Answer:
A) 
,
B) The aceleration is constant due to 
C) t=8,81s
Step-by-step explanation:
Be y as the heigh (y) of the roof of the empire state (381m)
A) 
to 
then v=-a.t, so (
) ; acceleration of gravity
since the acceleration is down the falling speed is negative
B) The aceleration is constant due to
C) 
Answer:
b
Step-by-step explanation:
b is the answer
Answer:
<u>x = 3</u>
Step-by-step explanation:
Equating the secants :
- 10 (10 + 5x + 2) = 9 (9 + 7x)
- 50x + 120 = 81 + 63x
- 63x - 50x = 120 - 81
- 13x = 39
- x = 3
The value of k that would satisfy the expression is "1". How to get this, the solution is shown below:
xky4 (2x3 + 7x2y4) = 2x4y4 + 7x3y8
Distribute xy4 to the parentheses such as:
k (2x4y4 + 7x3y8) = 2x4y4 + 7x3y8
Divide both sides by 2x4y4 + 7x3y8 such as shown below:
k = (2x4y4 + 7x3y8) / (2x4y4 + 7x3y8)
k=1
The answer is "1".
