The answer is

The distance from the point (x,y) to the focus, (−2,3), is (x + 2)^2+(y − 3)^2. The distance from the point (x,y) to the directrix, y=7, is |y−7|.

Find the circumference of each circle. Use 3.14 for the value of π . Round answer to the nearest tenth.

kvv77 [185]

Answer:

$C=9.4\pi$ meters

Step-by-step explanation:

Recall to find the circumference of a circle the formula is $C=\pi d$ or $C=2\pi r$ .

We start by substituting 4.7m for r in the second circumference formula.

$C=2\pi r\\C=2\pi (4.7)\\C=9.4\pi$ . We input this value of r into the area formula.

I don't know how to solve this

sergiy2304 [10]

The answer that I got was side WX = 12 inches

It says that WY is congruent to XY which means that they are the same. That means that XY is also 3m-4. It also says that the perimeter of the triangle is 76 inches.

With this information I set up an equation:

3m-4 + 3m-4 +m = 76

(The number on the right side is the perimeter given to us in the problem and the numbers on the left side are the 3 side lengths).

I combined like terms on the left side and ended up with:

7m-8=76

I added 8 to both sides of the equation and got 7m=84.

Finally I divided both sides by 7 and got m=12

m is equivalent to side WX..

Hope this helps!

A mutual fund company offers its customers a variety of funds: a money-market fund, three different bond funds (short, intermedi

bagirrra123 [75]

Answer:

a. 7% probability that the selected individual owns shares in the balanced fund.

b. 31% probability that the individual owns shares in a bond fund.

c. 58% probability that the selected individual does not own shares in a stock fund

Step-by-step explanation:

a. What is the probability that the selected individual owns shares in the balanced fund?

7% of the individuals owns shares in the balanced fund, so 7% probability that the selected individual owns shares in the balanced fund.

b. What is the probability that the individual owns shares in a bond fund?

Bond funds (short, intermediate, and long-term):

15%(short-term) + 11%(intermediate-term) + 5%(long-term)

15%+11%+5% = 31%

31% probability that the individual owns shares in a bond fund.

c. What is the probability that the selected individual does not own shares in a stock fund?

Anything but moderate and high risk stock%.

The sum of all probabilities is 100%.

18% + 24% = 42% own stock fund.

100 - 42 = 58%

58% probability that the selected individual does not own shares in a stock fund
