Find the rate of change

Answers

Answer:

The rate of change of function is: 2

Step-by-step explanation:

Using the given table we have to exclude two pairs of input and output.

The rate of change or slope of function is given as:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

We take first two pairs of input/output from the table

(x1,y1) = (1,11)

(x2,y2) = (2,13)

Putting the values

[tex]m = \frac{13-11}{2-1}\\m =\frac{2}{1}\\m = 2[/tex]

Hence,

notation?

A. 7.2x10.5

B. 7.2 x 106

C.7.2 x 105

D.7.2 x 10

Type Your

Answers

Answer:

7.2 *10⁻⁵

Step-by-step explanation:

Given the diameter of the hair expressed as 0.000072, we are to express it in scientific notation.

The standard form of scientific notation is expressed as;

A * 10ⁿ

A is a value from 1 to 9

n is any integer.

Rewriting 0.000072 in this form, we will need to shift the decimal point to the front 5 times to have;

0.000072 = 7.2 *10⁻⁵ where;

A = 7.2 and n = -5

Note that the power is a negative value since the value is less than 1.

The highest number here is 2.01, so we start by looking for an answer that begins with 2.01. Then we compare 1.48, 1.237,1.234, and 1.2. Look into the tenths place to find that 1.48 has a larger tenths place than any other number. continue this cycle to have the full correct order.

(Car repair) The bill including parts and labor for the repair of your car is shown. From what is given, can you determine how many hours were spent on labor ? Explain.

Answers

Answer:

2.25 hours or 2 hours and 15 minutes

Step-by-step explanation:

Using the information from the bill shown in the question we can determine the number of hours spent by first subtracting the amount of money spent on parts from the overall total, which would leave us with the total amount spent on labor. Now we would simply divide this by $44 which is how much each hour of labor costs. Finally, this would leave us with the total number of hours of labor that the mechanic put into the car repair.

$384 - $285 = $99

$99 / 44 = 2.25 hours or 2 hours and 15 minutes  (0.25 * 60 minutes)

If you look at the lines both angle 8 and 4 are on the bottom right side of the intersection, therefore they are corresponding angles.

Ty ate 5 and Rob ate 15 which is 3 times more than Ty. A total of 20 pieces have been eaten from the 36 you started with. Eaten = 16.

4.Given AABC, with AB = 5cm, BC = 7cm and AC = 8cm, what is the area of the triangle?

Answers

In Triangle ABC
We have AB=5 cm
BC=7 cm
AC=8 cm

Use Heron's formula with
sides a,b and c
Perimeter,s=(a+b+c)/2
Area= √s(s−a)(s−b)(s−c)

S=(AB+BC+AC)/2
=(5+7+8)/2
=20/2
=10cm

Area of ABC= √10(10-5)(10-7)(10-8)
= √10(5)(3)(2)
= √300
=17.3205 cm

Write 32 +24 as a product of two factors using the gcf and the distributive property

Answers

Answer:

4 * 14

Step-by-step explanation:

Given

32 + 24

Required

Write as a product of two factors

First, we need to get the GCF of 32 and 24

The factors of 32 and 24 are:

[tex]32 = 1, 2, 4, 8, 16, 32.[/tex]

[tex]24 = 1, 2, 3, 4, 6, 8, 12, 24[/tex]

The GCF (greatest common factor) is 8

So, the expression 32 + 24 can be rewritten as:

[tex]32 + 24= 4(8 + 6)[/tex]

Add 8 + 6

[tex]32 + 24= 4(14)[/tex]

[tex]32 + 24= 4 * 14[/tex]

Hence,

32 + 24 can be rewritten as 4 * 14

3. Repeat this process to find the width and height of a newer 48-inch television whose

screen has an aspect ratio of 16:9.

Do not include units in your answer - write only the Mumber rounded to the nearest tenth

What is the height?

Answers

Answer:

23.5"

Step-by-step explanation:

Please see attached a sketch of the television

the size of a television is described by the length of its diagonal in inches.

in this case, the diagonal of the television is 48"

we are told that the aspect ratio is 16:9

hence the dimension of the television as seen from the draft is

length= 16x

height=9x

Applying Pythagoras theorem

(16x)^2+(9x)^2= 48^2

256x^2+81x^2=2304

337x^2=2304

divide both sides by 337 we have

x^2=2304/337

x^2=6.8367

x=√6.8367

x=2.6

What is the height

H=9x

=9(2.6)

=23.5"

What is the equivalent amount in year ten of an expenditure of $5,000 in year one, $6,000 in year two, and amounts increasing by $1,000 per year through year ten?

Answers

Answer:

The correct answer is the equivalent amount is $139,059.41

Step-by-step explanation:

According to the scenario, the computation of the equivalent amount in year ten is shown below;

= $5,000 × (P/A, 10%,10) + $1,000 × (P/G, 10%,10)

= $5,000 × 6.1466 + $1,000 × 22.8913

= $30,723 + $22,891.30

= $53,614.30

Now the equivalent amount is

= $53,614.30 × (F/P, 10%,10)

= $53,614.30 × 2.5937

= $139,059.41

Hence, the equivalent amount is $139,059.41

A group of four friends attend a movie. The expression below represents the total

amount of dollars spent by the group after purchasing four tickets, P small bags of

popcorn, and D drinks,

32 + 5P + 3D

Answers

Question Requirement:

Simplify expression that represents the total cost of tickets and snacks or beverages

Answer:

The total cost of tickets, snacks and beverages =

$54

Step-by-step explanation:

The first thing here is to ascertain the prices of each item (ticket, a bag of popcorn, and drinks).  We assume that the price of the ticket is $8 (32/4) since there are four tickets for four friends, and  $8 x 4 = $32.  Now, we also assume that a small bag of popcorn costs $2 while drinks cost $4 each.

From the equation, we can ascertain that 5 bags of popcorn were bought while 3 bottles of drinks were purchased.

Since the total cost spent is represented by the expression,

32 + 5P + 3D

Therefore, the total cost spent by the four friends

= 32 + (5 * 2) + (3 * 4)

simplifying the above expression

= 32 + 10 + 12

= $54

Write equations (both, Point Slope & Slope Intercept Forms) of the line with
slope of -2 and point (9,2).

Answers

Answer:

Equation of line in Point Slope Form is [tex]\mathbf{y-2=-2(x-9)}[/tex]

Equation of line in Slope Intercept Form is: [tex]\mathbf{y=-2x+20}[/tex]

Step-by-step explanation:

We need to write equation of line having slope -2 and point (9,2)

a) Equation in Point Slope Form

The general equation of point slope form is: [tex]y-y_1=m(x-x_1)[/tex]

Where x₁ and y₁ are the points of line and m is slope.

x₁=9 and y₁=2 and m=-2

Putting values in formula and finding equation:

[tex]y-y_1=m(x-x_1)\\y-2=-2(x-9)[/tex]

So, Equation of line in Point Slope Form is [tex]\mathbf{y-2=-2(x-9)}[/tex]

b) Equation in Slope Intercept Form

The general equation of Slope Intercept Form is: [tex]y=mx+b[/tex]

where m is slope and b is y-intercept

Finding y-intercept using slope m=-2 and point(9,2)

[tex]y=mx+b\\2=-2(9)+b\\2=-18+b\\b=2+18\\b=20[/tex]

The equation in slope m=-2 and b=20 is:

[tex]y=mx+b\\y=-2x+20[/tex]

So, equation of line in Slope Intercept Form is: [tex]\mathbf{y=-2x+20}[/tex]
