What is the ordered pair of M after point M (5,6) is rotated 90 clockwise

All real numbers.

[tex]\boxed{TRUE}[/tex]

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

Expand: 4(a+2)=4a+8

Expand again: 14-2(3-2a)=4a+8

4a+8=4a+8

You subtract by 8 from both sides of an equation.

4a+8-8=4a+8-8

Simplify.

4a=4a

Then, subtract by 4a from both sides of an equation.

4a-4a=4a-4a

Finally, simplify.

4a-4a=0

0=0

True

All real numbers is the final answer.

Hope this helps you!

Answer:

Exponential growth is called growth because its curve increases really fast, so that's the main characteristic of exponential growth. I'm attaching an example of a function with exponential growth, which is the change of population size over time.

Answer:

25 m

Step-by-step explanation:

Use the Pythagorean Theorem.

a^2+b^2=c^2

Or just know you are finding the hypotenuse and use c=sqrt(a^2+b^2)

If you were finding a leg use a=sqrt(c^2-b^2).

So sqrt(15^2+20^2)

=sqrt(225+400)

=sqrt(625)

=25

ANSWER

[tex]y = 2x - 8[/tex]

EXPLANATION

To find the equation of a straight line, we need the slope and a point on that line.

We were given the equation of another line that will help us determine the slope . The given line has equation:

[tex]y = 2x + 4[/tex]

This equation is of the form

[tex]y = mx + b[/tex]

where

[tex]m = 2 \: \: is \: the \: \: slope.[/tex]

Since our line of interest is parallel to this line, their slopes are the same.

The line also contains the point (3,-2).

So we substitute the slope and point into the slope-intercept formula:

[tex] - 2= 2(3)+ b[/tex]

[tex] - 2 =6 + b[/tex]

[tex] \implies \: b = - 2 - 6 = - 8[/tex]

The required equation is

[tex]y = 2x - 8[/tex]

Final answer:

The equation of a line parallel to y = 2x + 4 and passing through the point (3, −2) is y = 2x − 8.

Explanation:

To find the equation of a line parallel to line AB with the equation y = 2x + 4 that passes through the point (3, −2), we need to use the fact that parallel lines have the same slope. Line AB has a slope of 2, so our new line will also have a slope of 2. Now, we use the point-slope form of a line: y − y1 = m(x − x1), where (x1, y1) is the point the line passes through and m is the slope. Substituting our point and slope in, we get y − (−2) = 2(x − 3). Simplifying, we get y + 2 = 2x − 6, and after moving the 2 to the other side, the final equation in slope-intercept form is y = 2x − 8.

The coordinates of the point A before dilation is (-12,-12)

Answer:

x = 6

Step-by-step explanation:

Given the 2 equations

x - y = 4 → (1)

x + y = 8 → (2)

Adding the 2 equations term by term eliminates the y- term

(x + x) + (- y + y) = (4 + 8), that is

2x = 12 ( divide both sides by 2 )

x = 6

Answer:

length=1.05m

perimeter=2.7m

Step-by-step explanation:

18900 in m^2=1.89 m^2

area=length*width

1.89=length*1.8 m

length=1.89÷1.8

length=1.05 m

perimeter=(l+w) 2

perimeter=(1.05+1.8)2

perimeter=2.85×2

perimeter=2.7 m

a. The rectangular backboard’s length in meters is 1.05 meters.

b. The perimeter of the total area in meters is 5.7 meters.

Given the following data:

Conversion:

10,000 [tex]cm^{2}[/tex] = 1 [tex]m^2[/tex]

18,900 [tex]cm^{2}[/tex] = X [tex]m^2[/tex]

Cross-multiplying, we have:

[tex]X = \frac{18900}{10000}[/tex]

X = 1.89 [tex]m^2[/tex]

a. To find the backboard’s length in meters:

Mathematically, the area of a rectangle is given by the formula;

[tex]A = LW\\\\1.89 = L(1.8)\\\\L = \frac{1.89}{1.8}[/tex]

Length, L = 1.05 meters.

b. To find the perimeter of the total area in meters:

Mathematically, the perimeter of a rectangle is given by the formula;

[tex]Perimeter = 2(L+W)[/tex]

Substituting the values into the formula, we have;

[tex]Perimeter = 2(1.05+1.8)\\\\Perimeter = 2(2.85)[/tex]

Perimeter = 5.7 meters

Answer:

C = 58.88 degrees

Step-by-step explanation:

We can use the law of cosines to find the missing angle measurement

c^2 = a^2 +b^2 -2ab cosC

Rearranging and solving for cos C

2ab Cos C = a^2 +b^2 - c^2

Divide by 2ab

cos(C) =  a^2 + b^2 − c^2

             ------------------------

                         2ab

Substituting what we know  a = 31 b = 21   c = 27

                            31^2 + 21^2 - 27^2

     cos C        =  -----------------------------

                             2(31)(21)

      cos C = .516897081

Take the inverse cos on each side

cos^-1 cos C = cos ^-1 (.516897081)

C = 58.88 degrees

Answer:

The reflected point is (3,6)

Step-by-step explanation:

we know that

The reflection Ry = 5, means a reflection is across the line y= 5

we have

the point P(3,4)

Since the point P has y-coordinate  4, its distance to the line y= 5 is equal to 1 units (P is located 1 units down the line y=5).

therefore

The reflection of the y-coordinate will be 1 units above the line y=5, which is  equal to

5+1=6

Hence

the y-coordinate of the image is 6.

The reflected point is (3,6)

To reflect a point about the y-axis, negate the x-coordinate while keeping the y-coordinate the same.

In this question, you are given the point P(3,4) and asked to find Ry=5(P). The notation Ry=5(P) represents the reflection of point P about the y-axis. To reflect a point about the y-axis, you need to replace the x-coordinate with its opposite (negate it) while keeping the y-coordinate the same.

So, P(3,4) reflected about the y-axis becomes (-3,4). The x-coordinate changes from 3 to -3, but the y-coordinate remains the same at 4.

Therefore, Ry=5(P) is (-3,4).

The next step is to add (b/2a)^2 to both sides to complete the square, then balance the equation by adding the inverse of that value outside the parentheses.

The student has asked for the next step in solving the quadratic equation 0 = −2x2 + 2x + 3 by completing the square.

After rewriting the equation and factoring out the coefficient of the x2 term, the next step is to add a specific value to both sides to form a perfect square trinomial.

This value is found by taking (b/2a)2, where a is the coefficient of x2 and b is the coefficient of x. For this equation, we therefore add −(2/2*(-2))2 = 1 to both sides inside the parentheses.

The completed equation becomes −3 + 1 = −2*(x2 − x + 1/4). Finally, we must balance the equation by adding the inverse of −<strong>2*1/4</strong> outside the parentheses.

Then, we can continue solving for x.

Step-by-step explanation:

You are welcome.

The expressions (x-5)/(x+3) and 4/(x-3) can be rewritten with a common denominator of (x+3)(x-3) to become ((x-5)(x-3))/((x+3)(x-3)) and 4(x+3)/((x+3)(x-3)).

The expressions stated are: (x-5)/(x+3) and 4/(x-3). In order to rewrite these expressions with a common denominator, you need to multiply the denominators together to create a common denominator. Therefore, the common denominator would be (x+3)(x-3).

Next, each expression must be rewritten so that they have this common denominator. For the first expression, we multiply the numerator and denominator by (x-3) so we get: ((x-5)(x-3))/((x+3)(x-3)).

For the second expression, we multiply the numerator and denominator by (x+3) so we get: 4(x+3)/((x+3)(x-3)). So, the expressions rewritten with a common denominator are ((x-5)(x-3))/((x+3)(x-3)) and 4(x+3)/((x+3)(x-3)).

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠QRT is an exterior angle of the triangle

∠RTS and ∠RST are the 2 opposite interior angles, thus

45x = 25x + 57 + x

45x = 26x + 57 ( subtract 26x from both sides )

19x = 57 ( divide both sides by 19 )

0.5 + 0.5 + 0.5 + 0.5 = 2

Answer:

The oven mitts cost

$13.80

But, Cook-n-Serve buys from a wholesaler, so they receive a discount of 40%

This means that they pay

(1-0.4)*($13.80) = 0.6*($13.80) = $8.28 for each pair

The markup rate on cost is 60%

And they sell for

$13.80/$8.28 = 1.67 times the price

1.67*100% = 167%

The markup rate on selling price is  167%

Answer:

d.no change

Step-by-step explanation:

There will be no change in the quantity of products sold.

Option D will be the correct answer.

Given that the turnover is increased by 10 % when the price increases by 10 %.

Let us consider that the price of the product is x and the quantity sold is n numbers. Then the turnover t will be given as,

[tex]t = x\times n[/tex]

An increase in the price of the product is 10 % results in an increase in turnover by 10%. Hence the increased price is,

[tex]x' = x+\dfrac{10}{100}\times x[/tex]

[tex]x' = 1.1 x[/tex]

Hence new turnover will be,

[tex]t'= x\times n + \dfrac {10}{100} \times x\times n[/tex]

[tex]t'= 1.1\times x\times n[/tex]

The quantity sold can be calculated by dividing the new turnover by the increased price of the product. Thus, the new quantity of the product will be,

[tex]n' = \dfrac {t'}{x'}[/tex]

[tex]n' = \dfrac {1.1\times x\times n}{1.1\times x}[/tex]

[tex]n' =n[/tex]

We can see that the quantity of the product sold remains unchanged.

Hence option D will be the correct answer, there will be no change in the quantity of product sold.

Answer:

0.009 units in the positive y direction.

Step-by-step explanation:

Vertical shift is simply the value of the constant.

In this case, if you expand the formula by multiplying 0.9 into the parentheses,

y = 0.9 sin [(π/3) - x] + (0.9)(0.01)

y = 0.9 sin [(π/3) - x] + 0.009

Here the value of the constant is 0.009 and it is positive, hence the vertical shift is 0.009 units in the positive y direction.

Answer:

[tex]\frac{\sqrt[4]{3x^2} }{2y}[/tex]

Step-by-step explanation:

We can simplify the expression under the root first.

Remember to use  [tex]\frac{a^x}{a^y}=a^{x-y}[/tex]

Thus, we have:

[tex]\sqrt[4]{\frac{24x^{6}y}{128x^{4}y^{5}}} \\=\sqrt[4]{\frac{3x^{2}}{16y^{4}}}[/tex]

We know 4th root can be written as "to the power 1/4th". Then we can use the property  [tex](ab)^{x}=a^x b^x[/tex]

So we have:

[tex]\sqrt[4]{\frac{3x^{2}}{16y^{4}}} \\=(\frac{3x^{2}}{16y^{4}})^{\frac{1}{4}}\\=\frac{3^{\frac{1}{4}}x^{\frac{1}{2}}}{2y}\\=\frac{\sqrt[4]{3x^2} }{2y}[/tex]

Answer:

1152

Step-by-step explanation:

First we need to find the area of the wall in square inches

8 ft = 8*12 = 96 inch tall

36 ft = 36 * 12 = 432 inches wide

The area = 96 * 432 =41472 in^2

Each ounce of paint cover 72 in^2 so divide by 72

41472/72 =576

We need 576 ounces to cover the wall

At 2 dollars per ounces

576*2 =1152 dollars to paint the wall

[tex]y=2^{\left(x-2\right)}+3[/tex]

To solve this problem, we need to start with the parent function of the exponential function, which is [tex]f(x)=a^x[/tex], where [tex]a[/tex] is the base. In our problem, [tex]a=2[/tex], so our parent function here is [tex]y=2^x[/tex]. Then, we need to perform some transformations to our parent function. Thus:

1. Vertical shrink:

A vertical shrink is a nonrigid transformation because the graph of the function get a distortion in the shape, so this transformation is as follows:

[tex]g(x)=cf(x)[/tex]

where [tex]c[/tex] in this problem equals 0.25 because:

[tex]y=0.25(2^x) \\ \\ y=\frac{1}{4}(2^x) \\ \\ y=\frac{2^x}{2^2} \\ \\ y=2^{(x-2)}[/tex]

2. Vertical shift:

The graph of the function [tex]y=2^{(x-2)}[/tex] get a vertical shift given by:

[tex]y=2^{(x-2)}+3[/tex]

So the graph is shifted 3 units up. So the result is the graph shown above.
