1. A consumer magazine tested two kinds of engines. One was a standard

engine, and it was determined that its acceleration could be modeled by

f (t) = 6 + .7t feet per square second, t seconds after starting from rest. The acceleration of the turbo-charged model could be approximated by

g(t) = 6 + 6.1 t + .05 t^2 feet per square second, t seconds after starting

from rest. How much faster is the turbo-charged model moving than the standard model at the end of a 10 second trial?

Step-by-step explanation:

First, velocity function are found by means of integration, knowing that both engines start at rest and, lastly, velocities are evaluated at given time:

Standard Engine

Turbocharged Engine

Finally, the difference of the velocity of the turbocharged model with respect to the standard one is:

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

1 and 0
