claim can be found in the first sentence of this question.

Claim: post lunch nap decreases the time it takes to run for 20 meters.

The correct answer option for the claim is the 4th answer option. And it means that sleeping after lunch reduces the time it takes males to run in a 20m race.

B. Hypothesis

Answer:

54 = 6b

Step-by-step explanation:

Sandra rode her bike 54 miles in one day.

She rode 6 times the  number of miles Caleb rode his bike.

Let Caleb rode b miles. It means,

54 = 6b

We can also find b as follows :

b = (54/6)

b = 9 miles

Hence, the required equation is "54 = 6b".

Answer:

It represents growth, and the percentage rate of increase is of 8%

Step-by-step explanation:

Exponential equation:

An exponential equation has the following format:

[tex]A(t) = A(0)(1 + r)^t[/tex]

In which A(0) is the initial amount and r is the rate of change, as a decimal. If positive, it is growth, if negative, it is decay.

In this question:

[tex]y = 21(1.08)^x[/tex]

So

[tex]1 + r = 1.08[/tex]

[tex]r = 0.08[/tex]

Since r is positive, it represents growth, and the percentage rate of increase is of 0.08*100% = 8%

Step-by-step explanation:

The dimension of the box is 12 by 7 by 8

The volume of the box = lwh

Given the following

l = w

w = w - 5

h = w - 4

Hence;

w(w-5)(w-4) = 56w

Expand to have

(w^2-5w)(w-4) = 56w
w^3 - 4w^2 - 5w^2 + 20w = 56w
w^3 -9w^2 - 36w = 0

Factorize to get the value of w;

w(w^2-9w-36)=0

w^2 - 12w + 3w - 36 = 0

w(w-12) + 3(w-12)= 0
w = -3 and 12

Hence the dimension of the box is 12 by 7 by 8

I'm unsure what you want me to do here, so I drew a graph (using Desmos) and the slope.

The slope is given, 5/3. The slope-intercept equation is usually y = mx + b -- m being the slope and b being the y-intercept.

Hi!

Let's check if the equation that we're going to work with is in slope-intercept form.

Remember, the slope-intercept formula is:

Answer:

The distance between these two points is of 5 units.

Step-by-step explanation:

Distance between two points:

Suppose that we have two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]. The distance between them is given by:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

In this question:

Distance between  (-7,-1) and (-4,3). So

[tex]D = \sqrt{(-4-(-7))^2+(3-(-1))^2} = \sqrt{3^2+4^2} = \sqrt{25} = 5[/tex]

The distance between these two points is of 5 units.
