Zane climb up in 33 seconds
44•33 = 1452 m.
so, Zane start from 1313 + 1452 = 2765 m below the edge.
to reach the edge with constant speed, Zane need 2765/44 = 62.84 seconds
we can round it to 63 seconds
Answer:
D
Step-by-step explanation:
6(x + 8) = Plug in x with 4
6(4 + 8) =
6(12) =
72
Answer:
Step-by-step explanation:
a) the equation representing the parabola is expressed as
h = -16t² - 4t + 20
c) to determine the height after 25 seconds, we would substitute 25 for t into the given equation. It becomes
h = -16(25)² - 4(25) + 20
h = - 10000 - 100 + 20
h = - 10080
d) when the coin lands on the ground, the height would be 0. Therefore,
-16t² - 4t + 20 = 0
Dividing both sides of the equation by 4, it becomes
- 4t² - t + 5 = 0
- 4t² - 5t + 4t + 5 = 0
- t(4t + 5) + 1(4t + 5) = 0
- t + 1 = 0 or 4t + 5 = 0
t = 1 or t = - 5/4
Since t cannot be negative, then t = 1 second
The answer should be 11/84
Answer:
Yes
Step-by-step explanation:
you labelled it correctly. angle a is across from side a, and vice versa. nice job!! :)
