Answer:

20 hours

Step-by-step explanation:

We can use a ratio to solve

90dollars      360 dollars

--------------- = -----------

5 hours         x hours

Using cross products

90x = 5* 360

Divide each side by 90

90x/90 = 5 * 360/90

x = 20

Answer:

Water is being collected at the rate of 11.25 gallon per minute.

Step-by-step explanation:

In this function the filling of water in the pool is dependent on the number of minutes. The more time the tap is opened the greater amount of water can be accumulated in the pool .

So time is independent and water is the dependent variable.

The function can be represented by

f(x)= xt where t is the time in minutes

90 gallons= x * 8 minutes

or x= 90/8 = 11.25 gallon per minute.

So water is being collected at the rate of 11.25 gallon per minute.

Spanish

En esta función, el llenado de agua de la piscina depende de la cantidad de minutos. Cuanto más tiempo se abre el grifo, mayor cantidad de agua se puede acumular en la piscina.

Entonces el tiempo es independiente y el agua es la variable dependiente.

La función se puede representar por

F (x) = xt donde t es el tiempo en minutos

90 galones = x * 8 minutos

o x = 90/8 = 11,25 galones por minuto.

Entonces, el agua se recolecta a una velocidad de 11.25 galones por minuto.

Let's pose x as 0, 1, 2, and 3, substituting for y to receive the "ordered pairs"

y = - 1/3(0) + 4 = 0 + 4 = 4

y = - 1/3(1) + 4 = - 1/3 + 4 = - 1/7

y = - 1/3(2) + 4 = - 2/3 + 4 = 10/3

y = - 1/3(3) + 4 = - 1 + 4 = 3

Table of ordered pairs:

x | y

0 | 4

1 | - 1/7

2 | 10/3

3 | 3

Step-by-step explanation:

Answer:  75.2 per week

Step-by-step explanation:

A 76 weeks for Ruth's laundry cost to equal the cost of the washer and dryer.

To find out how many weeks it for Ruth's laundry cost to equal the cost of the washer and dryer, to set up an equation.

Let's assume it takes "x" weeks for Ruth's laundry cost to equal the cost of the washer and dryer.

In one week, Ruth's laundry cost is $12.50. Therefore, in "x" weeks, her total laundry cost would be 12.50 × x.

The cost of the washer and dryer is $940.

Now  set up the equation:

12.50 × x = 940

To solve for "x," divide both sides of the equation by 12.50:

x = 940 / 12.50

x = 75.2

Therefore, it will take approximately 75.2 weeks for Ruth's laundry cost to equal the cost of the washer and dryer. Since the number of weeks cannot be fractional,  round up the answer to the nearest whole number.

Answer:

[tex]a_n=112\left(-\frac{1}{4}\right)^{n-1}[/tex]

Step-by-step explanation:

Geometric Sequences

There are two basic types of sequences: arithmetic and geometric. The arithmetic sequences can be recognized because each term is found as the previous term plus a fixed number called the common difference.

In the geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

We are given the sequence:

112, -28, 7, ...

It's easy to find out this is a geometric sequence because the signs of the terms are alternating. If it was an arithmetic sequence, the third term should be negative like the second term.

Let's find the common ratio by dividing each term by the previous term:

[tex]\displaystyle r=\frac{-28}{112}=-\frac{1}{4}[/tex]

Testing with the third term:

[tex]\displaystyle -28*-\frac{1}{4}=7[/tex]

Now we're sure it's a geometric sequence with r=-1/4, we use the general equation for the nth term:

[tex]a_n=a_1*r^{n-1}[/tex]

[tex]a_n=112\left(-\frac{1}{4}\right)^{n-1}[/tex]

Answer:

unit cost in dollars per mile

Step-by-step explanation:

You are given cost, miles, and time for a certain trip.

You are asked the cost for a certain number of miles, so you need a unit cost of dollars per mile.

$7.20/(12 miles) = $0.60/mile

$0.60/mile * 46 miles = $27.60

By first finding the unit cost per mile, you can then find the cost of the 46-mile trip.

Answer:

0.40, mile

Step-by-step explanation:

because you had to multiply to get the total cost and then divide the number by the total cost.

Adrienne said:

a vertical stretch by a factor of 4, a horizontal shift to the left 1 unit and a vertical shift down 3 units of the graph of the parent function f(x)=ex

f(x)=e^x

g(x)=4e^x-1+3.

by the above known facts, it can be concluded that

Adrienne is not correct

Step-by-step explanation:

i hope this helps you, i'm still doing it but i have to go for a min, one sec! <3

the correct transformations for the function g(x) = 4eˣ - 1 + 3 from the parent function f(x) = eˣ are:

- Vertical Stretch by a factor of 4.

- Horizontal Shift to the Right 1 unit.

- Vertical Shift Down 3 units.

Adrienne's statement about the transformations applied to the parent function f(x) = eˣ is not entirely correct. Let's analyze the given function g(x) = 4eˣ - 1 + 3 and determine the correct transformations.

1. Vertical Stretch by a factor of 4: This transformation is correct. Multiplying the function by 4 causes a vertical stretch, which magnifies the y-values by a factor of 4.

2. Horizontal Shift to the Left 1 unit: Adrienne incorrectly mentioned a horizontal shift to the left. In the given function, g(x), there is no explicit horizontal shift. The -1 in g(x) = 4eˣ - 1 + 3 is actually a reflection of the graph across the y-axis, causing a horizontal shift to the right by 1 unit. So, there is a horizontal shift to the right by 1 unit, not to the left.

3. Vertical Shift Down 3 units: This transformation is correct. Adding 3 to the function shifts the graph vertically downward by 3 units.

Therefore, the correct transformations for the function g(x) = 4eˣ - 1 + 3 from the parent function f(x) = eˣ are:

- Vertical Stretch by a factor of 4.

- Horizontal Shift to the Right 1 unit.

- Vertical Shift Down 3 units.

Answer:

  x = 72

Step-by-step explanation:

The sum of interior angles of a pentagon is (5-2)(180°) = 3·180°. The sum of the two right angles is 180°, so we can write the equation ...

  180° +2x° +x° +2x° = 3·180°

  5x = 2·180 = 360 . . . . divide by °, subtract 180

  x = 360/5 = 72 . . . . . . divide by 5

The value of x is 72.

Answer:

The coordinates of point Z is (-16.25, 5)

Step-by-step explanation:

The given information are;

The coordinates of the endpoint A on segment AB = (-18, 5)

The coordinates of the endpoint B on segment AB = (-4, 5)

Therefore, given that the endpoints A and B have the same y-coordinate value, (5), then segment AB is horizontal, and the length of segment AB = -4 - (-18) = -4 + 18 = 14

The point Z located at exactly 1/8 from A to B is given as follows;

[tex]Z = \left (-18 + (-4 - (-18)) \times \dfrac{1}{8} , \ 5 + (5 - 5)\times \dfrac{1}{8} \right ) = (-16.25, \ 5)[/tex]

The coordinates of point Z = (-16.25, 5).
