You need to figure what increment each dash line represents. Since given -6 and -14 is 2 dash lines away, you find the difference
-14-(-6) = 8
Since it was 2 dashes away, 8/2 = 4
So, each increment is by 4.
Since this is the negative direction and the blue dot is 4 increments away,
-14-4-4-4-4= -30
The third angle would measure 39 degrees.
Answer:
D. The input force is equal to the output force
Step-by-step explanation:
A pulley changes the direction of the applied force, but does not change its magnitude. The mechanical advantage is the ratio of output force to input force, so must be 1 when the force magnitude does not change.
Ans: A
Sub t=2 in the equation
I saw the image that should have been posted with this word problem.
The rolls of wrapping paper is cylindrical in shape.
Roll A : length = 30 inches ; diameter = 3 inches
Roll B : length = 24 inches ; diameter = unknown
Lateral surface area = 2 π r h
Lateral Surface area of Roll A = Lateral Surface area of Roll B
2 * 3.14 * 1.5in * 30in = 2 * 3.14 * r * 24 in
282.60 in² = 150.72 in * r
282.60 in² / 150.72 in = r
1.875 in = r
diameter is 2 times the radius = 1.875 in * 2 = 3.75 inches
The diameter of Roll B is 3.75 inches.
