Answer:
36 feet
Step-by-step explanation:
3ft is 1 yard so you would multiply the 12 yards by 3 making 36.
I assume your question amounts to finding the period of f(t)=8sin(4 pi t). A period L is a positive number such that f(t+L)=f(t) for all t. Since sin(x) is 2 pi perodic we can find the least number L such that 4pi(t+L)=4*pi*t+2*pi. Multiplying out we get
4pi(t+L)=4*pi*t+4*pi*L and we want to find L such that we get 4*pi*t+2*pi, notice if we take L=1/2 we get the desiered result 4*pi*t+4*pi*1/2=4*pi*t+2*pi. This proves that L=1/2 and your function has a period of 1/2.
A is a base angle because... well... it's connected to the base.
B is a leg
C is the vertex angle
D is a leg
E is a base angle for the same reason as A.
F is the base
If the slope is -3/4, the equation would be y= -3/4x-5, if the slope is -34, the equation would be y= -34x -5
