Answer:
Step-by-step explanation:
acceleration, a = 20 m/s^2
initial velocity, u = 0 since it starts from rest
final velocity, v = 400 m/s
v = u + at
400 = 0 + 20 t
400 = 20 t
t = 400 / 20
<u><em>t = 20 sec</em></u>
Hope this helps
plz mark as brainliest!!!!
4x plus 4y seems to be equal to that situation right there
(y^12)/5
9/45=1/5
x^5/x^5=1
y^16/y^4=y^12
Answer:
f(0) = 31
Step-by-step explanation:
We are given the following function:

f(0).
This is the value of f when
. So

So f(0) = 31
because 1+1+1+1=4 and thats 4 1's 1+1=2 2+2=4
