V=4/3? r^2 Suppose that, for the sphere in the video, instead of being told how fast the radius is changing, we're told that the

grigory [225]

Answer:

$\frac{dr}{dt}=0.01$ cm per second

$\frac{dS}{dt}=320 square centimeter per secondStep-by-step explanation:We are given that volume of sphere [tex]V=\frac{4}{3}\pi r^3$

Volume of sphere is increasing at a constant rate

$\frac{dV}{dt}=4$ cubic centimeters per second

We have to find the rate of radius at which increasing

when r= 10 cm

Differentiating w.r.t time

$\frac{dV}{dt}=\frac{4}{3}\pi\cdot3r^2\frac{dr}{dt}$

$4=4 r^2\frac{dr}{dt}$

$\frac{dr}{dt}= \frac{1}{r^2}=\frac}{1}{(10)^2}=0.01$ cm per second

Now ,we are given that surface area of sphere

$S=4\pir^2$

Differentiate w.r.t time then we get

$\frac{dS}[dt}=8\pir\frac{dr}{dt}$

$\frac{dS}{dt}=8\pi\times 20\times 2$

$\frac{dS}{dt}=320$ cm per second

Which compound inequality is equivalent to the absolute value inequality |b|>6?

Tom [10]

Answer:

Step-by-step explanation:

You have to solve the compound inequality $|b|>6.$

The absolute value $|b|$ means the distance from the number b to the origin. Thus, the inequlity $|b|>6$ has as solutions all numbers b that are at the distance from the origin greater than 6.

So, $b>6\text{ or }b$

What is the 1st term when -5z^2+7z^4+11z-8z^3 is arranges in descending order

Alexandra [31]

Answer: The first term is $7z^{4}$

Step-by-step explanation:

1. To rewrite the given polynomial in descending order, you must see the exponent of each variable of the terms. Then, you must arrange the terms from bigger to smaller.

2. Keeping this on mind, you have:

$7z^{4}-8z^{3}-5z^{2}+11z$

3. As you can see, the first term is: $7z^{4}$

12. A fruit basket contains oranges and grapefruits. One-third of the orange

frosja888 [35]

Answer:

There were 12 + 28 = 40 pieces of fruit in the basket.

Step-by-step explanation:

Suppose there were x oranges and y grapefruit.

Then we have

1 /3 x = 4

x = 4*3 = 12.

1/4 y = 7

y = 7*4 = 28.
