Hi there!
Let's solve this problem step by step!
To convert this formula to slope-intercept form, we must isolate y.
First bring 7x to the left by subtracting 7x from both sides of the equation.
Finally we need to divide both sides of the equation by 3.
Do some simple algebra and we find:

Do you remember how to find the area of a circle ?
Big Fat Hint: The area of a circle is (pi) x (its radius)² .
Can you find the area of the big circle ... the one with radius = 18 m ?
Do that. The whole big circle, just as if there was nothing inside it, and
no shaded region.
I'll wait.
Now, can you find the area of the small circle ... the one with radius = 12 m ?
Do that.
I'll wait.
The area of the shaded region is just
(the area of the big circle) minus (the area of the small circle) !
I got 180 pi or roughly 565.2 m². I could be wrong. You should check it.
Answer: 1. Acute 2. Complementary 3. Congruent 4. Obtuse 5.Right
6. Supplementary
Step-by-step explanation:
(I have attached an example for reference)
1) Product means multiply, so we will multiply the decimal numbers.
2) First multiply both the numbers just the way you multiply two whole numbers.
3) note that WHILE multiplying you DON'T put the decimal point. Put the decimal point once you get your FINAL answer.
4) Once multiplied, count the total number of places after the decimal in both the numbers which were given. i.e, in the example it's 2 decimal places, one decimal place in 24.5 and one in 3.2, which means the total decimal places here are two.
5) now in your answer, start counting the decimal places from the right side of the number. For example in 7840, we start counting two decimal places from the right side of it and stop at 4 and put a decimal point there. This way we get 78•40.
Hope that helps...
A. -7/2
(1/4)^x+1=31
x+1=(-1/2)logbase2(31)-1
x=(-1/2)logbase2(31)-1
x=-3.5 or -7/2
