What is the slope of the graph of y = 12x - 197

Answer:

The center is ( 5.3, -3.3) and 7 is the radius

Step-by-step explanation:

We can write the equation of a circle as

( x-h)^2 + ( y-k)^2 = r^2

Where ( h,k) is the center and r is the radius

(x - 5.3)^2 + (y + 3.3)^2=49

(x - 5.3)^2 + (y -  -3.3)^2=7^2

The center is ( 5.3, -3.3) and 7 is the radius

Answer:

The width is 16 cm

Step-by-step explanation:

The perimeter of a rectangle=28 cm

length=8cm

width=?

P=28

=L+W

=8+8=16

=6+6=12

=16+12

=28 cm

Therefore, the width is 6+6=16 cm

Hope it helps you!!

Answer: 12

Step-by-step explanation: the length is 8 cm so, times that by 2 because there are 2 lengths which makes it 16cm. Now you subtract 16 from the 28cm which is 12cm divide this by 2 because there are two widths this equals 6 cm

Therefore; our width is 6 cm

To check if this is right you can add all the values= 8+8+6+6= 28cm

Answer:

The interval over  which the cost is constant is from >0 to 15,000 gallons

The interval for which the the cost is increasing is from above 15,000 gallons

Step-by-step explanation:

For 15,000 gal or less the cost of the monthly water bill = $15.50

For over 15,000 gal, the cost of the monthly water bill = $15.50 plus $1 for each 1000 gal over 15,000 with any fraction of $1,000 charged at a fraction of $1

The interval for which the cost is constant is from 0 ≤ x ≤ 15,000 gal

The interval over which the const is increasing per 1000 gal over 15,000 gallons is from x > 15,000 gal.

Answer:

The interval in which the cost is constant is

[0,15000]

Step-by-step explanation:

4x - y = 5..........… Equation 1

x + 2y = 8 ............. Equation 2

Make x the subject in equation 2 and substitute it into equation 1

That's

x = 8 - 2y

We have

4( 8 - 2y ) - y = 5

32 - 8y - y = 5

- 9y = - 27

Divide both sides by - 9

We have the final answer as

Substitute y = 3 into x = 8 - 2y

That's

x = 8 - 2(3)

= 8 - 6

Hope this helps you

Step-by-step explanation:

4x-y=5-----×1.

x+2y=8----×4.

which will be....

4x-y=5

- 4x+8y=32.

____________

y=3.

then substitute into any equation...

equation one.

4x-3=5.

4x=5+3.

4x=8.

x=8/4.

x=2.

therefore y=3 and x=2.

Answer:

2 sqrt(5) =x

Step-by-step explanation:

We can use the Pythagorean theorem since this is a right triangle

a^2 + b^2 = c^2

2^2 +4^2 = x^2

4+16 = x^2

20 = x^2

Take the square root of each side

sqrt(20) = sqrt(x^2)

sqrt(4*5) = x

sqrt(4) sqrt(5) =x

2 sqrt(5) =x

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

Work Shown:

x = amount of money collected before tax is added

3% = 3/100 = 0.03

3% of x = 0.03x = amount of tax

x + 0.03x = adding on tax to original amount

1.03x = amount after tax is added

1.03x = 2766.58

x = 2766.58/1.03

x = 2686 is the amount of money before the 3% sales tax is added

0.03x = 0.03*2686 = 80.58 is the amount of sales tax collected

As a check,

2686+80.58 = 2766.58

which confirms our answer

Answer:

Tax collected= $80.58

Step-by-step explanation:

Let's say that the amount he got from services was "x", and to that he had to add a 3% of sales tax.

Recall that 3% in math form is written as: 3/100 = 0.03

then, he had to include 0.03 times x to the "x" amount in hotel services:

x + 0.03 x = 2766.58

1.03 x = 27688.58

x = 27688.58/1.03

x= $2686

Then, the amount for the taxes is 3% of this which is:

0.03 * 2686 = $80.58

Answer:

I prefer leaving the answer as √5 since it is a shorter form and exact form of the answer.

Here are reasons for leaving it as a radical form or a decimal approximation.

If you are looking for an exact answer, then you should leave it as √5. For example, if you are told a square has area 5 square units, then the exact length of the side is √5 units.

If √5 is the length of something that has to be made to that length, then you need an approximation. For example, if you are asked to make a square out of cardboard whose area is 5 square feet, then you need an approximation of √5 ft, such as 2.24 ft, so you can make each side of the cardboard square in the length of 2.24 ft.

We shall prefer to keep √5 in radical form, as it is an irrational number and will never give an exact value when converted to decimal form.

A rational number is any number that can be represented in the form p/q, where p and q are integers, q ≠ 0, and p, q are co-prime to each other, that is, they do not have any common factor except 1.

All terminating and non-terminating recurring decimals are rational numbers.

An irrational number is a real number that cannot be represented in the above form of a rational number.

All non-terminating non-recurring decimals are irrational numbers.

We are asked, what would we prefer to do. Leave √5 in radical form or convert it into decimal form.

∵ √5 is an irrational number, we will never get a perfect value of it in decimal form, as irrational numbers are non-terminating non-recurring decimals. So, we shall prefer to keep √5 in the radical form.

Use of √5 in radical form: Gives the exact value in our calculations for equations.

Use of √5 = 2.236067977499........... in the decimal form: Used in trigonometry where we need to find the trigonometric ratio.

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

Explanation:

See the diagram below. We're looking for the area of the shaded region in blue.

This is known as an inscribed circle since the circle is inside the square, touching each side at one point. This circle is as large as possible without spilling outside the square. Think of a balloon that has been inflated as much as possible to fill the room (it touches every wall at a tangent point).

The square has area s^2 = 6^2 = 6*6 = 36 square inches.

The circle has area pi*r^2 = pi*3^2 = 9pi square inches exactly. Note how I cut the diameter (6) in half to get the radius (3).

The blue shaded area is the difference of the square and circle areas, so we have 36 - 9pi as the exact area of the shaded region.

Using your calculator, you should find that 36-9pi = 7.72566611769187 approximately. I'm using my calculator's stored version of pi as opposed to something like pi = 3.14; but you may need to ask your teacher for clarification about what version of pi to use.

When rounding to the nearest tenth, we then get roughly 7.7 square inches as our final answer.

The surface area of the given right cylinder is 252π square units. Therefore, option D is the correct answer.

The surface area of a cylinder refers to the total area that the cylinder's curved surface and circular bases cover. The total surface area of the cylinder includes the area of the 2 bases of the cylinder (each of which is in the shape of a circle) and the area of the curved surface.

Given that, the radius of a cylinder is 6 units and the height of a cylinder is 15 units.

We know that, the total surface area of a cylinder is 2πr(r + h).

Now, the surface area = 2×π×6(6+15)

= 2×π×6×21

= 252π square units

Therefore, option D is the correct answer.

Simple Function question, if there’s an X with the same number, it’s not a function. It wasn’t D since it’s justifying the range being the same number

Hey there! I'm happy to help!

Let's call these numbers x and y and model the information we have.

x=1/5y

y-x=228 (we see that x is smaller than y in the first equation, so we put it second )

We see that x is equal to 1/5y. We can switch the x in the second equation with 1/5y and solve for y.

y-1/5y=228

4/5y=228

We divide both sides by 4/5.

y=285

We know that x is 1/5 of y, so we divide by 5.

285/5=57

x=57

So, our numbers are 57 and 285.

Have a wonderful day! :D

The 2 positive numbers are 285 and 57 and they have a difference of 228.

An equation is an expression used to show the relationship between two or more numbers and variables.

Answer:

end point ₂ of a segment  X₂ = - 22 ;  Y₂ = 29

Step-by-step explanation:

given;

midpoint = ( Mx = - 15 , My = 22 )

endpoint ₁  = ( X₁ = - 8 ,  Y₁ = 15 )

find the other endpoint ₂ ( X₂ , Y₂)

use the mid point formula to get the other endpoint:

Mx = ( X₁ + X₂ ) / 2              My = ( Y₁ + Y₂ ) / 2

- 15 = (-8 + X₂) / 2                 22 = (15 + Y₂) / 2

-30 = - 8 + X₂                         44 = 15 + Y₂

X₂ = -22                                    Y₂ = 29

Answer:

So, the formula for finding the midpoint of a segment given the coordinates of its endpoints is: ((x 1 + x2)/2, (y 1 + y 2 )/2 {Average of the x coordinates, average of the y coordinates}. For this problem we know the coordinates of the midpoint along with one of the endpoints.

Step-by-step explanation:

Use the midpoint formula

M = (  (x1 + x2) / 2  ,  (y1 + y2) / 2 )

(9, 0) = (  (x1 + 12) / 2  ,   (y1 + 3) / 2)

Break up this formula into two equations.

(x1 + 12) / 2 = 9   and (y1 + 3) / 2 = 0

 Solve for x1 and y1 from the equations.
