We have an rectangle triangle
Pythagoras therorem:
hypotenuse²=side₁²+side₂²
hypotenuse=61 feet
side₁=11 feet
side₂=height
(61 feet)²=(11 feet)²+ side₂²
3721 ft²=121 ft²+ side₂²
side₂²=3721 ft²-121 ft²
side₂²=3600 ft²
side₂=√(3600 ft²)
side₂=60 ft.
heigth=60 feet

Answer:
45 cm
Step-by-step explanation:
2 lines will divide the square in thirds. 2 additional lines will divide those thirds into ninths. Pat's 4 lines total 18 cm.
To divide the square into sixths requires 5 lines. To divide it into 36ths requires 5 additional lines. Hence the total number of lines on the second paper is 10/4 = 5/2 times the total on the first paper.
The total length of lines on the second paper is ...
(5/2)(18 cm) = 45 cm
The pendulum begins being planned at harmony position, this recommends you utilize a sine work since sin(0)=0
The time it takes to make one full upheaval is what's known as the period, spoken to by a T. You are given T= 4 sec. The separation from harmony is the plentifulness, An of the capacity which is given to be 6 in.
General wave work:
f(t) = A*sin( t*2pi/T - b) + c
A = |amplitude| ; remove from the midpoint
T = period; time it takes to make one full unrest
b = shifts the diagram right/left
c = shifts the diagram up/down
This diagram lies appropriately on the hub so there will be no compelling reason to move the chart
f(t) = 6*sin(t*pi/2)
y-pivot will be units of inches and x-hub, seconds
