On a coordinate plane, a curve crosses the y- axis at (0,1). It has a minimum of negative 1 and a maximum of 1. It goes through 2 cycle at 2 pi.
I think its c. The communicative property of multiplication state that you can multiply in any order <span />

Answers are in bold in explanation
Step-by-step explanation:
We are given the equation:
y = -7x + 8
The first x value is 0
y = -7(0) + 8
y = 8
(0, 8)
The next x value is 7
y = -7(7) + 8
y = -41
(7, -41)
Now we are given the Y value instead of X, so we do this:
36 = -7x + 8
Subtract 8 on both sides to leave -7x alone
28 = -7x
Divide by -7 on both sides to isolate x
-4 = x
(-4, 36)
The correct answer is C) (5×10⁴)(1×10²)
Explanation:
The number of trees can be calculated by the formula:
trees = density × area
Consider that the problem says that the researcher makes an approximation, and the answers have numbers written in scientific notation.
The density is 86 trees/km²,
which can be rounded to 100 trees/km²
and written as <span>1×10².
Therefore, density = </span>1×10² trees/km²
The area of a square can be calculated by the formula:
A = s²
= 220²
= 48400 km²
which can be roundend to 50000
and written as <span>5×10⁴
Therefore, area = </span>5×10⁴ km²
Now, we can substitute in the original formula:
trees = (1×10²)(5×10⁴)
