Answer:
90.6m
Step-by-step explanation:
Initial speed = 8m/s
Time = 4.3 s
In studying the motion of an object, we often make use of kinematic equation
s = ut + 1/2at^2
v^2 = u^2 + 2as
a = (v - u) / t
v = final velocity
u = initial velocity
s = distance or height
t = time
a = acceleration due to gravity
Given time to hit the ground as 4.3s, we calculate the height by using
s = ut + 1/2at^2
Since the stone is moving against gravity, a is negative
u = 0
s = 0(4.3) +1/2(-9.8)(4.3)^2
s = -90.6m
The height of the cliff is 90.6m
To find this answer, just look at the place value next to the one you are trying to find.
You are trying to find the whole number (or 7). The place value digit to the right is 4, which is less than 5. Round down
Your answer is 7

He is correct because if you break 13 up into 10 and 3 and you multiply them individually you get 50 and 15 you then add the and you get 65
Answer:
5
Step-by-step explanation:
13^2=169
12^2=144
169-144=25
Root 25 is 5
There are 6 outcomes for the cube and 4 for the spinner. So you can multiply 6 and 4. That gives you 24. The answer is C. 24. Hope this helps!
