Answer:
Hello! Mizuki here to help!
The correct answer for problem 9 is B.
The correct answer for problem 10 is also B.
Step-by-step explanation:
<em>Sorry if the work I did is confusing, if you don't get what I did, just comment below and I'll try my best to answer your question!</em>
problem 9 work:
3 x 4 + 5 x 8 + 4 x 8 + 3 x 8 =
12 + 40 + 32 + 24 =
108
problem 10 work:
17 x 24 + 8 x 15 + 15 x 24 + 8 x 24 =
408 + 120 + 360 + 192 =
1080
It is the addition property because you transfer -2 to the other side which makes +2
Your equation is:
(x - 6)² + (y + 8)² = 100
When you plug in (0, 0) into this equation, you get:
(0 - 6)² + (0 + 8)² = 100
(- 6)² + 8² = 100
36 + 64 = 100
100 = 100
Given a polynomial 
and a point 
, we have that
We know that our cubic function is zero at -4, 0 and 5, which means that our polynomial is a multiple of
Since this is already a cubic polynomial (it's the product of 3 polynomials with degree one), we can only adjust a multiplicative factor: our function must be
To fix the correct value for a, we impose 
:
And so we must impose
So, the function we're looking for is
You are solving for the height. Use the formula:
c² - b² = a² in which c = hypotenuse
(13)² - (5)² = a²
Simplify
169 - 25 = a²
144 = a²
Isolate the a. Root both sides
√144 = √a²
a = √144
a = √(12 x 12)
a = 12
C) 12 feet is your answer
