To solve this problem, we have to understand and establish some basic mathematical facts on a cone.

The answer to this question are option b and c only.

This is a solid figure that has the base of a circle and the top is made up round triangle.

The formula of volume of a cone is given as

[tex]v = \frac{1}{3}\pi r^2 h[/tex]

where;

In the given question, the first fact given is if the radius doubles the diameter and that false.

[tex]diameter = 2 * radius[/tex]

If we have the value of the the radius, we can calculated the base area using area of a circle

[tex]area = \pi r^2[/tex]

The volume of a cone is actually one-third the volume of a cylinder

we can only calculate the volume of the cone is we have the value of the height of the cone.

Concepts

The formula to find the slope of a line given two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. These points represent the x- and y-coordinates of the points.

Application

To find the slope of these points, we need to take two points and use the aforementioned formula. Let's take (0, 8), and (1, 16).

Solution

Therefore, the slope is 8.

Answer:

slope = 8

Step-by-step explanation:

Take 2 points from the given table:

[tex]\textsf{let}\:(x_1,y_1)=(0,8)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(-1,0)[/tex]

Use the slope formula to find the slope:

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{0-8}{-1-0}=\dfrac{-8}{-1}=8[/tex]

Answer:

y = - 3x² + 6x + 9

Step-by-step explanation:

given the zeros of a parabola x = a , x = b , then the factors are

(x - a) , (x - b)

here the zeros are x = - 1 and x = 3 , then

factors are (x + 1) and (x - 3)

the equation of the parabola is then the product of the factors, that is

y = a(x + 1)(x - 3) ← a is a multiplier

to find a substitute the point (0, 9 ) into the equation

9 = a(0 + 1)(0 - 3) = a(1)(- 3) = - 3a ( divide both sides by - 3 )

- 3 = a

then equation is

y = - 3(x + 1)(x - 3) ← expand factors using FOIL

  = - 3(x² - 2x - 3) ← distribute parenthesis by - 3

y = - 3x² + 6x + 9

Absolute value of any number is positive. so the absolute value of (-35) is 35.

Step-by-step explanation:

The average rate of change of the function over the interval x = 0 to x = 4 is: 61/400.

Average rate of change = f(b) - f(a) / b - a

Given the function, f(x) = 2x - 1 / 3x + 5.

a = 0, f(a) = 2x - 1 / 3x + 5 = 2(0) - 1 / 3(0) + 5 = -1/5

b = 4, f(b) = 2x - 1 / 3x + 5 = 2(4) - 1 / 3(4) + 5 = 7/17

Average rate of change = 7/17 - (-1/5) / 4 - 0 = 61/400

Answer:

8

Step-by-step explanation:

Re-write the equation:

h(x) = x² * 2 - x² -7x

If X is equal to -8, then we can re-write the equation as:
h(-8) = (-8)² * 2 - (-8)² - 7(-8)

Following P.E.M.D.A.S. we must first solve for the exponents:

h(-8) = (64) * 2 - (64) - 7(-8)

Then we need to solve the multiplication.

h(-8) = (128) - (64) - (-56)

Now, we solve for the addition/subraction.

h(-8) = (128) - (120)

Lastly...

128 - 120 = 8

This means that if h(-8), then H = 8

Note that Based on the given scenario above, the purchase decision will be I will chose Ice cream bar fruit and frozen bar fruit.

If I am to purchase 550 frozen treats, I will buy:

Ice cream bar fruit  = 300

Frozen bar fruit = 250

Therefore,  for  Ice cream bar fruit , it will be = amount x cost price

Answer:

19.00 x h + 25.00 =

What you make in a day if you work for h hours.

Step-by-step explanation:

You automatically make $25.00 when you show up.

So the equation is asking for how many hours. If you get $19 per hour

then it would be $19.00 x h (how many hours you worked) + $25.00.

Example:

If you worked for 5 hours and one day, then the equation would be

19.00 x 5= 95

95 + 25 (for showing up that day) = 120

So if you worked 5 hours for one day you would make 120

(This was just an example to further explain how the equation worked)
