A motocross rider is in the air for 2.5 seconds. Your camera can take a picture every 0.125 second. Your friend's camera can tak
2 answers:
Answer: a) Our camera is 1.2 times faster than friend's camera.
b) We can take 20 pictures while the rider is in the air.
Step-by-step explanation:
According to the given problem
a) 1 picture in our camera takes time =0.125 seconds
1 picture in friend's camera takes time =0.15 seconds
The rate of pictures taken by our camera=
The rate of pictures taken by friend's camera=
Now, scale factor by which our camera is faster then friend's camera=
Thus Our camera is 1.2 times faster than friend's camera.
b) Number of pictures we can take while the rider is in the air [∵Duration of motocross rider is in the air = 2.5 seconds.]
Thus we can take 20 pictures while the rider is in the air.

Answer:
The multiplicative rate of change of the function is
Step-by-step explanation:
You are given the table
An exponential function can be written as
where b is the multiplicative rate of change of the function.
Find a and b. Substitute first two corresponding values of x and y into the function expression:
Divide the second equality by the first equality:
Substitute it into the first equality:
So, the function expression is
Check whether remaining two values of x and y suit this expression:
So, the multiplicative rate of change of the function is
Answer:
Step-by-step explanation:
For this case we are interested on the region shaded on the figure attached.
And we can find the volume with the method of rings.
The area on this case is given by:
And the volume is given by the following formula:
For our case our limits are x=0 and x=2 so we have this:
And if we solve the integral we got this:
And after evaluate we got this:
