PLEASE HELP!!! I do not understand!!!

Answer:

c = [tex]\sqrt{90}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse c is equal to the sum of the squares on the other 2 sides, that is

c² = 9² + 3² = 81 + 9 = 90 ( take the square root of both sides )

c = [tex]\sqrt{90}[/tex]

Answer:

[tex]y = 120 + 0.15x[/tex]

Step-by-step explanation:

Given

[tex]Additional\ Fee = \$0.15[/tex] per vertical meter

[tex]y = fee[/tex] per x meter

[tex]x = vertical\ meter[/tex]

For:

[tex]x = 3500[/tex] --- [tex]y = 645[/tex]

Required

Determine the equation that relates y to x

Let the initial fee be represented with m

The equation that relates y to x is:

[tex]y = Initial\ Fee + Additional\ Fee * Vertical\ Meter[/tex]

This gives

[tex]y = m + 0.15 * x[/tex]

We need to first solve for m

From the question,

[tex]x = 3500[/tex] when [tex]y = 645[/tex]

So:

[tex]645 = m + 0.15 * 3500[/tex]

[tex]645 = m + 525[/tex]

Make m the subject

[tex]m = 645 - 525[/tex]

[tex]m = 120[/tex]

So, the initial fee is $120

Substitute 120 for m in [tex]y = m + 0.15 * x[/tex]

[tex]y = 120 + 0.15 * x[/tex]

[tex]y = 120 + 0.15x[/tex]

Hence, the required equation is: [tex]y = 120 + 0.15x[/tex]

Answer: Whats True about 2 angles and 7 anglesis that They are not the same number and one of them is less and great

Answer:

yes

Answer:

1

Step-by-step explanation:

The exponent is the number of times you multiply the base aka i in this case.

i = -1

Substitute -1 for i.

-1^2

-1 x -1 = 1

because when you multiply two negatives they make a positive.

Answer:

11

Step-by-step explanation:

36/4 = 9

9 = x-2

x = 11

Step-by-step explanation:

Perimeter = 36

length = x - 2

Perimeter of a square = 4 × length

36 = 4(x - 2)

dividing through by 4:

9 = x - 2

hence:

x = 9 + 2 = 11.

Answer:

as always, the rate of change is ∆y/∆x. In this case, that's

(127-95)/(3-1) = 16

Step-by-step explanation:

Answer:

use rise over run! this means  "rise" (being the change in y, going up or down) divided by the "run" (being the change in x, going from left to the right).

Answer:

Y= -1/3 |x+3| +5

Step-by-step explanation:

An absolute value will always make a V line.

In your particular problem it wants you to reflect it over the x axis, and to do this you simply need to place a negative.

A negative in the beginning of the problem is only there to say whether you flip your line or not, and this means you don't have to worry about it any more.

What it looks like so far: Y= -

Next it wants you to compress the line vertically by 1/3

A number that causes your line to compress is always less than one

A number that stretches your line would be 1 or more

This number is always placed right next to the left of the parenthesis or absolute value.

What it looks like so far: Y= - 1/3

Now we want the line to move left 3 units.

We are now inside of the absolute value because this is where we move the line left or right. This can get a little confusing, but once you get it then you don't forget it.

Inside the line.. a -# moves right and a +# moves left.

This number should be placed inside the absolute value and to the right of the x.

What it should look like: Y= - 1/3 |x + 3|

Now they want us to move the line up by 5 points.

To the outer right side of the absolute value is where we move things up or down.

To move a number up you need to place a + sign with however many places it wants you to move to the right of the sign, but to move the line down you need to place a - sign with however many places it wants you to move to the right of the sign.

To move this up you simply need to place a +5 to the outer right side of the absolute value.

What you should end up with: Y= - 1/3 |x+3| +5

El símbolo de grado no se usa para informar la temperatura usando la escala Kelvin, sino que se indican como Kelvin. El agua hierve a 100 grados Celsius o 212 grados Fahrenheit, o 373,15 Kelvins. El agua se congela a 0 grados Celsius o 32 grados Fahrenheit, o 273,15 Kelvins. El cero absoluto es 0 Kelvin.

Answer:

3 Ohms

Step-by-step explanation:

U1 = 5 ohm × 1.5 amps = 7.5 V

U2 = U - U1 = 12 - 7.5 = 4.5 V

R2 = U2 / I = 4.5 / 1.5 = 3 Ohms

Answer:

20 more of her friends prefer FortNite than Among Us

Step-by-step explanation:

Lynne was wondering which game was more popular so she aksed her friends which they liked to play more, FortNite or Among Us.

She found that of the 80 people who responded:

For fortnite:

0.55 of them preferred FortNite

Hence, = 0.55 × 80 people

= 44 people preferred fortnite

For Among us

30% of them preferred Among Us.

= 30% × 80 people

= 30/100 × 80 people

= 24 people preferred Among us.

How many more of her friends prefer FortNite than Among Us?

This is calculated as:

44 - 24

= 20 more people

Hence, 20 more of her friends prefer FortNite than Among Us
