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>
<em></em>
61+68+71+77+76+82+80=515 degrees
515/7=73
I can't figure out the answer to this one i'm really sorry but anytime!
thanks
Log shows exponent in wich you need to put base to get x,
so you have the only choice here it is A,
<span> 3^2 = x , here is the base 3, exponent 2,
</span>A. Log base of (3) x = 2
Answer 10 because 110 minus 100 is ten
