She needs to score 90 points on her next test
79+61+54+90=284
284/4=71
S = sin (t) - 4 cos (2t)
.
ds/dt = cos (t) - 4 * 2 * (-sin (2t))
Or, v = cos (t) + 8 sin (2t) [v = velocity]
dv/dt = -sin (t) + 8 * 2 * cos (2t)
Or, a = - sin (t) + 16 cos (2t) [a = acceleration]
At t = pi,
a = - sin (pi) + 16 cos (2 * pi)
= -0 + 16 * 1
= 16
Answer: 16 ft / s^2.
Answer:
g = -2/3
Step-by-step explanation:
-g + 6 +2g = -4g - (-4)
g + 6 = -4g + 4
3g =-2
g = -2/3
Answer:
Step-by-step explanation:
Putting value of n = - 8 in the equation
F(n) = 2n− 5
F(-8) = 2(-8) - 5
= - 16 - 5 = - 21
Answer: The team needs to win 15 more games to get 90% winning percentage.
Step-by-step explanation:
80%=4/5 divide 15 by 5 and you get 3, which is 1/5 of 15, so you must multiply it by 4 to get 80% of 15 which is 3*4=12
If you want 90%(or 9/10) of 30, you do the same thing, and you get 27.
27-12=15.
