Answer:
a=6 s 2+24 s+24
Step-by-step explanation:
If you are trying to solve for a then your answer is
a=6 s 2+24 s+24
If you are trying to solve for s then your answer is
s =
-√
6
a
/ 6 =−
2
so did you get what I solved the answer is D ok
Answer: Because the a-value is negative.
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: y = a(x - h)² + k where
- "a" is the vertical stretch
- -a is a reflection over the x-axis
- h is the horizontal shift (positive = right, negative = left)
- k is the vertical shift (positive = up, negative = down)
Given: g(x) = - (x + 1)² - 3
↓
a= -1
Since the a-value is negative, the parabola will be reflected over the x-axis which will change the curve from (U-shaped) to (∩-shaped).
Answer: 0.8
Step-by-step explanation:
Let's assume that 5 puzzles were solved in 5mins. That is, 1min for each puzzle to be solved.
From our assumption, our sample size will be 5.
The probability that a subject will solve more than 1 puzzle will be number of occurrence from 2 to 5 which is 4.
This gives: 4/5 = 0.8 to one decimal place.
