Answer:
180’ - 130’
Step-by-step explanation:
You would have to multiply all the numbers. 4 X 3, 4 X 2, 3 X 2, the answer I got was 36.
The answer you are looking for is b = -6.
There are 2 ways to find this. You could use...
- Add together 7 and 12 to get 19, then subtract 19 from both sides to get b = -6. OR...
- Subtract 12 from both sides to get b + 7 = 1, then subtract 7 from both sides to get b = -6.
Either way, you will get the same answer of b = -6. One method is just longer than the other. I hope this helps!
Answer:
<em>V(t) = π(4cos πt -5sinπt) cm</em>
Step-by-step explanation:
Given the displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s = 4 sin πt + 5 cos πt, where t is measured in seconds, the average velocity of the body will be expressed as the change in displacement of thee particle with respect to time.
This is expressed mathematically as V = ds/dt
Differentiate the displacement function to get the velocity V
V = 4πcos πt + (-5πsin πt)
open the parenthesis
V = 4πcos πt - 5πsin πt
bring out the common factor
V = π(4cos πt -5sinπt)
<em>Hence the average velocity of the body during each time is expressed as </em>
<em>V(t) = π(4cos πt -5sinπt) cm</em>
