Answer:

t= 2.22 seconds.

Step-by-step explanation:

1) You need to find the vertical velocity.

38*sin(35) = 21.7959

2) You need to use the t=v1y/a formula to find the time to get to the top.

v1y= the vertical velocity, 21.7959

a= Acceleration, 9.8

t=21.7959/9.8

t=2.22

0.9478 mpg.

And the second statement is

B. I this we have to tell the intercept of the plane in the given Relationship.

So, It is inappropriate to interpret the intercept because no cars get 0 mpg in the city.

So, In this relationship between the number of miles per gallon on the highway and that in the city for some cars are:

For each additional city mpg, the highway value goes up by
