Answer:
9.5 minute
Step-by-step explanation:
500 - 25 = 50x
x = 
x = 9.5 minute
It is already in identity.
cos (x - y) - cos (x + y) = 2 sin(x) sin (y)
1/4 off means 0.25 * 28

Sale price = 28-7
= 21
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).
