I think the answer is the 3rd rectangle but I'm not too sure I'm sorry
Answer:
-(23/6)π
-(19/6)π
-3π
Step-by-step explanation:
cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t
sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0
Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,
sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π
Answer:
24 miles per gallon
Step-by-step explanation:
Step one:
given data
total distance covered= 480miles
The total amount of gallons used is = 20
The miles per gallon
= 480/20
=24 miles per gallon
Step two:
hence the equation that we used in solving the problem is stated as
miles per gallon= total distance/total gallon sused

Answer:
Step-by-step explanation:
Amount paid by Joanne before promotion = 74 + 59 + 69 = $ 202
a) Amount saved if she switches to "3 for 129 plan" = 202 - 129 = $ 73
Percentage of saving = 
= 36.13 = 36%
b) Amount saved after the first year = 202 - 139 = $ 63
Percentage of saving = 
= 31.18 = 31%
