Answer:
y = 10/3x + 20
Step-by-step explanation:
First, we need to find the slope of the function. We can do that by using two points and inserting them into the slope formula. It can be any two but I'll just pick (3, 30) and (6, 40).
m = y₁ - y₂ / x₁ - x₂
m = 30 - 40 / 3 - 6
m = -10/-3
m = 10/3
Now we know the slope is 10/3.
In slope-intercept form, the y-intercept is the constant at the end of the equation. The table of values tells us that the y-intercept is located at (0, 20). So the equation of the linear function is y = 10/3x + 20.
Answer:
= 2
Step-by-step explanation:
Step 1- Substitute the variables
(2(4)-2)÷3
Step 2- Multiply
(2(4)-2)÷3
Step 3- Subtract
(8-2)÷3
Step 4- Divide
6÷3=2
Answer:
6.28 gallons
Step-by-step explanation:
first we need to find the area of a half sphere, and then find how much paint will be needed for that area.
The area of a sphere:

thus, the area of half a sphere is:

we know that the radius is:

we substitute this to find the area of the half sphere (the area they need to paint):

now the question is how many gallons of paint are needed to paint 2,513.27 square feet.
We are told that 1 gallon covers 400 square feet
thus, we must divide 2,513.27 by 400:

6.28 gallons of paint are needed.
