5:35-5:52 I need how much minutes from 5:35 from 5:52 please answer

2 answers:

8 0

Since these both are on the same hour we'll ignore the 5. We end up having :35 and :52. We'll subtract 35 from 52 which gives us 17. The answer to this is 17 minutes.

Hello , how to do 6(iii)?

Doss [256]

Answer:

$\displaystyle \frac{dS}{dt}=\frac{3}{50r}$

Step-by-step explanation:

Water is being pumped into an inflated rubber sphere at a constant rate of 0.03 cubic meters per second.

So, dV/dt = 0.03.

We want to show that dS/dt is directly proportional to 1/r.

In other words, we want to establish the relationship that dS/dt = k(1/r), where k is some constant.

First, the volume of a sphere V is given by:

$\displaystyle V=\frac{4}{3}\pi r^3$

Therefore:

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

Next, the surface area of a sphere S is given by:

$\displaystyle S=4\pi r^2$

Therefore:

$\displaystyle \frac{dS}{dt}=8\pi r\frac{dr}{dt}$

We can divide both sides by 2:

$\displaystyle \frac{1}{2}\frac{dS}{dt}=4\pi r\frac{dr}{dt}$

We can substitute this into dV/dt. Rewriting:

$\displaystyle \frac{dV}{dt}=r\Big(4\pi r\frac{dr}{dt}\Big)$

So:

$\displaystyle \frac{dV}{dt}=\frac{1}{2}r\frac{dS}{dt}$

Since dV/dt = 0.03 or 3/100:

$\displaystyle \frac{3}{100}=\frac{1}{2}r\frac{dS}{dt}$

Therefore:

$\displaystyle \frac{dS}{dt}=\frac{3}{50r}=\frac{3}{50}\Big(\frac{1}{r}\Big)$

Where k = 3/50.

And we have shown that dS/dt is directly proportional to 1/r.

A share of stocks gained 12 points, then lost 114 points, and then gained 218 points. Find the overall change in its value.

VLD [36.1K]

Answer:

The overall change is 116points gained

Step-by-step explanation:

Points gained = 12points

Points lost = 114points

Points gained = 218points

Unknown:

Overall change in its value = ?

Solution:

The overall change = Total points gained - Total points lost

= (218 + 12) - 114

= 116points

The overall change is 116points gained

What is 1102 using the polynomial identity (a+b)2=a2+2ab+b2 ?

Virty [35]

Answer:

"Let the smaller value a = 10 and the larger value b = 100. Than a^2 + 2ab + b^2 is 10^2 + 2 * 10 * 100 + 100^2. This can be simplified to 12100. So, 110^2 is equal to 12100."

Hope this helped!
