Answer:

Step-by-step explanation:
we are given equation for position function as

Since, we have to find acceleration
For finding acceleration , we will find second derivative




now, we can find derivative again




Firstly, we will set velocity =0
and then we can solve for t

we get

now, we can plug that into acceleration
and we get


Answer:
d) 1/2 ÷ 4 = 1/2 • 4/1

Answer:
300
Step-by-step explanation:
there are 9 15's in 120 which means its going by 15's 3 x 5= 15 and if it says 6 that means its timesed by 2. 15 x 2= 30 then 30 x 10= 300
Answer: 
Step-by-step explanation:
- Dilation is a transformation, in which the size of the image gets changed but not shape.
The rule of dilation with scale factor k and wither origin as center of dilation :
(x,y) → (kx, ky)
Here ,
, center of dilation = Origin
Then, the rule best represents a dilation to create pentagon PQRST will be :
