Step-by-step explanation:

Answer: p(x) = $1*(2)^x

Step-by-step explanation:

First, the father pays him $1 for only starting the work, and for each hour, the payment is doubled.

So after the first hour, the payment wil be 2*$1 = $2.

After the second hour, the payment will be 2*(2*$1) = $1*(2)^2

After another hour, the payment will be 2*($1*(2)^2) = $1*(2)^3

We already can see the pattern here, after x hours, the payment will be:

p(x) = $1*(2)^x

This is the function that models this situation.

Answer:

y = 10x + 10

Step-by-step explanation:

(0,10) means that the y is 10 when the x is 0, which is the y-intercept

y-intercept: 10

b = y-intercept

m = slope

slope: 10

y = mx + b

y = 10x + 10

Answer:

1/18

Step-by-step explanation:

we are doing 1/2 divided into 9 parts so that would be 1/2 / 9  but when we divide fractions we turn one of the fractions upside down and instead of dividing we multiply so it would look like 1/2*1/9 = 1/18

Answer:

  4

Step-by-step explanation:

The slope formula is useful:

  m = (y2 -y1)/(x2 -x1)

  m = (13 -5)/(4 -2) = 8/2

  m = 4

The slope of the line through those points is 4.

Answer:

x=63

Step-by-step explanation:

55+62+x=180

117+x=180

180-117=63

x=63

Answer:

The answer to the question provided is 16 units.

.

Step-by-step explanation:

☆Well, we simply use the distance formula, which is:

[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }[/tex]

...

☆All we need to do is plug in!

[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{(9 - 25) {}^{2} + (12 - 12)^{2} } \\ d = \sqrt{( - 16)^{2} + (0) ^{2} } \\ d = \sqrt{256 + 0} \\ d = \sqrt{ 256 } \\ d = 16[/tex]

Answer:

Bk = 65

Step-by-step explanation:

BK as we can see is 4x + 1

If two triangles are similar, the ratio of the corresponding sides are the same

Thus;

2x+7/27 = 4x + 1/45

45(2x + 7) = 27(4x + 1)

90x + 315 = 108x + 27

108x-90x = 315-27

18x = 288

x = 288/18

x = 16

From the question;

BK = 4x + 1

BK = 4(16) + 1

BK = 64 + 1

BK = 65

Tangency is when a line is fully outside the circle and touches it in one place.

The point of tangency would be point H

Answer:

Point H is the right answer.

Step-by-step explanation:

Tangency is when the line is outside the circle and touches at single point.

Answer:

20.463

Step-by-step explanation:

3.59x5.7

5.7 pounds of coffee would cost  $20.463.

When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one method to encourage uniformity in work effort, expense, and duration. It reduces diversity and variation that is detrimental, pointless, or unnecessary.

Given, Coffee costs $3.59 per pound. Since,

1 pound of coffee costs = 3.59$

5.7 pounds of coffee costs = 3.59 * 5.7

5.7 pounds of coffee costs = 20.463

Therefore, $20.463 would be the cost of 5.7 pounds of coffee.

Answer:

3x+y-380

Step-by-step explanation:

Answer:

380+12=494

Step-by-step explanation:

Answer:

B. x = 3

C. Segment AT = 7

F. Segment AL = 22

Step-by-step explanation:

To figure out what the length of Segments AT and AL are use the equation ((2x + 1) + 15) = 7x + 1.

((2x + 1) + 15) = 7x + 1

Add 1 to 15 to get 16.

2x + 16 = 7x + 1

Subtract 7x from both sides. This cancels the +7x.

2x + 16 - 7x = 1

Combine 2x and -7x to get -5x

-5x + 16 = 1

Subtract 16 from both sides. This chancels the +16x.

-5x = 1 - 16

Subtract 16 from 1 to get -15.

-5x = -15

Divide both sides by -5. This cancels the multiplication by -5.

x = -15/-5

Dividing any two negative numbers ends in a positive. Divide -15 by -5 to get 3.

x = 3

Now, substitute x for 3 in 2x + 1 and 7x + 1 to figure out the lengths.

2(3) + 1

Mulitply 2 by 3 for 6.

6 + 1

Add 1 to 6 to get 7.

Segment AT is 7 units long.

7(3) + 1

Multiply 7 by 3 to get 21.

21 + 1

Add 1 to 21 to get 22.

Segment AL is 22 units long.
