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%

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.

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:

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]

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.

This is a question from coordinate geometry. This is a very simple question. You can solve it by using distance formula.

‎ ‎ ‎ ‎ ‎ ‎

First we have to assume the coordinates as following:-

Let the coordinates of A be (8,4) and coordinates of B be (5,1).

‎ ‎ ‎ ‎ ‎ ‎

Further we have to assume:-

[tex] \mapsto\sf{X_1=8}[/tex]

‎ ‎ ‎ ‎ ‎ ‎

[tex]\mapsto \sf{Y_2=1}[/tex]

Here we have distance formula:-

[tex] \sf{Distance \: of \: AB= \sqrt{({X_2-X_1) }^{2} + {( Y_2-Y_1) }^{2} } }[/tex]

‎ ‎ ‎ ‎ ‎ ‎

[tex] \sf{Distance \: of \: AB= \sqrt{({5 - 8) }^{2} + {( 4 - 1) }^{2} } }[/tex]

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

Step-by-step explanation:

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,  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:

2nd day:  

3rd day:  

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.

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]
