When you multiply a negative and a positive you will get a negative answer so 3*7 is 21 so -3 * 7 is -21
Answer:
-2 m/s^2
Step-by-step explanation:
Just as you would calculate the velocity when a body moves from point A to point B in a time T, we are going to calculate the acceleration as the difference of the velocities (final - initial) and divide it by the time it took:
Velocity_final = 10 m/s
Velocity_initial = 20 m/s
Time = 5 s
acceleration = (Velocity_final - Velocity_inital)/Time
= (10 m/s - 20 m/s)/5 s
= (-10 m/s) / 5s
= -2 m/s^2
The acceleration in m/s^2 is -2

Answer:
= 8.33 inches
Step-by-step Explanation
First add 49 + 16, which equals 65, and subtract that result from 180, since a triangle equals 180 degrees and you find out angle C is equal to 115 degrees.
Now using the formula sinA/a = sinB/b = sinC/c, plug in values and you'd get the equation sin49 x 10/sin115. After solving the equation you'd get about 8.32729886047258 inches.
= 8.33
