5 0

Answer:

(x - 3)^{2} + (y + 4)^{2}  = 4

Step-by-step explanation:

Center is at (3, -4)  and the radius is 2

(x - 3)^{2} + (y + 4)^{2}  = 4

The volume of a cylinder can be expressed as V=πr2h, where r is the radius, and h is the height of the cylinder.
olga_2 [115]

<em>Note: You missed to add the answer choices, so I am solving the overall procedure to determine the radius of the cylinder so that you could easily figure out the right choice.</em>

Answer:

The radius of the cylinder:

  • r\:=\:\sqrt{\frac{v}{\pi \:h}}

Step-by-step explanation:

The volume of a cylinder is represented by the formula

V=πr²h

here

  • r is the radius
  • h is the height

The radius of the cylinder can be computed using the formula of the volume of a cylinder

V = πr²h

r² = V / πh

Taking square roots

r\:=\:\sqrt{\frac{v}{\pi \:h}}

Thus, the formula of the radius of the cylinder.

r\:=\:\sqrt{\frac{v}{\pi \:h}}

Therefore, the radius of the cylinder:

  • r\:=\:\sqrt{\frac{v}{\pi \:h}}

Which variable is discrete?
svetoff [14.1K]

We want to see which one of the given variables is a discrete variable, the correct option is "number of pockets inside jacket"

<h3>What is a discrete variable?</h3>

A discrete variable is a variable that can't take some values in a given interval where it is defined, in contrast to a continuous variable, which can take all the values of the interval.

For example, the "length of a jacket" would be considered a continuous variable, as the length can take any measure you want.

Similar for the weight and the size of the jacket pocket in square inches, these are continuous variables.

But the remaining option is not continue, the number of pockets inside the jacket can only be an integer, then there are values (like 1.3) that can't represent the number of pockets inside the jacket, thus, this is a discrete variable.

So the correct option is the first one: "number of pockets inside jacket"

If angle PQR and angle RQS form a linear pair and angle PQR =5x+5 and angle RQS =11x-65 then angle PQR=?
Mama L [17]

Answer:

m<PQR = 80°

Step-by-step explanation:

<u>Points to remember</u>

Sum angles in a linear pair is 180

<u>To find the value of x</u>

It is given that, angle PQR and angle RQS are linear pairs, and

m< PQR =5x+5 and m<RQS =11x-65

m<PQR + m<RQS = 180

5x + 5 + 11x - 65 = 180

16x -60 = 180

16x = 180 + 60

16x = 240

x = 15

<u>To find the value of angle PQR</u>

m<PQR = 5x + 5

 = 5*15 + 5

 = 75 + 5 = 80

Therefore m<PQR = 80°

How to round decimals to the nearest tenth
mr Goodwill [35]

Answer:

To round a number to the nearest tenth , look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.

Step-by-step explanation:
