Answer:

[tex](x + 1)^2 + (y-8)^2 = 173[/tex]

Step-by-step explanation:

[tex]\textsf{The standard form of the equation of a circle is }\\\\ \sf (x -h)^2 + (y-k)^2 = r^2 \;where\; (h, k) \textsf{ are the coordinates of the center of the circle and \;r\; is the radius}[/tex]

Here h = -1, k = 8

So we get
[tex](x - (-1)) ^2 + (y - 8)^2 = r^2[/tex]

[tex](x + 1)^2 + (y - 8)^2= r^2\\\\[/tex]

Since the circle passes through the point (-3, -5) we can plug in these values of x = -3 and y = -5 to get r squared

[tex](-3 + 1)^2 + (-5 -8)^2 = r^2\\\\(-2)^2 + (-13)^2 = r^2\\\\4 + 169 = r^2\\\\r^2 = 173\\\\\\[/tex]

So the equation of the circle is
[tex](x + 1)^2 + (y-8)^2 = 173[/tex]

Answer: Is the absolute difference if a is a positive number, when a = any rational number.

Step-by-step explanation:

Define Positive numbers:

Positive numbers are the numbers which are greater than zero that lies on the right side of the number line.

Example: 0, 1, 2, 3, 4…

Define Negative numbers:

Negative numbers are the numbers which are less than zero that lies on the left side of the number line.

Example: … -5, -4, -3, -2, -1, 0.

Given data,

Let a = any rational number. Is the absolute difference if a is a positive number.

Because,

Let us take,     a  =  any rational number

We have to know → Is the absolute value of a different if a is a positive number or negative number.

Define Modulus (|x|) of a number :

The modulus or absolute value of a number means the distance that goes from the number to its origin, this is, to the point 0 (zero) that makes part of the real straight line. For instance, the distance from point 6 to its origins is 6, but the distance from point -6 to its origins is also 6.

The modulus operator formula is :

             |x|  = { x if x ≥ 0     and     -x if x ≤ 0

Given question,

Assume any rational number   x/y

Using the Modulus property :

                |x|   = { x/y if x/y ≥ 0    and      -x/y if x/y ≤ 0

Therefore, if the rational number is less then zero (say -2).

Then the absolute value will be = - (- 2) = 2

and for any rational number greater than 0 (say 2)

Then its absolute value will be = 2 only.

Hence,

Is the absolute difference if a is a positive number, when a = any rational number.

The equation in terms of x that represents the given relationship is (7 + x)x = 555

The given parameters are

Length = L

Width = x

Area = 555 yd^2

From the question, we have

L = 7 + x

The area of a rectangle is

A = Lx

Substitute 7 + x for L

So, we have

A = (7 + x)x

Substitute 555 for A

So, we have

Recalling that SAT scores are always expressed as multiples of 10, then the points we get on the test will be 628.

In statistics, Standard deviation is a measure of the variation of a set of values.

σ = standard deviation of population

N = number of observation of population

X = mean

μ = population mean

WE have been given that SAT scores are normally distributed, with a mean of 500 points and a standard deviation of 100 points.

The solution as follows;

Let be X: scores of SAT

P(X ≥ x) = 0.9

P((X - 500)/100 ≥ (x - 500)/100) = 0.9

P(Z ≥ z) = 0.9

z = 1.28

1.28 = (x - 500)/100

128 + 500 = x

x = 628

Recalling that SAT scores are always expressed as multiples of 10, then the points we get on the test will be 628.

From the given discrete probability distribution, we have that:

a) Because the sum of all probabilities is of 1, we can verify that this is a probability model.

b) P(3 or 4) = 0.229.

c) P(at least one) = 0.908.

d) P(4) = 0.035.

e) Since both P(X ≤ 4) and P(X ≥ 4) > 0.05, 4 is not an unusual event.

The probability distribution in this problem gives the probability of a household having a number of TV sets, given as follows:

For item a, we have to add all the probabilities, hence:

0.092 + 0.275 + 0.101 + 0.194 + 0.035 + 0.303 = 1.

Because the sum of all probabilities is of 1, we can verify that this is a probability model.

For item b, we take the probabilities from the table as follows:

P(3 or 4) = P(X = 3) + P(X = 4) = 0.194 + 0.035 = 0.229.

For item c, we follow a similar procedure to item b, taking the probabilities from the table as follows:

P(at least one) = 1 - P(X = 0) = 1 - 0.092 = 0.908.

For item d, from the table, we have that:

P(4) = 0.035.

For item e, we have that:

Since both P(X ≤ 4) and P(X ≥ 4) > 0.05, 4 is not an unusual event.

The distinction between present value and future value is that the former is required now and the latter is needed at a future period

What is the difference between present value and future value?

The present value indicates today's worth or dollars of a future value  of a  flow whereas the future value determines the future worth of an investment or deposit made today or deposits over a number of years at a time in the future

The amount that Claudia would have in a year's time is future value because the present value is the initial deposit made today

The amount that Steven would  have to deposit today in order to accumulate $400,000 in 15 years is the present value

The amount that a deposit of $4,500 made today would worth in 6 years is the future value because the initial deposit is the present value.

Answer:

Step-by-step explanation:

The coordinates of C are (a,b).

You find the midpoint by taking the averages of the coordinates.

The general expression for the slope of the tangent line is m = y'(x) = 4x + 2. the value of m is - 10 for x = - 3 and is 4 for x = 0.5.

A line that only touches a curve once is said to be tangent to it. The point (x₀ , y₀) where a line with the equation of a tangent to a curve

y = f ( x ) is given by:

T' (x) = f'(x) (x ₋ x₀)  ₊ y₀

The slope of the tangent line to a curve at a point is computed by getting the first derivative of the curve.

y(x)=2x²y

y'(x) = (2)2x²⁻¹ ₊ (1)2x¹⁻¹

y'(x) = 4x¹ ₊ 2x°

y'(x) = 4x ₊ 2(1)

y'(x) = 4x ₊ 2

The slope at a point

P (x, y) is computed by substituting the x-coordinate of the point to the first derivative. This is the general expression for the slope:

m = y'(x) = 4x + 2

For x = - 3

m = 4 (- 3) + 2

m = - 12 + 2

m = - 10

For x = 0.5

m = 4 (0.5) + 2

m = 2 + 2

m = 4

Therefore, the general expression for the slope of the tangent line is m = y'(x) = 4x + 2. the value of m is - 10 for x = - 3 and is 4 for x = 0.5.
