Answer:

59.11221 in^3/s

Step-by-step explanation:

Given dr/dt = 0.6 in/s

Find dV/dt when r = 2.8 in.

[tex]V=\frac{4\pi r^3}{3}\\[/tex]

so [tex]\frac{dV}{dr}=4\pi r^2\\[/tex]

[tex]\frac{dV}{dt}=\frac{dV}{dr}\cdot\frac{dr}{dt}=4\pi r^2\cdot\frac{dr}{dt}[/tex]

Use r = 2.8 in and dr/dt = 0.6 in/s

get

[tex]\frac{dV}{dt}=59.11221 in^3/s[/tex]

Answer:

(x - 2)² + (y - 6)² = 49

Step-by-step explanation:

Equation of a circle formula:  (x - a)² + (y - b)² = r²

where (a, b) is the center of the circle and r is the radius

Given, center = (2, 6) and radius = 7

Substitute this information in the equation of a circle formula.

⇒ Equation of the circle:  (x - 2)² + (y - 6)² = 49

8.  11/12 gallons of paint
10. 23/24 gallons of drink mix

Step-by-step explanation:

Note: When denominators are different, you must find a common denominator between the two fractions by multiplying both values
Ex: 1/3 and 1/4 = 4/12 and 3/12 common denominator is 12

8. Find the common denominator, 3/4 and 1/6, multiple the first denominator, 4, with three to get 12. Now multiply the numerator by the same number. 9/12 is our new fraction. Since the new denominator is 12, we have to get the other denominator to be 12 as well. Multiply 6 from 1/6 by 2 to get 12. Now do the same with the numerator. 2/12 is our new fraction, and all that's left is to add them together to find how much paint Damon has in total, which is 11/12 gallons.

10. Same concept as the above, 1/12 and 7/8 have a common denominator of 24, multiply 1 and 12 by two to get 2 and 24. Multiply 7 and 8 by 3 to get 21 and 24. 2/24 and 21/24 are our new fractions to add together. 23/24 is our answer.

Step-by-step explanation:

25 + 9³ = 25 + 81 = 106

remember, the cube of a number means to multiply it with itself 3 times (for a squared number that would be 2 times).

9³ = 9×9×9

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division

The value of the expression 25 + 9³ is 754.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The sum of 25 and the cube of 9.

This can be written as,

Answer:

13.5 and 7

Step-by-step explanation:

x + y = 20.5

× - y = 6.5

Hence,

x =20.5 - y

20.5 - 2y = 6.5

Hence,

2y = 14

and x = 20.5 - 20.5 - 7 = 13.5

Hope that helps :))

Answer:

The two numbers are 7 and 13.5

Step-by-step explanation:

Let the two numbers be x and y

Make 3 equations (for system of equation and substitution method)

Equation 1. x - y = 6.5

Equation 2. x = 6.5 + y

Equation 3. x + y = 20.5

Use the value of x in equation 2 to substitute x in equation 3.

6.5 + y + y = 20.5

Combine like terms

6.5 + 2y = 20.5

- 6.5 on both sides

2y = 14

Divide both sides by 2 to isolate y

y = 7

Substitute y in equation 3 to find x

x + 7 = 20.5

x = 13.5

Hope this helps :)

Answer:

5x^2-8x + 12

Step-by-step explanation:

the formula for finding roots of equation is

x^2- (sum of roots)x + products of roots =0

and we already have the roots of the equation

so we add them to give 8

and multiply to give 12

hence the quadratic equation that has those roots with leading coefficient is 5x^2-8x + 12=0

Answer:

The electron moved down to an energy level and has an energy of

[tex]10.92 \times 10^{-19} \textsf{J}[/tex]

Step-by-step explanation:

[tex]\textsf{initial energy level of electron}= 16.32 \times 10^{-19} \textsf{J}[/tex]

[tex]\triangle E =\textsf{energy released}= 5.4 \times 10^{-19} \textsf{J}[/tex]

A positive energy change means that the electron absorbs energy, while a negative energy change implies a release of energy from the electron.

Therefore, when an electron absorbs energy, the electron moves up to higher energy levels, and when an electron releases energy, it moves to lower energy levels.

[tex]\triangle E=E_2-E_1[/tex]

[tex]\implies 5.4 \times 10^{-19} = 16.32 \times 10^{-19} -E_1[/tex]

[tex]\implies E_1= 16.32 \times 10^{-19} -5.4 \times 10^{-19}[/tex]

[tex]\implies E_1= 10.92 \times 10^{-19}[/tex]

Answer:

The electron moved down to an energy level and has an energy of
