[tex](h-p))(y) = -y^3-3y^2+7y+5[/tex]

Step-by-step explanation:

Given

[tex]h(y) = -3y^2+5\\p(y) = y^3-7y[/tex]

We have to find the difference of two functions given

So,

[tex](h-p)(y) = h(y) - p(y)\\= (-3y^2+5)-(y^3-7y)\\=-3y^2+5-y^3+7y\\=-y^3-3y^2+7y+5[/tex]

Hence,

[tex](h-p))(y) = -y^3-3y^2+7y+5[/tex]

Answer:

Y equals three x minus two

Final answer:

The equation y = 3x - 2 represents a line with a slope of 3 and a y-intercept of -2.

Explanation:

The equation y = 3x - 2 represents a line in the Cartesian coordinate system. This equation follows the slope-intercept form y = mx + b, where m is the slope of the line and b is the y-intercept. In this case, the slope (m) is 3, meaning that for every one unit increase in x, y increases by 3 units.

The y-intercept (b) is -2, indicating that the line crosses the y-axis at the point (0, -2). To find an equation for a line given a point and a slope, you can use the point-slope form, y - y1 = m(x - x1). With the point (-7, 1) and slope 3, the equation is y - 1 = 3(x + 7).

Answer:

3003 number of 5-member chess teams can be chosen from 15 interested players.

Step-by-step explanation:

Given:

Number of the interested players =  15

To Find:

Number of 5-member chess teams that can be chosen = ?

Solution:

Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula[tex]nCr = \frac{n!}{r!(n - r)!}[/tex]

where

n represents the total number of items,

r represents the number of items being chosen at a time.

Now  we have n = 15 and r = 5

Substituting the values,

[tex]15C_5 = \frac{15!}{5!(15- 5)!}[/tex]

[tex]15C_5 = \frac{15!}{5!(10)!}[/tex]

[tex]15C_5 = \frac{15!}{5!(10)!}[/tex]

[tex]15C_5 = \frac{15\times \times 14 \times 13 \times 12 \times 11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1 }{5 \times 4 \times 3 \times 2 \times 1(10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3 \times 2 \times 1)}[/tex]

[tex]15C_5 = \frac{15\times \times 14 \times 13 \times 12 \times 11}{(5 \times 4 \times 3 \times 2 \times 1)}[/tex]

[tex]15C_5 = \frac{360360}{120}[/tex]

[tex]15C_5 = 3003 [/tex]

The width of rectangle is 6.

Step-by-step explanation:

Given,

Area of rectangle; w²+4w=60

As w is the width, we will solve the equation to find w.

[tex]w^2+4w=60[/tex]

Subtracting 60 from both sides

[tex]w^2+4w-60=0[/tex]

Factorizing the equation;

[tex]w^2+10w-6w-60=0\\w(w+10)-6(w+10)=0\\(w+10)(w-6)=0[/tex]

Either,

w+10=0         => w=-10

Or,

w-6=0           =>w=6

As width cannot be negative, therefore

Width = 6

The width of rectangle is 6.

7*20*12=1680

Answer: x = -5

Step-by-step explanation: To solve this equation, we start by distributing the -4 through the parentheses on the left side.

So we have -4 times x which is -20x and -4 times -5 which is positive 20. So our equation now reads -20x + 20 = 120.

Solving from here, we subtract 20 from both sides of the equation and we have -20x = 100 and dividing both sides by -20, we find that x = -5.

Although I will not provide work to check our answer, the great thing about solving equations is that your can always check your answer by substituting what you got as a final answer into the original equation.

Answer:

Step-by-step explanation:

R = report length

R = 40 + (3/8)R + (1/3)R

3/8 = 3*3/8*3 = 9/24

1/3 = 8*1 / 3*8 = 8/34

R = 40 + (9/24)R + (8/24)R

R = 40 + (17/24)R                         Subtract 17/24 from the left

R-17/24 R = 40

7/24 R = 40                                  Multiply both sides by 24

7R = 40 * 24

7R = 960                                       Divide by 7

R  = 960/7

R = 137.1 which breaks the rounding rule and becomes 138 because something has to be typed on page 138

Answer:

The total price of the meal after tax and tip is $31.62.

Step-by-step explanation:

Given:

Their bill is = $25.40.

Sales tax = 5.5%.

Tip to waitress = 18%.

Now, to find the total price of the meal after tax and tip.

So, to get the price of the meal after sales tax :

$25.40 + 5.5% of $25.40.

[tex]=25.40+\frac{5.5}{100} \times 25.40.[/tex]

[tex]=25.40+\frac{139.70}{100}[/tex]

[tex]=25.40+1.397=\$26.797[/tex]

Now, to get the total price after tax and tip:

$26.797 + 18% of $26.797.

[tex]=26.797+\frac{18}{100} \times 26.797[/tex]

[tex]=26.797+0.18\times 26.797[/tex]

[tex]=26.797+4.823[/tex]

[tex]=\$31.62.[/tex]

Therefore, the total price of the meal after tax and tip is $31.62.

Answer:

18

Step-by-step explanation:

Find the equation for the line in slope-intercept form: y = mx + b.

x and y are points on the line. Points are written in the form (x, y).

m is the slope.

b is the y-intercept, when it hits the y-axis.

Substitute the point (4, 4) and slope. x = 4; y = 4; m = -2. Find b

y = mx + b

4 = (-2)(4) + b

4 = -8 + b

b = 4 + 8

b = 12

Get the equation of the line using slope and the y-intercept.

y = -2x + 12

Substitute -3 as x and find the missing y.

y = -2(-3) + 12

y = 6 + 12

y = 18

The point was (-3, 18)

Therefore the missing value for y is 18.

To find the y-value, you substitute the given points into the formula for slope and solve for 'y'. In this case, the required value of 'y' is 18.

The subject of your question is mathematics, specifically the concept of calculating the slope of a line. The slope (m) of the line through two points (x1,y1) and (x2,y2) is defined as m = (y2 - y1) / (x2 - x1). You are given that the points are (4,4) and (-3,y) and the slope is -2. Substituting the given points into the formula gives -2 = (y - 4) / (-3 - 4 ). Solving this equation will give you the value of 'y'.

First, simplify the denominator to get -2 = (y - 4) / -7. Afterward, multiply both sides by -7 to eliminate the fraction: -2 * -7 = (y - 4). This yields 14 = y - 4. Solve for 'y' by adding 4 to both sides of the equation, which gives that y = 18.

Answer:

[tex] |60| = | - 60| [/tex]

Step-by-step explanation:

They are equal. When the negative sign is inside the box the absolute value is positive, when the negative sign is outside the box THEN it is negative.

Answer: equal to

Step-by-step explanation: Absolute value means distance from zero on a number line. To represent the absolute value of a number, we use a vertical bar on either side of the number like we see in this problem.

So for the absolute value of 60, we know that 60 is 60 units from zero on a number line which means that the absolute value of 60 is just 60.

For the absolute value of -60, we know that -60 is also 60 units from zero on the number line so the absolute value of -60 is also 60.

Now we know that the absolute value of -60 is 60 and the absolute value of 60 is also 60. Since 60 is the same as 60, it means that 60 is equal to 60.

Another way of thinking about absolute value is that no matter what number you have inside the absolute value, your result will always be positive except for 0 which has an absolute value of 0.

In other words, the absolute value of any number is the positive version of that number. Again, not including zero.

Final answer:

To calculate the force required, we use the formula F = k * (W / sqrt(V)) * (1 / d), where F is the force, W is the weight, V is the velocity, and d is the distance. We can find the constant of variation k by substituting the given values of F, W, V, and d into the formula. After finding k, we can plug in the new values of W, V, and d to calculate the force required.

Explanation:

To solve this problem, we can use the formula F = k * (W / sqrt(V)) * (1 / d), where F is the force, W is the weight, V is the velocity, and d is the distance.

First, we can calculate the constant of variation k by substituting the given values of F, W, V, and d into the formula. This gives us: 36 = k * (120 / sqrt(100)) * (1 / 50).

Solving for k, we get k = 36 * 100 * 50 / 120 = 1500.

Next, we can plug in the new values of W, V, and d into the formula and solve for F. Substituting W = 200, V = 256, and d = 800, we have: F = 1500 * (200 / sqrt(256)) * (1 / 800).

Simplifying further, we get F = 1500 * 200 / (16 * 800) = 18.75 Newtons.

Option A

It is a function because at any given time the oven was exactly one temperature.

Solution:

Given that,

At 5:00 p.m., Antonio turned on the oven

While the oven preheated, the temperature in the oven increased from 72°F to 400°F over a 10-minute period

The oven remained at 400°F for 45 minutes until Antonio turned it off

It took 60 minutes for the temperature in the oven to cool, returning to 72°F at 6:55 p.m

From above information,

5:00  ------------ 72°F

5:10 ------------------ 400°F

5:45 ------------------ 400ºF

6:55 -------------------- 72°F

Thus at any given time (input) the oven was exactly one temperature  (a single output )

Therefore the statement that best explains is:

Option A) It is a function because at any given time the oven was exactly one temperature.

Since the definition of function states that there is a unique image corresponding to a element hence here the temperature at a given time is unique

Answer:

Number of cheaper dresses sold  is 35

Number of expensive  dresses sold  is 15

Step-by-step explanation:

Given:

Cost of cheaper dresses = $90

Cost of  expensive dresses = $140

Total cost of  the dresses = $5250

To Find:

Number of cheaper dress = ?

Number of expensive  dress = ?

Solution:

Let

The number of  cheaper dresses be x

The number of  expensive dresses be y

(Number of cheaper dresses X cost of cheap dress) +  (Number of Expensive dresses X cost of  expensive dress)  =  $5250

[tex]x \times90 +y \times 140 = 5250[/tex]=  $5250

It is given that the 20 more of the cheaper dresses than the expensive dresses is sold

So,

number of cheaper dress  =  20  +  number of expensive dress

x = 20 + y---------------------------------------(1)

[tex](20+y) \times90 +y \times 140 = 5250 = 5250[/tex]

[tex](20 \times 90 +y\times 90) +y \times 140= 5250 [/tex]

Answer:

[tex]A'(-0.25,0.75)\\\\B'(1.75,-0.25)\\\\C'(-1,-0.25)[/tex]

Step-by-step explanation:

A Dilation is defined as  a transformation in which the image and the pre-image have the same shape, but their sizes are different.

When the scale factor is greater than 1, the image obtained after the  dilation is greater than the pre-image and it is an "Enlargement".

When the scale factor is is between 0 and 1,  the image obtained after the  dilation is smaller than the pre-image and it is an "Reduction".

In this case you know that the triangle ABC was dilated by this scale factor:

[tex]scale\ factor=\frac{1}{4}[/tex]

With the origin as the center of dilation.

Since:

[tex]0<\frac{1}{4}<1[/tex]

It is a Reduction.

You can identify that the vertices of the triangle ABC are:

[tex]A(-1,3)\\\\B(7,-1)\\\\C(-4,-1)[/tex]

So you need to multiply the coordinates of each vertex  of the triangle ABC by [tex]\frac{1}{4}[/tex], in order to get the coordinates of the triangle A'B'C. Then, you get:

[tex]A'=(\frac{1}{4}(-1),\frac{1}{4}(3))=(-0.25,0.75)\\\\B'(\frac{1}{4}(7),\frac{1}{4}(-1))=(1.75,-0.25)\\\\C'(\frac{1}{4}(-4),\frac{1}{4}(-1))=(-1,-0.25)[/tex]

The coordinates of the vertices of triangle A'B'C' include the following;

A' (-1/4, 3/4).

B' (7/4, -1/4).

C' (-1, -1/4).

In Mathematics and Euclidean Geometry, dilation is a type of transformation that is used for altering the dimensions of a geometric figure, but not its shape.

In this scenario and exercise, we would have to dilate the coordinates of the pre-image by using a scale factor of 1/4 centered at the origin as follows:

Ordered pair A (-1, 3) → (-1 × 1/4, 3 × 1/4) = Ordered pair A' (-1/4, 3/4).

Ordered pair B (7, -1) →  (7 × 1/4, -1 × 1/4) = Ordered pair B' (7/4, -1/4).

Ordered pair C (-4, -1) →  (-4 × 1/4, -1 × 1/4) = Ordered pair C' (-1, -1/4).

How far do you want to calculate the decimal places for the answer? Here are some examples:

   31 divided by 16 = 1.937500 calculating to 6 decimal places

   31 divided by 16 = 1.937 calculating to 3 decimal places

   22 divided by 15 = 1.466666666 calculating 9 decimal places

   22 divided by 15 = 1.466666 calculating 6 decimal places

   22 divided by 15 = 1.466 calculating to 3 decimal places

Note that this is not the same as rounding to a specific number of decimal places. For example, 22 divided by 15 = 1.466 when calculated to 3 decimal places because you stop once you reach the third decimal place. On the other hand, 22 divided by 15 = 1.467 when rounded to 3 decimal places. In order to round to the third decimal place you must calculate to at least the fourth decimal place so that you know how to round the third decimal place

Lo has 1 hour and 45 minutes between leaving work at 6:15 p.m. and meeting her friends at 8:00 p.m.

She needs  around 1/4 of an hour for each errand.

To find out how many errands she can run, we divide the total time available by the time required for each errand:

Convert 1 hour 45 minutes to minutes: 1 hour = 60 minutes, so 1 hour 45 minutes = 60 + 45 = 105 minutes.

Calculate how many errands she can run:  105/15 = 7.

Therefore, Lo has time to run 7 errands between work and dinner.

where a₁ is the first term and d the common difference

Here a₁ = 40 and d = - 6, thus

[tex]S_{15}[/tex] = [tex]\frac{15}{2}[/tex] [ (2 × 40) + (14 × - 6) ], that is

[tex]S_{15}[/tex] = 7.5(80 - 84) = 7.5 × - 4 = - 30
