Answer:
64
Step-by-step explanation:
x-13+2x+1=180
3x-13+1=180
3x-12=180
3x=180+12
3x=192
x=192/3
x=64
4x+7=x-2
-x -x
3x+7=-2
-7 -7
3x=-9
3 3 You divide -9 by 3.
x=-3
Your welcome

Answer:
The arc length, radius and the included angle are related as
r\theta=\widehat {XYZ} where \theta is in radians.
The radius r is given by
r=\frac{\widehat {XYZ} }{\theta} \\ r=\frac{10.8}{1.8} \\ r=6\;units
Correct choice is (B).
Step-by-step explanation:
The colony will die out when P(t) = 0.
-8t + 66 = 0
8t = 66
t = 66/8 = 8.25
The colony will die out after 8.25 seconds.
P(t) = t^2 + 1 = 9
t^2 = 9 - 1 = 8
t = sqrt(8) = 2.83 minutes.
