center (-4, -7), tangent to x = 2

Answers

Answer:

(x + 4)^2 + (y + 7)^2 = 36

Step-by-step explanation:

The given information describes a circle with its center at (-4, -7) and tangent to the vertical line x = 2. To determine the radius of the circle, we need to find the distance between the center and the tangent line.

The distance between a point (x1, y1) and a line Ax + By + C = 0 is given by:

d = |Ax1 + By1 + C| / sqrt(A^2 + B^2)

In this case, the equation of the line is x = 2, which can be written as 1x + 0y - 2 = 0. Therefore, A = 1, B = 0, and C = -2. The center of the circle is (-4, -7), so x1 = -4 and y1 = -7. Substituting these values into the formula, we get:

d = |1*(-4) + 0*(-7) - 2| / sqrt(1^2 + 0^2)

d = |-6| / sqrt(1)

d = 6

Therefore, the radius of the circle is 6 units. The equation of a circle with center (h,k) and radius r is given by:

(x - h)^2 + (y - k)^2 = r^2

Substituting the values we have found, we get:

(x + 4)^2 + (y + 7)^2 = 36

This is the equation of the circle that satisfies the given conditions.

Victoria bought a dress on 40% discount, and saved a massive $60. How much did the dress cost originally? How much did she pay for it?

Answers

Answer:

Answer: Original price = $150   Amount Paid = $90

Step-by-step explanation:

First we make a proportion 60/x = 40/100. When we cross multiply and divided to get x by itself we get $150 dollars. This is the original price of the dress. Now we take $150-$60 and we get $90. This is what Victoria paid for the dress after the 40% discount.

when its comes to interest,most CDs will allow which of the following options?
a. Unlimited withdraws of interest
b. Periodic interest payout
c. loans against principal
d. Withdrawal of principal

Answers

When it comes to interest, most Certificates of Deposit (CDs) will allow periodic interest payouts. So, correct option is B.

A CD is a type of savings account that allows you to earn a fixed interest rate on your deposit for a specific period of time, called the term. Typically, the longer the term of the CD, the higher the interest rate offered.

However, during the term of the CD, the funds are locked in, meaning that you cannot withdraw the principal without incurring a penalty.

While some CDs may allow for unlimited withdrawals of interest, this is not common, and may still come with restrictions or penalties. Loans against principal are also not typically allowed with CDs, as the funds are meant to be held for a set term.

Therefore, the most common option available for CD holders is to receive periodic interest payouts, which can be monthly, quarterly, or annually, depending on the terms of the CD. This allows the CD holder to earn interest on their deposit while still receiving some income during the term of the CD.

So, correct option is B.

Write the standard form of the equation of the circle center (0,4) passes through the point (-2,-4)

Answers

\(▪▪▪▪▪▪▪▪▪▪▪▪▪  {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪\)

As we know, the standard form of circle is written in this way ~

\( \qquad \sf x{}^{2} + y {}^{2} + 2gx + 2fy + c = 0\)

where, the coordinates of centre is (-g , -f) and radius equals to :

\(\qquad \sf  \dashrightarrow \: \sqrt{g {}^{2} + {f}^{2} - c } \)

Now, it's time to equate the coordinates of centre ~

\( \qquad \sf( - g, - f) \: \: and \: \: (0,4)\)

Here we get,

\(\qquad \sf  \dashrightarrow \: - g = 0\)

\(\qquad \sf  \dashrightarrow \: g = 0\)

and

\(\qquad \sf  \dashrightarrow \: - f = 4\)

\(\qquad \sf  \dashrightarrow \: f = - 4\)

Now, let's find the the Radius using distance formula on the given points, one of them is centre and other is point lying on circle, so distance between them is the radius.

\(\qquad \sf  \dashrightarrow \: r = \sqrt{( 0 - ( - 2)) {}^{2} + (4 - ( - 4)) {}^{2} }\)

\(\qquad \sf  \dashrightarrow \: r = \sqrt{ (0 + 2) {}^{2} + (4 + 4) {}^{2} } \)

\(\qquad \sf  \dashrightarrow \: r = \sqrt{ (2) {}^{2} + (8) {}^{2} } \)

\(\qquad \sf  \dashrightarrow \: r = \sqrt{ 4+ 64 } \)

\(\qquad \sf  \dashrightarrow \: r = \sqrt{ 68 } \)

\(\qquad \sf  \dashrightarrow \: r = 2\sqrt{ 17 } \)

Now, use the the following equation to find c of the standard equation

\(\qquad \sf  \dashrightarrow \: r = \sqrt{g {}^{2} + {f}^{2} - c} \)

\(\qquad \sf  \dashrightarrow \: 2 \sqrt{17} = \sqrt{ {0}^{2} + {4}^{2} - c}\)

squaring both sides :

\(\qquad \sf  \dashrightarrow \: 68 = {0}^{2} + {4}^{2} - c\)

\(\qquad \sf  \dashrightarrow \: 68 = 8 - c\)

\(\qquad \sf  \dashrightarrow \: - c = 68 - 8\)

\(\qquad \sf  \dashrightarrow \: c = - 60\)

Therefore, we got the standard equation of circle as ~

\(\qquad \sf  \dashrightarrow \: {x}^{2} + {y}^{2} + 2(0)x + 2( - 4)y + ( - 60) = 0\)

\(\qquad \sf  \dashrightarrow \: {x}^{2} + {y}^{2} - 8y - 60 = 0\)

A line segment known as a perpendicular bisector divides a straight line segment into two congruent or equal segments. At the exact midpoint of the line segment, they divide it. The arcs with the same radius from each endpoint is important as this makes the arcs parallel.

subtract 14 from both sided to get x alone,

What is the mean for the combined set if both the samples have n=5? b. What is the mean for the combined set if the first sample has n=5 and the second sample had n=35?

Answers

Answer:

a. M = 50

b. M = 242

Step-by-step explanation:

mean =  \(\frac{sum of scores}{number of samples}\)

⇒ sum of scores = mean x number of samples

Let the mean be represented by M, and the number of samples be represented by n,

sum of scores = M x n

a. When n = 5 for both samples,

The first sample's sum of scores = M x n

                                     = 7.2 x 5

                                     = 36

The second sample's sum of scores = M x n

                                     = 12.8 x 5

                                     = 64

The mean for the sum of scores of the combined set = \(\frac{36 + 64}{2}\)

                                     = 50

When both samples have n = 5, the mean of the combined set is 50.

b. When the first sample has n = 5, the sum of scores = 36.

If n = 35 for the second sample, the sum of scores = M x n

                                                          = 12.8 x 35

                                                          = 448

The mean for the sum of scores of the combined set = \(\frac{36 + 448}{2}\)

Number of males = 60

Number of stated preferred to snowboard = 45

Number of females preferred to ski = 22

Based on the above information, the relative frequency male preferred to ski is

Before computing this first we have to calculate the number of ski picked which is

= Number of males - Number of stated preferred to snowboard

= 60 - 45

= 15

Now the relative frequency is
