Answer:
63.5
Step-by-step explanation:
If one didn't take a 10 minute break he could drive 60 mph totalling 180 minutes but since he did and 180 - 10 = 170. He/she has to drive 180 miles in 170 min. so we take so we divde 180/170 and multiply by 60. If you round it to the nearest tenth you get 63.5
In step 3, Mark forgot to multiply 5 · 5, so he ended up with 5 in the denominator instead of 5 · 5 = 25
Answer:
Right here again! Let me help.
Step-by-step explanation:
Its C ! The distance is 6 in between and the rate is 10. 10 x 6 = 60 !
Answer:
This is a compression by a factor of 3 in the x direction
(horizontal compression by factor of 3)
This reflects it about the x axis
Step-by-step explanation:
f(x)=|x|
h(x) = |3x|
This is a compression by a factor of 3 in the x direction
g(x) =-|3x|
This reflects it about the x axis
Answer:
Depth = 7.06 m
Velocity = 11.77 ms-1
Step-by-step explanation:
We use the equation of motion:-
s = ut + 1/2 g
where s = distance fallen , t = time , u = initial velocity and g = 9.81 ms^-2 , the acceleration due to gravity.
So s = 0(t) + 1/2 * 9.81 (1.2)^2
= 7.06 m to nearest tenth.
We use another equation of motion to find the final velocity:-
v^2 = u^2 + 2gs where v = final velocity
v^2 = 0 + 2*9.81 * 7.06
= 138.52
v = √138.52 = 11.77 m s-1
