3. A sphere has a volume of 3000 m.3 Find its diameter.
nekit [7.7K]

Answer:

8.565

Step-by-step explanation:

Volume=4/3pir^3

3000m^3=4/3pir^3

3000/4/3=pir^3

25/pi=r^3

approx 78.539=r^3

r=4.2825

we know,

2r=d

d=2×4.2825

d=8.565

You can round the answer off yourself :3

Prove that (n+5)^2 - (n+3)^2 is a multiple of 4 for all positive integer values of n.
Drupady [299]

Answer:

(n+5)² - (n+3)² =

= (n² + 10n + 25) - (n² + 6n + 9)

= n² + 10n + 25 - n² - 6n - 9

= 4n + 16

= 4(n + 4) ⋮ 4

IS ANYONE HERE GOOD AT CALCULUS?? IF SO, PLEASEEEE HELP ME!!!! An object’s velocity at time t is given by v(t) = –2 sin t. Let s
Bingel [31]

Answer: C

Step-by-step explanation:

Since we are given velocity, which is the first derivative, we have to fidn the antiderivative of velocity to get position.

∫-2sint dt

s(t)=2cos(t)+C

Since we are given s(0)=0, we can plug in the values to find C, constant.

0=2cos(0)+C

0=2(1)+C

0=2+C

C=-2

Now that we know our constant, we can find out position.

s(t)=2cos(t)-2
