Answer: 27a^3
It is 27a^3 because if you do 3×3=9 then 9×3= 27
Answer:
y=x-2
Step-by-step explanation:
the line is linear with a slope of 1/1
the y int is -2
plug into y=mx+b
y=x-2
Answer:

Step-by-step explanation:
The question is, how many x and y steps do I have to move the P picture to get it in the Q position. The answer is 2 to the left, so -2, and 4 down, so -4.
To Find :
Position vector at time
and
.
Solution :
r (t) = 2 (t −7)i + 12t j
Putting t = 5 s and t = 8 s, we get :
r(5) = 2( -2 )i + 60j
r(5) = -4i + 60j
r(8) = 2i + 96j
Now, to find speed differentiating the r(t) w.r.t t :

Hence, this is the required solution.
