The first choice: <span>(x + 1)(x + 8)</span>.
1+8=9
1*8=8
Answer:
Step-by-step explanation:
R-value can range from -1 to 1 with correlation being strongest at -1 and 1 and weakest at 0.
So the answer is D. -0.9.
Answer:
Functions a(x) and b(x) intersect each other at x = 2.
We know that the trigonometric identity that uses the adjacent side and the hypotenuse is cosine. We can set this up as:

We need to solve for x, so let's isolate it:

So,
x = 10.2 units
