PEMDAS. parenthesis, exponents, multiple or divide (whichever come first from left to right), add or subtract (whichever comes first from left to right)
So first do stuff in parenthesis.
Then do divide because thats next on the list and it happens earlier than the multiply one.
So, A
H=-5(t^2 - 16t)
H=-5(t^2 - 16t +64)+320
H=-5(t-8)^2 +320
Vertex is at (8, 320)
The max height is 320 m.
For number 10 the y-intercept is going to be at -1 1/3 not -1.
Answer:
144 degrees
Step-by-step explanation:
9x + 27 = 6x + 66
3x + 27 = 66
3x = 39
x = 13
9(13) + 27 = 144
