Given that f(x)=-3x^2+8x-5 and g(x)=4x-2 find the following values.

g(1)-f(10)

Give answer as an integer or decimal rounded to nearest tenth.

Analysis of an accident scene indicates a car was traveling at a velocity of 67.5 mph (30.2 m/s) along the positive x-axis at the instant the brakes were applied and then traveled a distance of

106 m

before hitting an obstacle at a velocity of

5.50 m/s.

Determine the car's acceleration a (assumed constant) and the time t between applying the brakes and hitting the obstacle. (Assume the car is moving in the positive direction. Indicate the direction with the sign of your answer.)

a= m/s2

t= s

A plane flies 450 kilometers with a bearing of 316° (clockwise from north) from Naples to Elgin. The plane then flies 740 kilometers from Elgin to Canton (see figure). Canton is due west of Naples. Find the bearing of the flight from Elgin to Canton. (Round to the nearest whole number.)

A bridge is to be built across a small lake from a gazebo to a dock. The bearing from the gazebo to the dock is S 41° W. From a tree x = 80 meters from the gazebo, the bearings to the gazebo and the dock are S 74° E and S 28° E, respectively (see figure). Find the distance from the gazebo to the dock. (Round your answer to the nearest whole number.)

A weight is oscillating on the end of a spring (see figure). The position of the weight relative to the point of equilibrium is given by

y = 1/4(cos(8t) − 7 sin(8t))

where y is the displacement (in meters) and t is the time (in seconds). Find the times at which the weight is at the point of equilibrium (y = 0) for 0 ≤ t ≤ 1. (Round your answers to two decimal places. Enter your answers as a comma-separated list.)
