Answer:
Initial velocity is zero.
Step-by-step explanation:
According to second equation of motion

where s = distance traveled
t = time taken
a = acceleration
u = initial velocity
here in the question we have
s = 10 m
t = 1 second
a = 20
plugging the known value in order to find the unknown which is u (initial velocity)
[tex]10=u(1)+\frac{1}{2} (20)(1)^2[/tex
10 = u +10
gives u =0
therefore initial velocity is zero.
To find the approximately volume you will use the formula for finding the volume of a cylinder:
V = pi x r^2 x h
3.14 x 0.5^2 x 21
V = 16.485
The volume is approximately 16.49 cubic inches.
Answer: D is correct since the two angles are vertical angles and can be proven congruent by the vertical angle theorem
Step-by-step explanation:
For the first digit you are choosing from 2 digits
for the second digit you are choosing from 2 digits
for the third digit you are choosing from 2 digits
2*2*2=8
111
110
011
101
000
001
100
010
However......
A number doesn't usually start with a 0 or 0s.
Therefore, if you want 3-digit numbers and not just permutations using 0 and 1, then you must eliminate
011, 000, 001, and 010
Seeing that the first digit can't be 0, you choose from 1, then 2, and then 2 digits again; 1*2*2=4 numbers
You choose which answer best suits your problem.
