Answer:
C. Amplitude = 3 feet; period = 8 hours; midline: y = 4
Step-by-step explanation:
The midline is halfway between the lowest point and the highest point.
y = (1 + 7) / 2
y = 4
The period is the time it takes for a full cycle. So the period is 8 hours.
The amplitude is the distance from the midline to the lowest or highest point.
a = 4 − 1 = 3, or a = 7 − 4 = 3
It's also half the distance between the lowest and highest points.
a = (7 − 1) / 2
a = 3
X= -y + 1/2z+ -19/2
Hope it helps
Since angle 4x and 8x look like supplementary angles 4x+8x=180°. After solving that equation x=15. Plug that number in and 4x=60° and 8x=120°
Answer:
48
Step-by-step explanation:
You will be using the Pythagorean theorem for this problem. assuming the bigger triangle is double the size of the smaller triangle on the right, we would first plug in the numbers for the smaller triangle: 
which would come out to 21.7. then we could say that since like i said before the bigger triangle is double the other one, the bottom side of the triangle would be 32 (16 + 16) and would use the pythagorean theorem again, giving us our answer.
