I think 1392, don't take my word for it though.
(x-7)² = 36
The square root of both is √(x-7)² =√6²
x-7 = + or - 6
x-7 = 6 , then x = 13
x-7 = -6, then x = 1
So the values of x are 13 or 1
Answer:
A
Step-by-step explanation:
y - 3 = 4(x+5)
Let's convert the point-slope equation to y-intercept form: y = mx + b
Distribute the 4 to the equation inside the parenthesis
y - 3 = 4x + 20
Add 3 to both sides
y - 3 = 4x + 20
+ 3 + 3
y = 4x + 23
The slope of this equation is 4, meaning our equation's slope will have to be -1/4 to be perpendicular
y = -1/4x + b
Plug in the given x and y
-3 = -1/4(4) + b
-3 = -1 + b
Add 1 to both sides
-3 = -1 + b
+ 1 + 1
b = -2
y = -1/4x - 2
The volume of the cup would be 82.74. I used to formula Volume= pi* radius squared * height
