Answer:

236.22 cubic centimeters

Step-by-step explanation:

We need to find volume of 3 tennis balls and subtract it from volume of the cylinder to get our answer.

Volume of sphere (tennis ball) = $\frac{4}{3}\pi r^3$

Note: Radius is half of diameter, which is r = 6.7/2 = 3.35

Volume of 3 tennis balls = $3*\frac{4}{3}\pi r^3\\=3*\frac{4}{3}\pi (3.35)^3\\=472.44$

Volume of Cylinder = $\pi r^2 h$

Note: radius is 3.35 and height is diameter of 3 tennis balls stacked on top of each other, so height is 6.7 * 3 = 20.1

Hence,

Volume of Cylinder = $\pi r^2 h\\=\pi (3.35)^2 (20.1)\\=708.66$

amount of space not taken up = 708.66 - 472.44 = 236.22 cubic centimeters

A truck starts off 180 miles directly east from the city of Hartville. It travels due south at a speed of 45 miles per hour. Aft

Degger [83]

Answer:

11.82 mph

Step-by-step explanation:

The angle between the direction of travel and the direction to the city of Hartville is ...

arctan(180/49) ≈ 74.77°

The speed from the direction of Hartville is the the actual speed multiplied by the cosine of this angle:

speed from Hartville = (45 mph)×cos(74.77°) ≈ 11.82 mph

Comment on the solution

There are other approaches you can use to solve this. One is to compute the change in distance over a small period of time, such as 0.02 hours.

0.01 hours before the time of interest, the distance to the city is ...

d1 = √(180² +(49-.01(45))²) ≈ 186.4326 . . . miles

0.01 hours after the time of interest, the distance to the city is ...

d2 = √(180² +(49+.01(45))²) ≈ 186.6690 . . . miles

Then the rate of change of distance is ...

(d2 -d1)/(t2 -t1) = (186.6690 -186.4326)/0.02 = 11.82 . . . mi/h

Another is to write the distance equation and differentiate it. (You will find the solution looks very much like the trig solution above.)

d = √(180² +(45t)²)

dd/dt = 45²t/√(180² +(45t)²) . . . . . to be evaluated at t=49/45

rate of change = 45(49/√(180²+49²)) ≈ 11.82 . . . mi/h

Please help I need to know the answer for x

GuDViN [60]

Answer:

x > 6

Step-by-step explanation:

add 2 on both sides so it becomes x/-3 < -2 then multiply both sides by -3 then x is greater than 6
