If you consult the unit circle, you will see that:
3pi/4 in degrees is 3pi/4 * 180/pi = 3/4 * 180 = 135 degrees. And please refer to the attachment to how you can obtain the values above.
Now, lets multiply it together.
So, <span>cos(3pi/4)sin(3pi/4) =
-1/2</span>
Answer:
the answer is C.-1/128......
Answer:
x =88/9
Step-by-step explanation:
the rule of B.E.A.N. states that the distributive property among the other mathematical properties must converge all numbers from their original state into a hyroglyphic form of theorem outside our magnitude and ultimately equal x=88/9
Given that height, h(t) of a tennis ball is modeled by the equation h(t)=<span>-16t^2 + 45t + 7, the time taken for the ball to reach maximum height will found as follows:
at maximum height:
h'(t)=0
but from the equation:
h'(t)=-32t+45=0
solving for t we get
t=45/32
t=1.40625~1.4 seconds
Thus the time taken to reach maximum height is 1.4 seconds
