Answer:
v = 3.64 ft/s
Step-by-step explanation:
Given that,
Radius of a carousel, r = 18 feet
It takes 31 seconds to complete revolution.
We need to find the linear speed of the carousel at its outside edge. Distance covered is equal to the circumference of the circle.
d = 2πr
d = 2π × 18 = 113.09 feet
Let v is the linear speed. It can be given by :
So, the linear speed of the carousel is 3.64 ft/s.
Answer:
cos(18°)=sin(72°)
Step-by-step explanation:
we know that
In a right triangle
cos(A)=sin(B)
If A and B are complementary angles
so
A+B=90°
In this problem
A=18°
B=90-18=72°
therefore
cos(18°)=sin(72°)
22*22+22*22 I think is the answer which would give you 968 yds. Hope this helps:)
Hi!
The graph "x = 78" represents a vertical line passing through the point (78, 0).
Parallel lines always have the same slope, and for this equation a vertical line has an "undefined" slope.
Perpendicular lines have opposite inverse slopes. A line that's perpendicular to a vertical line is, of course, a horizontal line. Horizontal lines have a slope of 0.
Parallel to the equation: undefined
Perpendicular to the equation: 0
Hope this helps! Let me know if you need any other help! :0)
