Answer:
prepare for unexpected bills or emergency repairs
Step-by-step explanation:
I'm going to assume that you meant the equation to be:
So we're going to take that equation and we're going to solve for h(-2).
This means that we plug in a '-2' for every x in the equation:
So when we solve the equation for h(-2), we get 0 as our answer.
Answer:
radius: 4√(2π)/π "four times the square-root of two pi, over pi"
Step-by-step explanation:
The formula for area of a circle is
A = πr², where A is the area, π is the constant value pi, and r is the radius
We are given an area of 32 m² and need to find the radius, so we have...
32 = πr²
First, divide by π to get the r term by itself
32/π = r²
Now take the square root of both sides...
√(32/π) = r
Simplify the left side, you can distribute the square root to the numerator and the denominator...
(√32)/(√π) = r
√32 breaks down into 4√2 using a factor tree. You can't have a square root in the denominator so multiply top and bottom by √π
[(4√2)(√π)]/[(√π)(√π)] = r
This simplifies to
4√(2π)/π
Answer:
8) complementary, 45°
9) supplementary, 5x = 135°, (x+18) = 45°
10) alternate angles, 49°
Step-by-step explanation:
For 8th question
35 + 5x = 90° because the given angles are complementary
5x = 90 - 35
5x = 45
x = 9
For 9th question
5x + x + 18 = 180° because the given angles are supplementary
6x = 180 - 18
6x = 162
x = 27
For 10th question
3x + 1 = 49° because these angles are alternate
3x = 49 - 1
3x = 48
x = 16
