It’s an exponential growth because 1.15 indicates that the function is increasing by 15% and the number is greater than 1

What is the product of the 2 solutions of the equation x^2+3x-21=0

Advocard [28]

X²+3x-21=0

1) we solve this square equation:
x=[-3⁺₋√(9+84)] / 2=(-3⁺₋√93)/2
We have two solutions:
x₁=(-3-√93)/2
x₂=(-3+√93)/2

2) we compute the product of the 2 solutions found.
[(-3-√93)/2][(-3+√93)/2] =(-3-√93)(-3+√93) / 4=
=(9-93)/4=-84/4=-21

Answer: the product of the 2 solutions of this equation is -21

Which equation using x to represent time best represents the floor number of an elevator descending at a steady rate?

zepelin [54]

C. You'd be starting at a higher floor (positive number) and descending floors (negative number per x). If you assume x is time it's a little more logical and visual.

To start, we're given the range that x lies in: from -1 to 4. We know from the fact that $-1 \leq x$ that -1 will be included in that range, so we mark -1 on the number line with a solid circle. We also know from $x\ \textless \ 4$ that, while x can be any value up to 4, it does not include 4. We indicate this by drawing a hollow circle around 4 on the number line. Since x can be any value within this range, we make that fact clear by drawing a bold line between the points -1 and 4 on the number line. I've attached an image of what our final graph would look like.
