Answer:
t = 9.08 sec
Explanation :
This requires the use of the kinematic equations.
u = initial velocity = 21.8 m/s
v = final velocity = 0
t = time = what we're trying to find.
So we use the equation that relates d, u, v and t. This is
d = distance = 99m
d = 
and since v = 0 this reduces to d = 
which rearranges to t = 
t = 
=9.08 seconds
t = 9.08 sec
Answer:
26.50 - 8 = 18.50 then divide by 5
Step-by-step explanation:
this equation will help u find the exact amount of one book
In this use SOHCAHTOA and according to this we will use CAH on your calculator do cos(72)times 4= 1.23 should be the answer
Answer:
2/3
Step-by-step explanation:
log27(9)
Factor the number: 27=3³
= log3³(9)
Apply log rule: loga^b(x) - 1/b loga(x).
log3³(9) =1/3 log3³(9)
=1/3 log3³(9)
Factor the number: 9=3²
=1/3 log3³(3²)
Apply log rule: loga(a^b) =b
log3 (3²) =2
1/3×2
=2/3
The answer is D=3 11(3*+1)=4(3*+8)
11(4)=4(11)
44=44
