Answer:

r = 3

Step-by-step explanation:

Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,

Slope 'm' = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Slope of a line passing through (4, 2) and (r, -6) is 8.

8 = [tex]\frac{2+6}{4-r}[/tex]

8(4 - r) = 8

4 - r = 1

r = 4 - 1

r = 3

A baby giraffe measures 6 feet tall when it is
born, and it grows an average of foot each
month. Write an equation!

Answers

Answer:

equation 6+(½×n). n means the number of months

The equation that represents the situation is y = 6 + (1/2)x.

What is linear equation?

Equations whose variables have a power of one are called linear equations. One example with one variable is where ax+b = 0, where a and b are real values and x is the variable.

Given:

A baby giraffe measures 6 feet tall when it is born.

Initial height of baby=6 feet.

Average growth per months = 1/2

                                               =0.5 feet

Let x be the number of months.

And the height of a baby giraffe is y feet.

So equation is,

y = 6+0.5x

or, y = 6 + (1/2)x.

Therefore, the equation is  y = 6 + (1/2)x.

A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet

What is the height of the tank if it’s radius is 16 feet?

Answers

Volume of a cylinder = π radius² x height
Replacing with values given:
7252 = 3.14 ( 16 )² h
Solving for h (height)
7252 / 3.14(16)² =h
7252 /3.14 (256) =h
7252 / 803.84 = h
9.02 =h
The height of the tank is 9.02 feet
Answer : 9.02 feet

The height of the tank if it’s radius is 16 feet is,

⇒ Height = 9.02 feet

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A cylindrical fish tank at the zoo has a capacity of 7252 cubic feet.

Now, We know that;

Volume of a cylinder = π × radius² x height

Here, Radius is 16 feet.

Hence, We get;

Volume of a cylinder = π × radius² x height

7252 = 3.14 × 16² × h

⇒ 7252 = 803.84 h

⇒ h = 7252 / 803.84

⇒ h = 9.02 feet

Thus, The height of the tank if it’s radius is 16 feet is,

⇒ Height = 9.02 feet
