Answer:
B.
Step-by-step explanation:
The original equation is cos 64 = 32/k. To solve for k we need to isolate it. we can multiply by k then divide by cos 64. This gives us the equation k = 32/cos 64. Therefore, B is the right answer.
Answer:
y=-4x+11
Step-by-step explanation:
formula=
y=mx+B
find m
formula y2-y1/x2/x1
-5--1/4-3=-4/1=
-4 is your m
find b
-1=-4(3)+b
-1=-12+b
11=b
3.subsitiute into y=mx+b
The correct answer would be, "3y+3".

Answer: 48.84
Step-by-step explanation:
First, find the perimeter of the rectangle. 12+12+3+3=30ft. Next, find the perimeter of the semicircles. You can tell that if you put the semicircles together it would be a full circle. The formula for the perimeter of a circle is r2pi. The radius times 2 would be 6. Pi is approximately 3.14. 6 times 3.14 is 18.84. 18.84+30=48.84ft. Hope this helped :)
