Given,

Cylinder A has a volume of 6 cubic units

and height =3 units

The radius of cylinder A,

\begin{gathered} r=\sqrt[]{\frac{V}{\pi h}} \\ =\sqrt[]{\frac{6}{3\pi}} \\ =0.8 \end{gathered}

To find the volume of a cylinder B

\begin{gathered} V=\pi r^2h \\ =(3.14)\times(0.8)^2\times(3) \\ =6.03 \end{gathered}

Thus the volume of cylinder B is 6.03

Sara is trying to find an equation for a line that passes through (5, 2) and is perpendicular to 3x + 2y = 15. Explain the steps
Anettt [7]
Not on your list, but an easy way is
.. a) swap coefficients of x and y, negating one. (Now you have 2x -3y.)
.. b) set any constant term to zero (now you have 2x -3y = 0)
.. c) translate the line to the point (5, 2) by substituting x ⇒ x-5, y⇒ y-2
2(x -5) -3(y -2) = 0


The way you've been taught, selection C is the proper choice.

Find the distance between the points (-1,-2) and (5,2). Simplified radical form.
frozen [14]

Answer:

2\sqrt{13}

Step-by-step explanation:

Using the distance formula,

\sqrt{( x_{2}-x_{1} )^2+(y_{2} -y_{1})^2 }

We just need to plug in the numbers.

So \sqrt{(-1-5)^2+(-2-2)^2}

Then we simplify it to

\sqrt{(-6)^2+(-4)^2} , to \sqrt{36+16}

Finally, we get

\sqrt{52}, which is 2\sqrt{13} when simplified.

A start-up company opened with 8 employees.
tiny-mole [99]

By representing the equation is written in the form y = ax + b .

The value of b is 8.

According to the question

A start-up company opened with 8 employees.

So, Number of employees = 8

At zero quarter = 8

The company’s growth plan assumes that 2 new employees will be hired each quarter

After 1 quarter = Number of employees + 2 new employees

After one quarter = 8 + 2 = 10

Equation is written in the form y = ax + b to represent the number of employees, y, employed by the company x quarters after the company opened

y = ax  + b

10 = 2 × 1 + b

10 = 2 + b

Subtract 2 on both sides of the equation

b = 10 - 2

b = 8

The value of b is 8.
