Answer:

1,350 students

Step-by-step explanation:

The number of students this year is 90% of the number from last year.  Find 90% of 1500....

90% is 0.9 as a decimal,

0.9(1500) = 1,350 students

Answer: 2i50 students

Step-by-step explanation:

Do 90% of 1,500

10% = 150

150 x 9 = 1350

We need the total amount of students

So do 1350 + 1500 = 2850 students

Replace x in each equation with 4:

f(x) = x^2 +2x-3 = 4^2 + 2(4) -3 = 16 + 8 -3 = 21

g(x) = x^2-9 = 4^2 -9 = 16-9 =7

Now you have values for f(x) and g(x) now you can solve for f/g and f+g:

f/g = 21 / 7 = 3

f+g = 21 + 7 = 28

For this case, we have that by definition:

[tex](f + g) (x) = f (x) + g (x)\\(\frac {f} {g})(x) = \frac {f (x)} {g (x)}[/tex]

We have the following functions:

[tex]f (x) = x ^ 2 + 2x-3\\g (x) = x ^ 2-9[/tex]

So:

[tex](f + g) (x) = x ^ 2 + 2x-3 (x ^ 2-9)\\(f + g) (x) = x ^ 2 + 2x-3 x ^ 2-9\\(f + g) (x) = 2x ^ 2 + 2x-12\\(f + g) (4) = 2 (4) ^ 2 + 2 (4) -12\\(f + g) (4) = 2 * 16 + 8-12\\(f + g) = 32 + 8-12\\(f + g) (4) = 28[/tex]

On the other hand:

[tex](\frac {f (x)} {g (x)}) = \frac {x ^ 2 + 2x-3} {x ^ 2-9}\\Evaluated\ at\ x = 4[/tex]

[tex](\frac {f (x)} {g (x)}) = \frac {4 ^ 2 + 2 (4) -3} {4 ^ 2-9} = \frac {16 + 8-3} {16 -9} = \frac {21} {7} = 3[/tex]

Answer:

[tex](f + g) (4) = 28\\(\frac {f} {g}(4)) = 3[/tex]

Step-by-step explanation:

Answer:

$3116

Step-by-step explanation:

First off, we need to find the value of the appliance after the down payment.

$2450 - $600 = $1850

This then makes our principal $1850.

P = $1850

r = 9% or 0.09

t = 4 years

To find the total cost of the appliance plus interest, we need to look for our accrued amount first.

A = P + Prt

A = $1850 + $1850(0.09)(4)

A = $1850 + $666

A = $2516

Now that we know our accrued amount, we then add our down payment to find the total cost.

Total cost = $2516 + $600

Total cost = $3116

To calculate the cost of an appliance with added interest, subtract the down payment from the purchase price to determine the amount of the loan. This is followed by the calculation of the total interest over the length of the loan. Adding these two amounts provides the total cost of the appliance plus interest, which in this case is $2516.

The total cost of the appliance plus interest can be calculated by first determining the amount of the loan made, which is the cost of the appliance minus the down payment. This comes out to $2450 - $600 = $1850.

Then, the add-on interest over 4 years is calculated by multiplying the amount of the loan by the annual interest rate and by the number of years. For this question, that is $1850 * 0.09 * 4 = $666.

So, the total cost of the appliance with interest added is the sum of the amount of the loan and the amount of the interest. Therefore, $1850 + $666 = $2516 is the total cost for the appliance plus interest.

Answer:

The Field's length is 93ft

Step-by-step explanation:

P=2L+2w

360=2(w+6)+2w

360=2w+12+2w

360=4w+12

348=4w

348/4=w

87=w

L=w+6

L=87+6

L=93

The width of a rectangular field surrounded by 360 feet of fencing is 87 feet. The length of the field, which is 6 feet more than the width, is 93 feet.

We are dealing with a rectangular field here, and we know that the length of a rectangle is equal to the total fencing (perimeter), divided by two, minus the width. Now, the problem states that the length is 6 feet more than the width. Therefore, we can create the following equation: 2x + 2(x + 6) = 360, where x is the width.

After simplifying this equation, we find that 4x + 12 = 360. Subtract 12 from both sides to get 4x = 348, and then divide by 4 to find that x = 87 feet. Thus, the width of the field is 87 feet. Since the length is 6 feet more than the width, we add 6 to 87 to get a length of 93 feet.

Answer:

A and B

Step-by-step explanation:

When rotating a point (or any shape around a certain point), none of the diameters of the shape will change. So for example, with this circle, when you rotate it around a point, the radius and circumference will not change because it has just rotated. It wont be on the x-axis though because point P is not on the x-axis an it is being rotated 180 degrees about point P. Just know that when you are rotating, nothing about the shape changes, all angles or measurements will be the same, it is just moving to a different place.

Step-by-step explanation:

The equation of the line in slope-intercept form, is:

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

Where m is the slope and b is the y-intercept.

By definition, parallel lines have the same slope.

Then:

- Find the slope of the the line that connects the points (-7,3) and (-6,1), as following:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{1-3}{-6-(-7)}=-2[/tex]

- We know that the other line is connected with the point (-4,5), therefore, you can substitute values and solve for b:

[tex]5=-2(-4)+b\\5=8+b\\5-8=b\\b=-3[/tex]

Then, the equation for the line containing the side opposite the side containing the first two vertices is:

The answer is -|x-4|.

Answer:y=-|x-4|

Step-by-step explanation:

we know the graph of y=|x| touches at x=0 and opens upward towards y axis

but this graph is facing downwards therefore it should be of form

y=-|x|

but it touches the x axis at x=4

therefore the graph is represented by

y=-|x-4|

4 is added inside the mod because it intersect x axis at x=4

The graph would be y=-|x-4|+1 if it shifts 1 unit upwards.

The means is 8.5 The Median is 6

Step-by-step explanation:

1) to find the mean just Simply add all the numbers together and divided by how many numbers that is giving. (Because you are simply finding the average)

9+6+5+3+28+6+4+7=68

68 divided by 8 = 8.5

2) to find the median simply organize the numbers from least to greatest Like this: (3,4,5,6,6,7,9,28) Then keep crossing out from both sides teal you find the middle Number.

If there a odd amount of number the median will be one Number, if even 2 numbers ( if 2 numbers just add them both and divide by 2)

In This Case the Median is 6,6 but Its actually 6 Why (6+6=12) and (12/2=6) so your median is 6.

The mean of the given data 9, 6, 5, 3, 28, 6, 4, 7 is 8.5 and the median is 6.

The mean is defined as the average of all the values or the mean can be defined as the sum of all observations by the total number of observations.

[tex]Mean =\dfrac {\ Sum \ of \ all \ observation}{Total \ number \ of \ observation}[/tex]

[tex]Mean = \dfrac{9 + 6 + 5 + 3 + 28 + 6 + 4 + 7}{8}[/tex]

Mean = [tex]\dfrac{68}{8}[/tex]

Mean  = 8.5

Therefore, the mean of the data set is 8.5.

The median is defined as:

The median is the middle value when the data set is arranged in ascending or descending order.

If there are two middle values, the median is the average of those two values.

Arrange the data set in ascending order: 3, 4, 5, 6, 6, 7, 9, 28.

Here n = 8, since n is even so the median is calculated as:

Median = [tex]\dfrac{(\dfrac{n}{2}) \ th \ observation + (\dfrac{n}{2}+1) \ th \ observation}{2}[/tex]

Median =[tex]\dfrac{( 4 \ th \ observation + 5 \ th \ observation)}{2}[/tex]

The 4th observation is 6 and the 5th observation is 6.

So, this mean will be 6.

Therefore, the median of the data set is 6.

The Mean is  8.5 and the median is  6.

The lengths of the legs of each triangle are:

1) Leg = √19

2) Leg = √105

3) Leg = √60

How to use Pythagoras Theorem?

Pythagoras Theorem is defined as the way in which you can find the missing length of a right angled triangle.

The triangle has three sides, the hypotenuse (which is always the longest), Opposite (which doesn't touch the hypotenuse) and the adjacent (which is between the opposite and the hypotenuse).

Pythagoras is in the form of;

a² + b² = c²

a = √(c² - b²)

1) We are given that:

Hypotenuse = 10

Opposite side = 9

Thus, using Pythagoras Theorem, we have:

Leg = √(10²- 9²)

Leg = √19

2) We are given that:

Hypotenuse = 19

Opposite side = 16

Thus, using Pythagoras Theorem, we have:

Leg = √(19²- 16²)

Leg = √105

3) We are given that:

Hypotenuse = 8

Opposite side = 2

Using Pythagoras Theorem, we have:

Leg = √(8²- 2²)

Leg = √60

My life is not linear. Time is not constant. My life (and time included) is just a series of times that do not run parallel to each other. Instead, they drift further or closer as a function of velocity and curvature of space time.

Answer: If you are looking for a linear equation in your life, an example could be the rate of the grass growing in your lawn. The y axis could be the height and the x axis could be the time. As it grows, the line representing the grass could go up gradually; when you cut it, the line can stop. Keep doing that for however long you'd like to represent the grass growing/getting cut.
