The equation y = 16.50x describes the amount of money Joey earns, where x is the number of hours he works and y is the amount of money he earns.
The table shows the amount of money Kaylee earns for different numbers of hours worked.
Kaylee’s Earnings
Time (h) 2 5 8 10
Money earned ($) 39 97.50 156 195
(a) How much money does Kaylee earn per hour? Show your work.


(b) Who earns more per hour? Justify your answer.



HELP ME PLEASEEEEE

Answers

Answer:

(a) Kaylee earns $19.50 per hour.

(b) Kaylee earns more money per hour than Joey.

Step-by-step explanation:

x = # of hrs. worked

y = amount of money earned

Joey:

y = 16.50x

Kaylee:

Time (h) 2, 5, 8, 10

Money earned ($) 39, 97.50, 156, 195

y = mx + b; Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

We will be using: (2,39) and (8,156) to find the slope of this table.

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{156-39}{8-2} \\\\m=\frac{117}{6} \\\\m=19.5[/tex]

y = mx + b

y = 19.5x + b

I will be using (2, 39) to find the value of b

(2, 39)

y = 19.5x + b

39 = 19.5(2) + b

39 = 39 + b

-39  -39

0 = b

y = 19.5x + b ==> y = 17.7x + 0 =  OR  y = 19.5x (since the value of b is 0)

(a) The question wants us to find out how money Kaylee earns per hour. Recall that x = # of hrs. worked and y = amount of money earned.

y = 19.5x

She earns $19.50 per hour.

(b)

Joey: y = 16.50x (earns $16.50 per hour)

Kaylee: y = 19.5x (earns $19.50 per hour)

As you can see, Kaylee earns more money per hour than Joey.

Hope this helps!

Which symbol can be used to correctly compare the two fractionsPlease help asap!!!

Use >, <, or =.

2/5 35/100

Answers

Answer:

The symbol we can be used is " > "

Step-by-step explanation:

To compare two fractions you must make their denominator equal

Example:

To compare the fractions [tex]\frac{3}{4}[/tex] and [tex]\frac{7}{50}[/tex] ,

You should make their denominators equal. Multiply 4 by 25 to get 100 and multiply 50 by 2 to get 100, So, [tex]\frac{3*25}{4*25}=\frac{75}{100}[/tex]  and  [tex]\frac{7*2}{50*2}=\frac{14}{100}[/tex]. Since 75 > 14, then [tex]\frac{75}{100}>\frac{14}{100}[/tex] ,Which means [tex]\frac{3}{4}>\frac{7}{50}[/tex]

Let us solve the question

∵ The fractions are [tex]\frac{2}{5}[/tex] and [tex]\frac{35}{100}[/tex]

→ Change denominator 5 to 100 by multiplying it by 20

∵ [tex]\frac{2}{5} =\frac{2*20}{5*20}=\frac{40}{100}[/tex]

∵ 40 > 35

∴ [tex]\frac{40}{100}>\frac{35}{100}[/tex]

∴ [tex]\frac{2}{5}>\frac{35}{100}[/tex]

The symbol we can be used is " > "

Find the Slope for the line which passes through these two points (-1,5) and (-4,-4).

Answers

Answer: positive 3 is the final answer

Step-by-step explanation:

Answer:

9/3 or just 3

Step-by-step explanation:

First we need to recognize that points are given by numbers that represent the x and y coordinates (or locations) of the point. So in this problem, the first point (-1,5) has an x value of -1 and a y value of 5. Similarly the second point has an x value of -4, and a y value of -4.

Slope is defined as rise over run, or change in y (rise as it goes up or down)  over the change in x (or run as it moves left or right).

Change in x and y can be found by subtracting the first number from the second number.

So to calculate this, set up your equation like this:

[tex]\frac{5-(-4)}{-1-(-4)}[/tex]

After performing the subtraction, you should get:

[tex]\frac{9}{3}[/tex]

This further simplifies to 3.

Answers

Answer:

a) s = 2a sinh(b/a)

b) 18 feet

Step-by-step explanation:

The arc length is:

s = ∫ √(1 + (dy/dx)²) dx

y = a cosh(x/a)

y = ½ a (e^(x/a) + e^(-x/a))

dy/dx = ½ a (1/a e^(x/a) − 1/a e^(-x/a))

dy/dx = ½ (e^(x/a) − e^(-x/a))

(dy/dx)² = ¼ (e^(2x/a) − 2 + e^(-2x/a))

Plugging in:

s = ∫ √(1 + ¼ (e^(2x/a) − 2 + e^(-2x/a))) dx

s = ∫ ½ √(4 + e^(2x/a) − 2 + e^(-2x/a)) dx

s = ∫ ½ √(e^(2x/a) + 2 + e^(-2x/a)) dx

s = ∫ ½ √(e^(x/a) + e^(-x/a))² dx

s = ∫ ½ (e^(x/a) + e^(-x/a)) dx

s = ½ (a e^(x/a) − a e^(-x/a))

s = ½ a (e^(x/a) − e^(-x/a))

Evaluate from x=-b to x=b:

s = ½ a (e^(b/a) − e^(-b/a)) − ½ a (e^(-b/a) − e^(b/a))

s = ½ a e^(b/a) − ½ a e^(-b/a) − ½ a e^(-b/a) + ½ a e^(b/a)

s = a e^(b/a) − a e^(-b/a)

s = a (e^(b/a) − e^(-b/a))

s = 2a sinh(b/a)

We know that s = 48, and b = 20.  We also know y = 30 when x = b.

48 = 2a sinh(20/a)

24 = a sinh(20/a)

30 = a cosh(20/a)

Using the given identity:

cosh²(20/a) − sin²(20/a) = 1

a² cosh²(20/a) − a² sin²(20/a) = a²

30² − 24² = a²

a² = 324

a = 18

Therefore, the wire will be 18 feet above the ground at the lowest point.

Step-by-step explanation:

Aling Luz bought 3/8 yards of linen cloth which cost Php 72.00 per yard.She gave Php 1000.00 to the cashier.How much change will she?

Number of yards bought = 3/8

Cost of a yard = Phone 72.00

Cost of number of yards bought = Number of yards bought × Cost of a yard

= 3/8 × Php 72.00

= Php 27.00

She gave Php 1000.00 to the cashier.

The statement that logically comes next is (c) Translate triangle ABC, so that point A maps to point W

How to determine the next step

After reflecting the triangle ABC, the next step is to map point A to point W on the coordinate plane.

This is done by translating the triangle ABC i.e. by shifting or moving the triangle ABC so that points A and W would be on the same point

The table that shows a constant rate of change of -3 is Table D.

Option D is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The constant rate of change (r):

Take two ordered pairs (a, b) and (c, d)

= (d - b) / (c - a)

Now,

From Table D.

We see that,

r = (-1 - 2) / (-21 + 22) = -3/1 = -3

r = (-4 + 1) / (-20 + 21) = -3/1 = -3

r = (-7 + 4) / (-19 + 20) = -3/1 = -3

Thus,
