A pool in the shape of a cylinder with a height of 6 m and a base radius of 7 m is drained for repair. If the rate at which the pool is being drained is 3 m3/min, find the rate at which the water level is falling when the water is 4 m deep to the nearest hundredth.
Answer:
The rate at which the water level is falling when the water is 4 meters deep to the nearest hundredth is 0.02 meters per minute.
Step-by-step explanation:
The volume of a cylinder ([tex]V[/tex]), measured in cubic meters, is represented by the following formula:
[tex]V = \pi\cdot r^{2}\cdot h[/tex] (1)
Where:
[tex]r[/tex] - Radius, measured in meters.
[tex]h[/tex] - Height, measured in meters.
Then, we differentiate (1) in time:
[tex]\dot V = 2\pi \cdot r\cdot h \cdot \dot r +\pi \cdot r^{2}\cdot \dot h[/tex] (2)
Where:
[tex]\dot V[/tex] - Rate of change of the volume, measured in cubic meters per minute.
[tex]\dot r[/tex] - Rate of change of the radius, measured in meters per minute.
[tex]\dot h[/tex] - Rate of change of the height, measured in meters per minute.
Then, we clear the rate of change of the height:
[tex]\pi \cdot r^{2}\cdot \dot h = \dot V-2\pi \cdot r\cdot h \cdot \dot r[/tex]
[tex]\dot h = \frac{\dot V - 2\pi \cdot r\cdot h\cdot \dot r}{\pi \cdot r^{2}}[/tex]
[tex]\dot h = \frac{\dot V}{\pi \cdot r^{2}}-\frac{2\cdot h\cdot \dot r}{r}[/tex]
[tex]\dot h = \frac{1}{r}\cdot \left(\frac{\dot V}{\pi \cdot r}-2\cdot h\cdot \dot r \right)[/tex] (3)
If we know that [tex]\dot V = -3\,\frac{m^{3}}{min}[/tex], [tex]r = 7\,m[/tex], [tex]h = 4\,m[/tex] and [tex]\dot r = 0\,\frac{m}{min}[/tex], then the rate of change of the height is:
[tex]\dot h = \left(\frac{1}{7\,m} \right)\cdot \left[\frac{-3\,\frac{m^{3}}{min} }{\pi\cdot (7\,m)-2\cdot (4\,m)\cdot \left(0\,\frac{m}{min} \right)} \right][/tex]
[tex]h = -0.019\,\frac{m}{min}[/tex]
The rate at which the water level is falling when the water is 4 meters deep to the nearest hundredth is 0.02 meters per minute.

Step-by-step explanation:
At what rate should $1,000 be invested compounded
continuously to produce a final balance of $2,000 in
5 years?
A. 0.139%
B. 0.231%
C. 13.863%
D. 23.105%
Answer:
14.9%
Step-by-step explanation:
Using the compound interest formula;
A = P(1+r)^t
A is the amount = $2000
P is the principal = $1000
r is the rate
T is the time = 5 years
Substitute the given values into the formula;
2000 = 1000(1+r)^5
2000/1000 = (1+r)^5
2 = (1+r)^5
[tex]\sqrt[5]{2} \\[/tex] = 1 + r
r = 1.149 - 1
r = 0.149%
Hence the required rate is 14.9%

Find the value of f(5) for the function.
f(x)=−6(x+1)
Answer:
f(5) = -36
Step-by-step explanation:
Plug in 5 as x:
f(x) = −6(x + 1)
f(5) = -6(5 + 1)
Simplify:
f(5) = -6(6)
f(5) = -36
So, f(5) = -36
What is the first step needed to solve 4 over 7 multiplied by x minus 5 equals negative 13 ? (1 point) a Subtract 13 from both sides b Divide both sides by 7 c Add 5 to both sides d Multiply both sides by 4
Answer:
c Add 5 to both sides
Step-by-step explanation:
The statement is represented by the mathematical expression;
4 over 7 multiplied by x minus 5 equals negative 13
4/7 * x - 5 = 13
a Subtract 13 from both sides
This option is wrong because there is no point making the eight side of the equation zero
b Divide both sides by 7
This option is wrong because it is only making the equation complex and not simple.
c Add 5 to both sides
Among all the options, this is correct. The reason is because it would simplify the expression in the left side of the equation.
d Multiply both sides by 4
This option is wrong because it is only making the equation complex and not simple.

the price of a stock in a computer company is 25% greater than the cost of stock in a bank, b. write an expression for the sum of the prices of the stocks in the computer company in the bank in terms of b
Answer:
1.25b
Step-by-step explanation:
Let the cost of stock in a bank, b.
Now, since the price of a stock in a computer company is 25% greater than the cost of stock in a bank, it means;
the cost of stock in the computer company = b + 25%b = 1.25b
Thus,total cost of stock in both bank and computer company is;
Sum = 1.25b

Answer:
[tex]0.45, 0.54[/tex]
Step-by-step explanation:
Given
[tex]0.54\ and\ 45\%[/tex]
Required
Order from least to greatest
We start by converting 45% to decimal
[tex]45\% = \frac{45}{100}[/tex]
[tex]45\% = 0.45[/tex]
So, the numbers are:
[tex]0.54\ and\ 0.45[/tex]
On a number line:
0.45 comes before 0.54
This implies that:
[tex]0.45 < 0.54[/tex]
And the required order is:
[tex]0.45, 0.54[/tex]

The side length of an equilateral triangle whose side length 4.3 centimeter.
Given that,
The side length of an equilateral triangle is 5 centimeters.
We have to determine,
The length of an altitude.
According to the question,
An altitude of a triangle is the perpendicular segment from a vertex of a triangle to the opposite side (or the line containing the opposite side).
The side length of an equilateral triangle is 5 centimeters.
Altitude of Equilateral Triangle is,
[tex]h = \dfrac{\sqrt{3}}{2}a\\\\h = \dfrac{\sqrt{3}}{2}5\\\\h = \dfrac{5\sqrt{3}}{2}\\\\h = 4.33[/tex]

Can someone help me I have two more other questions they are 15 points each I just posted them right now! Thanks so much
Answer:
$10 coins: 21
$20 coins: 24
Step-by-step explanation:
heyy me again
So we can create 2 equations where
x = number of $10 coins
y = number of $20 coins:
x + y = 45
10x + 20y = 690
we can move equation 1 around so that we can get a value of x
x = 45 - y
now we can substitute x into the second equation
10(45 - y) + 20y = 690
450 - 10y + 20y = 690
10y = 240
y = 24
Now plug in y back into the first equation
x = 45 - y
x = 45 - 24
x = 21

Today, Thurber studies math for 15 minutes and he studies science for 75 minutes. From now on, Thurber
plans to study math for 50 minutes per day and to study science for 30 minutes per day. Will Thurber ever
have studied the same total amount of time for both math and science? Explain. Use the drop-down
menus to complete the sentence.
Answer:
Given:
Today, he studies 15 minutes math and 75 minutes science
and from now on, 50 minutes math and 30 minutes science
Step-by-step explanation:
so if he studies for 1 day total time for math and science will be
math=15+50 science=75+30
=65 minutes =105 minutes
2nd day,
math=65+50 science=105+30
=115 minutes =135 minutes
3rd day,
math=115+50 science=135+30
=165 minutes =165 minutes
So, after three days Thurber will have studied the same total amount of time for both math and science and the time is 165 minutes for both.
In this exercise we have to use interpretation skills to calculate the total time that studied the two subjects:
[tex]165 \ both \ subjects[/tex]
Today, he studies 15 minutes math and 75 minutes science and from now on, 50 minutes math and 30 minutes science. So if he studies for 1 day total time for math and science will be:
Math: [tex]15+50 = 65[/tex] Science: [tex]75+30= 105[/tex]
2nd day:
Math: [tex]65+50 = 115[/tex] Science: [tex]105+30 = 135[/tex]
3rd day:
Math: [tex]115+50= 165[/tex] Science: [tex]135+30= 165[/tex]
So, after three days Thurber will have studied the same total amount of time for both math and science and the time is 165 minutes for both.

Mr.Travelswell is about to visit Germany and Sweden. He has £5000 to spend. He wants to exchange 60% of this into Euros in Germany, and the rest into Krona in Sweden. When he changes his £5000, 1 Euro = £0.75 and £1=12.63 Krona. Calculate how many Euros and how many Krona he will receive.
answer:
4000 Euros and 25260 kronas.
detailed answer:
If £5000 is 100percent of his money, then 60percent is £X
x=(60×5000)/100= 3000(£)
rest of it is £2000
lets calculate Euros first:
3000/0.75=4000 (Euro €)
now kronas:
2000×12.63=25260 krona.
Rewrite the rational function g(x)=x−4x in the form g(x)=c+rx, where c and r are constants.
Answer: g(x) = 0+(-3)x
Step-by-step explanation:
Given Function : g(x)=x−4x
To rewrite the above function g(x) in the form g(x)=c+rx, where c and r are constants.
Consider g(x)=x−4x = x(1-4)
⇒g(x) = -3x
⇒g(x) = 0+(-3)x
Here c = 0 , r =-3
Hence , the solution is g(x) = 0+(-3)x.
A function can be rewritten in several ways.
[tex]\mathbf{g(x) = x - 4x}[/tex] in form of [tex]\mathbf{g(x) = c + rx}[/tex] is [tex]\mathbf{g(x) = 0 - 3x}[/tex]
The function is given as:
[tex]\mathbf{g(x) = x - 4x}[/tex]
Evaluate like terms
[tex]\mathbf{g(x) = - 3x}[/tex]
Add 0 to the function
[tex]\mathbf{g(x) = 0 - 3x}[/tex]
Rewrite as:
[tex]\mathbf{g(x) = 0 + (- 3x)}[/tex]
Compare the above function to: [tex]\mathbf{g(x) = c + rx}[/tex];
We have:
[tex]\mathbf{c = 0}\\\\\mathbf{r = -3}[/tex]
Hence, [tex]\mathbf{g(x) = x - 4x}[/tex] in form of [tex]\mathbf{g(x) = c + rx}[/tex] is [tex]\mathbf{g(x) = 0 - 3x}[/tex]
