The equation of a circle is given by:

where (h, k) = center of the circle

r = radius of the circle

The center of a circle is the midpoint of the endpoints of the diameter of the circle. Hence, to find the center of the circle, we have to find the midpoint of the diameter:

where (x1, y1) and (x2, y2) are the endpoints of the diameter.

Hence, the center of the circle is:

To find the radius of the circle, we have to find the distance between any endpoint of the circle and the center of the circle.

To do this apply the formula for distance between two points:

Therefore, the radius of the circle is:

Hence, the equation of the circle is:

Step 1 : Let's review the information given to us to answer the problem correctly:

• Annual salary of the governor of New York = $ 1,790,000

• Annual salary of the governor of Tennessee = $ 940,000

Step 2: Let x to represent the annual salary of the governor of New York

and let's find the ratio of the salary of the governor of Tennessee, as follows:

940,000/1,790,000 = 0.525

Step 3: Now, let's write the equation for calculating the salary of the governor of Tennessee for any given year, this way:

• 0.525x = Annual salary of the governor of Tennessee

•

Step 4: If the salary of the governor of New York for the next year is 2,000,000, then we can calculate the salary of the governor of Tennessee, this way:

0.525x = 0.525 * 2,000,000 = 1,050,000

The annual salary of the governor of Tennessee woudl be 1,050,000

And then add it to the original price:

Since it's a price, we have to round this result to the nearest hundredth

Answer:

The new price is $23.09

Answer:

The first option is correct

Explanation:

Two negatives makes a positive.

The x intercept is the value of x when y = 0

Given that x intercept = - 1, the coordinate is (- 1, - 0)

The y intercept is the value of y when x = 0

Given that y intercept = - 2, the coordinate is (0, - 2)

Slope = (y2 - y1)/(x2 - x1)

x1 = - 1, y1 = 0

x2 = 0, y2 = - 2

Slope = (- 2 - 0)/(0 - - 1)

slope = - 2/1

slope = - 2

the length of a rectangle is 11 yd more than twice the width and the area of the rectangle is 63 yd squared. find the dimensions of the rectangle.​

Let

L ------> the lenght

W ----> the width

we know that

the area of rectangle is

A=L*W

A=63 yd2

63=L*W -------> equation 1

and

L=2W+11 ------> equation 2

substitute equation 2 in equation 1

63=(2W+11)*w

2W^2+11w-63=0

solve the quadratic equation using the formula

a=2

b=11

c=-63

substitute

the solutions for W are

w=3.5 and w=-9 (is not a solution, because is negative)

so

Find the value of L

L=2W+11 -------> L=2(3.5)+11

L=18

therefore

the dimensions are

A proportional relationship is one in which two quantities vary directly with each other. We say the variable y varies directly as x if:

y = kx

for some constant k , called the constant of proportionality . This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

From the given options, the baove property is satisfied by,

Thus, the correct option is A.

The slope intercept form of a line can be expressed as,

Here, m is the slope of the line and c is the y intercept.

Comparing the above equation with the given equation of a line y=-5x+2, we get

m=-5.

The slope of a line perpendicular to line with slope m is -1/m.

Hence, the slope of line perpendicular to y=-5x+2 is,

The new line is given to be passing through point with coordinates (x1, y1)=(3, -1).

The point slope form of a line passing through point with coordinates (x1, y1)=(3, -1) and having slope m1 is,

Therefore, the slope-intercept form of the equation of the line perpendicular to y = -5x + 2 and passing through (3,-1) is,

To detrmine the formula of the polynomial, we check for the roots on the graph:

when y = 0, x = -2

when y = 0, x = 4

We have two roots.

x = -2

x + 2 = 0

x = 4

x - 4 = 0

3rd factor is x = 0

Hence, we have two factors: x(x + 2) and (x - 4)

The polynomial function using the factors:

Next, we find the value of a:

To get a , we pick a point on the graph. let the point be (0, -4)

substitute the point in the function above:

The formula of the polynomial becomes:

Given,

The coordinates of the point is (-8, 0).

To find the solution of the system by graphing we need to plot each line in the plane and look for the intersection.

First we need to write both equations in terms of y:

now we need to find two points for each of this lines. To do this we give values to the variable x and find y.

For the equation 2x-y=-1, if x=0 then:

so we have the point (0,1).

If x=1, then:

so we have the point (1,3).

Now we plot this points on the plane and join them with a straight line.

Now we look for two points of the second equation.

If x=0, then:

so we have the point (0,-3)

If x=1, then:

so we have the point (1,-1).

We plot the points and join them wiith a line, then we have:

once we have both lines in the plane we look for the intersection. In this case we notice that the lines are parallel; this means that they wont intersect.

Therefore the system of equations has no solutions.

Inverse proportionality is when the value of one quantity increases with respect to a decrease in another, they behave opposite in nature.

It is represented by the following expression:

Since P=24 when Q=3, we can substitute and solve for the constant k:

Then, the equation that represents the inverse variation would be:

The initial price is $38.21, and it got an increase of 7%, so the new price is the old one multiplied by 1.07:

Then, the new price decreased by 7%, so let's multiply it by 0.93 (that is, 1 minus 0.07):

So the price in August is $38.02.

Solution

- The first integral is bounded by the x-values of [6, 22]

- The second integral is bounded by the x-values of [6, 14]

- When we are asked to find the difference between the two integrals, since, they both begin at 6, it implies that, when the second integral is taken away from the first integral, there must be some extra x-values.

- The extra values are from 14 to 22.

- Thus, we have:

The unitary method is a technique used to determine the value of a single unit from the value of many units and the value of multiple units from the value of a single unit. We typically utilize it for math calculations. This approach will come in handy for topics involving ratio and proportion, algebra, geometry, etc. In the unitary technique, we always count the value of a unit or one quantity first before figuring out the values of more or fewer quantities. This method is referred to as the "unitary method" for this purpose.

There are two types of unitary methods because they result in two types of variations and those are given below:

Given from the number line:

D = -2 and F = 13

So, the distance DF = 13 - (-2) = 13 + 2 = 15

1) find E such that, DE : EF = 2 : 1

so,

so, x : (15 - x) = 2 : 1

x = 30 - 2x

3x = 30

x = 10

So, E = -2 + 10 = 8

=========================================================================

2) E is 4/5 of the distance from F to D

So, the distance from F = 4/5 * 15 = 12

So, E = 13 - 12 = 1

=====================================================================

3) the ratio of DE : EF = 2 : 3

So,

3x = 2 ( 15 - x)

3x = 30 - 2x

5x = 30

x = 30/5 = 6

E = -2 + 6 = 4

=================================================

4) E is 1/3 of the distance from D to F

So, the distance DE = 1/3 * 15 = 5

So, E = -2 + 5 = 3

=====================================================

As a summery:

1) E = 8

2) E = 1

3) E = 4

4) E = 3

What is area of rectangle?

Rectangle is a four sided figure whose parallel sides are equal and whose every angle is 90°

The total space taken by the rectangle is called area of the rectangle.
