What is the volume of the sphere in terms on pie?
(Answer only with correct answers no links)

Answers

Answer:

The answer is A.

Step-by-step explanation:

Formula = 4/3pir^3

Diameter = 3

Radius = 3/2 = 1.5

Using the formula

1.5^3 = 3.375

3.375 * 4/3 = 4.5

Volume = 4.5 pi yd^3

The area of a rectangle is 8w + 18 square feet. The length of the rectangle is 2 feet. Use factoring to write an expression to represent the width of the rectangle.

Answers

Answer:

The expression that represents the width of the rectangle is 4w + 9

Step-by-step explanation:

The formula of the area of the rectangle is A= length x width

The area of a rectangle is 8w+18 square feet.

A= 8w+18

The HCF of 8 and 18 is 2

Divide each term of the area by 2 to get 2 as a common factor

8 /2 =4 and 18 /2 = 9

A=2(4w+9)

The length of the rectangle is 2 feet

Substitute it in the formula of the area above

A=2 x width

A=2 width

Equate the two right sides of the area

2 width =2(4w+9)

Divide both sides by 2

The width = 4w+9

Find the missing side lengths.

Here is how we can approach this problem in a step by step solution:

Look at what we are given - we know that the triangle is a right triangle (has a square on one of its angles representing 90 degrees), and the hypotenuse (the side opposite 90 degree angle) is 2 units long, and one of the other angles is 45 degreesUsing this information about angle measurements, we can solve for the third angle using the sum of angles in a triangle equals 180 degrees theorem: 180 - 90 - 45 = 45. After solving, we get that the final angle is 45 degreesNow, we know that the angles of the triangle are 90, 45, and 45 degrees. Using the base angle theorem, we know that his triangle must be an isocoles right triangleThat means that both legs of the triangle must be congruent (x = y)Finally, we can use the Pythagorean theorem because this is a right triangle to solve for the missing sides 4 = x^2 + y^2, 4 = 2 + 2, x = sqrt (2) y = sqrt (2)

*Also, if you knew that a 45-45-90 triangle's sides form a ratio of a, a, and sqrt (2) a, you could also use that and substitute in the values to solve. Both ways work! Hope this helps!!

Solve y=f(x) for x. Then find the input when the output is −3. f(x)=−7x−2 x= The input is when the output is −3.

Answers

Answer:

The input is 1/7

Step-by-step explanation:

If y =f(x)

Given that f(x) = -7x -2, then y = -7x-2

x is the input

y is the output

Given the output y = -3, we are to find the input value x

Recall that y = -7x-2

On substituting the value of y into the equation

-3 = -7x - 2

-7x = -3+2

-7x = -1

x = -1/-7

x = 1/7

Hence the input is 1/7

Solve the quadratic equation by factoring.
4x² - 20x + 28 = 3

A) x = 5
B) x = 5/2
C) x = 2/5
D) x = - 5/2

Answers

Answer:

B)  x = 5/2

Step-by-step explanation:

subtract 3 from each side to get:

4x² - 20x + 25 = 0

this is the difference of 2 squares:

(2x -5)² = 0

one solution, x = 5/2

Answer:

B)  x = 5/2

Step-by-step explanation:

4x² - 20x + 28 = 3

Move terms to the left side

4x² - 20x + 28 - 3 = 0

Subtract the numbers

4x² - 20x + 25 = 0

Use the quadratic formula

[tex]x =\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex]

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

4x² - 20x + 25 = 0

a = 4

b = -20

c = 25

x = [tex]\frac{-(-20)+\sqrt{(-20)^{2}-4x4x25 } }{2x4}[/tex]

Evaluate the exponent

x = [tex]\frac{20+\sqrt{400-4x4x25 } }{2x4}[/tex]

Multiply the numbers

x = [tex]\frac{20+\sqrt{400-400 } }{2x4}[/tex]

Subtract the numbers

x = [tex]\frac{20+\sqrt{0} }{2x4}[/tex]

Evaluate the square root

x = [tex]\frac{20+0 }{2x4}[/tex]

Add zero

x = 20 / 2 x 4

Multiply the numbers

x = 20 / 8

Cancel terms that are in both the numerator and denominator

x = 5/2
