Answer:
Step-by-step explanation:
Given that,
Speed of a toy car, v = 7.2 m/s
Radius of the circular track, v = 1.5 m
We need to find the acceleration of the car. When an object moves in a circular path, it will have centripetal acceleration. It can be given as follows :
So, the centripetal acceleration of the toy car is 
. Hence, the correct option is (c).
Area = length x width
60 = (x+5) (x-2)
60 = x^2 + 3x -10
Subtract 60 from both sides:
x^2 +3x -70 = 0
Solve for x by finding 2 numbers when added together = 3 and when multiplied by each other = -70
x = -10 and 7
Since the sides have to be a positive number we need to use 7
The length = x+5 = 7+5 = 12 cm
The width = x-2 = 7-2 = 5 cm

Step-by-step explanation:
Answer:
Parent function is g(x) = x² a quadratic
Step-by-step explanation:
quadratic; translation down 4 units
-4 means the vertex will move down 4
A geometric sequence is a sequence with a common ratio multiplied by previous term to give the next. Lets call x the common ratio, so we know that 4 was multiplied by x to give the second term, and so forth until it was multiplied again and again by x until the 16384 was reached which happens to be the 13th term, that means that 4x was multiplied by x 12 more times to give 16384, that is:
4x^12 = 16384
x^12 = 4096
x = 4096^-12
x = 4.48 x 10^-44
that is the common ratio
