L = 2W
A = 50
A = L x W
50 = 2W x W
50 = 2W^2
W^2 = 25
W = 5
so L = 2W = 2(5) = 10
P = 2(L+W)
P = 2(10+5)
P = 2(15)
P = 30
answer
P = 30 in
Answer:
eight away .7 can be used into 3 4 times with a sum of 2.8 and that leaves .2 which would be left out since it is not a whole .7 so C
Step-by-step explanation:
Given that the function is:
y=a cos( bx+c), or y=a sin(x+c)
then the period is calculated as T= 2π/b and if T=2:
2=2π/b
b=2π/2=π
Therefore, the correct answer is option B, y=3 cos πx.
