When an object moves on a circular path, the centripetal force varies directly as the square of the velocity and inversely as th

e radius of the curve. If the force is 640 lb for a velocity of 20 mi/h and radius of 5 m, find the radius for a velocity of 30 mi/h and a force of 1800 lb.

Answer: I think it's 40

Step-by-step explanation:

I don't know, I just need points. If you take the 640 and divide it by the nearest angular velocity, then square it, then divide by the radius, you get Bolivia

Answer:

  16% increase

Step-by-step explanation:

A percentage change can be calculated from ...

  percentage change = ((new value)/(old value) -1) × 100%

  = (58/50 -1) × 100% = (1.16 -1) × 100%

  = 16%

A student needs to make a square cardboard piece. The cardboard should have a perimeter equal to at least 92 inches. The functio
saveliy_v [14]

Answer: d. s ≥ 23


Step-by-step explanation:

Let s be the side of the square.

We know that the perimeter of a square =4s

Let f(s)=4s

If the cardboard should have a perimeter equal to at least 92 inches, the inequality would look like

4s\geq 92

Divide both sides by 4, we get

s\geq\frac{92}{4}\\\Rightarrow\ s\geq23

Thus, d. is the right answer. The reasonable domain of f(s) is s\geq23

Which is greater: An angle showing a turn through 1/6 of a circle or an angle showing to turn through 1/5 of a circle explain yo
Rashid [163]

Answer:

An angle showing a turn through 1/5 of a circle is greater

Step-by-step explanation:

we know that

A complete circle represent 360\°

so

An angle showing a turn through 1/6 of a circle is

(360\°)*(\frac{1}{6})=60\°

An angle showing a turn through 1/5 of a circle is

(360\°)*(\frac{1}{5})=72\°

therefore

An angle showing a turn through 1/5 of a circle is greater
