Can someone please help me with this question thank you

Like $45.95 I think I’m sorry if you get it. Wrong

The question is based on exponential growth, the worker will be earning an hourly wage of $10.00 after approximately 5.9 years of receiving a 4% annual raise.

The subject of this problem is exponential growth, which is based on the formula y = a(1 + r)^t, where a is the initial amount, r is the rate of growth (expressed as a decimal), and t is the time period. In this case, your initial wage (a) is $7.95 per hour and the rate of growth (r) is 4% or 0.04. The future wage (y) is $10.00 per hour. So, the equation becomes:
10 = 7.95 * (1.04 ^t).
To solve for 't', you first divide both sides by 7.95 to isolate (1.04 ^t) on one side, resulting in 1.26 = (1.04 ^t).
You then take the natural logarithm (log base e, also represented as 'ln') of both sides of the equation to eliminate the exponential, resulting in ln(1.26) = t * ln(1.04).
Finally, you divide both sides by ln(1.04) to solve for 't', resulting in an approximate value of 't' as 5.9 years.
Therefore, the worker will be earning $10.00 per hour approximately after 5.9 years.

A. Traffic on the side with the broken yellow line. The dashes signify the “openness” of the ability that the drivers on that side have to pass.

Answer:

A). Traffic on the side with broken yellow line

Step-by-step explanation:

A solid yellow line used in two lane roadways where passing or crossing is strictly prohibited. It is dangerous and may lead to serious accidents while violating this.

                             On the other hand, broken yellow line on the roadways indicates that vehicles moving can pass or cross the road when only it is safe to cross the lane.

Therefore, when the center line is one solid yellow line and one broken yellow line, then the vehicles on the side of the broken lines may cross the line to pass only when it is safe to cross.

Answer: The line that passes through the points  (0,1) and  (-7,0). Observe the graph attached.

Step-by-step explanation:

By definition, a line intersects the y-axis when the value of "x" is zero ([tex]x=0[/tex]), then if the y-intercept  is 1, then the point where the line intersects the y-axis is:

(0,1)

By definition, a line intersects the x-axis when the value of "y" is zero ([tex]y=0[/tex]), then if the x-intercept  is -7, then the point where the line intersects the x-axis is:

(-7,0)

Therefore, now you know this, you can graph a line that passes through the points  (0,1) and  (-7,0). Observe the graph attached.

Answer:

Check the attached graph

Step-by-step explanation:

Given that y-intercept is 1.

That means graph passes through the point (0,1).

Given that x-intercept is -7.

That means graph passes through the point (-7,0).

Now we need to graph the line using above information. So begin by graphing both points .

Now draw a line joining both points to get the final graph.

Answer:

The reflection is across the x-axis

Step-by-step explanation:

* Lets revise the reflection

- If point (x , y) reflected across the x-axis

∴ Its image is (x , -y)

- If point (x , y) reflected across the y-axis

∴ Its image is (-x , y)

- If point (x , y) reflected across the line y = x

∴ Its image is (y , x)

- If point (x , y) reflected across the line y = -x

∴ Its image is (-y , -x)

* Now lets solve the problem

∵ The endpoints of a line segment are (3 , 2) and (2 , -3)

∵ The image of the endpoints after the reflection are (3 , -2) and (2 , 3)

* Lets study the change

# The x-coordinates of the points are 3 and 2

# The x-coordinates of the images are 3 and 2

# The y-coordinates of the points are 2 and -3

# The y-coordinates of the images are -2 and 3

- The change is in the signs of the y-coordinates

∴ The reflection is across the x-axis

Answer:

Option A is correct that is Surface Area of the Cylinder is 1659 in.²

Step-by-step explanation:

Given:

Radius of the Cylinder , r = 11 in.

Height of the Cylinder , h = 13 in.

We have to find the Surface Area of Cylinder to the nearest Whole number.

We know that,

Surface Area of the Cylinder = 2πr(r+h)

                                                 = 2 × 22/7 × 11 ( 11 + 13 )

                                                 = 2 × 22/7 × 11 × 24

                                                 = 1659.42 in.²

                                                 = 1659 in.²  (nearest whole number)

Therefore, Option A is correct that is Surface Area of the Cylinder is 1659 in.²

Answer:

Leah has 48 marbles.

Step-by-step explanation:

Represent the number of marbles that each person has by L and D.

Leah has 28 more marbles than Dan:  L = D + 28.

Then (1/3)L = (4/5)D.  Here the LCD is 15, and so multiplying this equation by 15 will remove the fractions:  15(1/3)L = 15(4/5)D.  

Therefore, 5L = 12D, and D = 5L/12.

Then, since L = D + 28,        L = (5/12)L + 28, or

12L = 5L + 336, or

7L = 336, or

L = 336/7 = 48.

Leah has 48 marbles.  That means that Dan has 20 marbles.

The number of marbles Leah has is 48 and Dan is 20 if Leah has 28 more marbles than Dan. 1/3 of Leah’s marbles is equal to 4/5 of Dan’s marbles.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Leah has 28 more marbles than Dan. 1/3 of Leah’s marbles is equal to 4/5 of Dan’s marbles.

Let x be the number of marbles Leah has.

Let y be the number of marbles Dan has.

Leah has 28 more marbles than Dan:  

x = y + 28

(1/3)x = (4/5)y

Solving above two linear equation, we get:

5x = 12y

5(y + 28) = 12y

5y + 140 = 12y

12y - 5y = 140

7y = 140

y = 140/7 = 20

x = 20 + 28 = 48

Thus, the number of marbles Leah has is 48 and Dan is 20 if Leah has 28 more marbles than Dan. 1/3 of Leah’s marbles is equal to 4/5 of Dan’s marbles.

Solve the equation by replacing x with -7 and then -1.

Then subtract the two to find the difference and divide that by the difference between -7 and -1.

f(-7) = -7^2 + 2(-7) -8 = 49 -14 -8 = 27

f(-1) = -1^2 + 2(-1) -8 = 1 -2 - 8 = -9

Difference between 27 and -9 = -36

Difference between -1 and -7 = -6

Answer:

The equation of the hyperbola is x²/16 - y²/9 = 1

Step-by-step explanation:

* Lets study the equation of the hyperbola

- The standard form of the equation of a hyperbola with  

  center (0 , 0) and transverse axis parallel to the x-axis is

  x²/a² - y²/b² = 1

- The length of the transverse axis is 2a

- The coordinates of the vertices are (±a , 0)

- The length of the conjugate axis is 2b

- The coordinates of the co-vertices are (0 , ±b)

- The coordinates of the foci are (± c , 0),  

- The distance between the foci is 2c where c² = a² + b²

- The distance between the vertex and the focus in-front of it is c - a

* Now lets solve the problem

- The distance from a vertex to the center of the mirror

∵ The vertex of the mirror is (a , 0)

∵ The distance between a vertex and the center of the mirror

  is 4 inches

∴ a = 4

∵ The distance between the vertex and a focus in front of  the surface

  of the mirror is 1

∵ The distance between the vertex and the focus in-front of it is c - a

∴ c - a = 1

∴ c - 4 = 1 ⇒ add 4 to the both sides

∴ c = 5

- The mirror has a horizontal transverse axis and the hyperbola is

 centered at (0, 0)

∴ The equation of the hyperbola is x²/a² - y²/b² = 1

- Lets find b from a and c

∵ c² = a² + b²

∵ c = 5 and a = 4

∴ (5)² = (4)² + b²

∴ 25 = 16 + b² ⇒ subtract 16 from both sides

∴ 9 = b² ⇒ take √ for both sides

∴ b = ±3

- Lets write the equation

∴ x²/(4)² - y²/(3)² = 1

∴ x²/16 - y²/9 = 1

* The equation of the hyperbola is x²/16 - y²/9 = 1

The distance of the focus from the center is the sum of the distance from

the focus to the surface and the vertex distance.

Correct response:

Given:

Distance of the vertex from the center = 4 inches

Distance of the focus from the mirror surface = 1 inches

Coordinates of the center of the mirror = (0, 0)

Required:

To write the equation of the hyperbola that can be used to model the mirror

Solution:

The equation of an hyperbola having an horizontal transverse axis is presented as follows;

Where;

(h, k) = The coordinate of the center

a = Center to vertex distance

b² = c² - a²

Where;

c = The from the center to the vertex

Therefore;

a = 4

(h, k) = (0. 0)

c = 4 + 1 = 5

b² = 5² - 4² = 9

b = √9 = 3

The equation of the hyperbola is therefore;

To factor the expression 3x^4 - 3x^3 - 18x^2 completely, factor out the GCF 3x^2, then factor the quadratic expression inside the parentheses (x^2 - x - 6) into (x - 3)(x + 2).

To factor the expression 3x^4 - 3x^3 - 18x^2 completely, we can first factor out the greatest common factor (GCF), which in this case is 3x^2. This gives us 3x^2(x^2 - x - 6). To factor the quadratic expression inside the parentheses, we can use the quadratic formula or factor by grouping. The quadratic expression x^2 - x - 6 can be factored as (x - 3)(x + 2).

Therefore, the completely factored expression is 3x^2(x - 3)(x + 2).

Answer: The height of the container is 10 centimeters. If its diameter and height were both doubled, the container's capacity would be 8 times its original capacity.

Step-by-step explanation:

The volume of a cone can be calculated with this formula:

[tex]V=\frac{\pi r^2h}{3}[/tex]

Where "r" is the radius and "h" is the height.

We know that the radius is half the diameter. Then:

[tex]r=\frac{12cm}{2}=6cm[/tex]

We know the volume and the radius of the conical container, then we can find "h":

[tex]120\pi cm^3=\frac{\pi (6cm)^2h}{3}\\\\(3)(120\pi cm^3)=\pi (6cm)^2h\\\\h=\frac{3(120\pi cm^3)}{\pi (6cm)^2}\\\\h=10cm[/tex]

The diameter and height doubled are:

[tex]d=12cm*2=24cm\\h=10cm*2=20cm[/tex]

Now the radius is:

[tex]r=\frac{24cm}{2}=12cm[/tex]

And the container capacity is

[tex]V=\frac{\pi (12cm)^2(20cm)}{3}=960\pi cm^3[/tex]

Then, to compare the capacities, we can divide this new capacity by the original:

 [tex]\frac{960\pi cm^3}{120\pi cm^3}=8[/tex]

Therefore,  the container's capacity would be 8 times its original capacity.

Answer:

1510 vehicles

Step-by-step explanation:

First you need to determine how many feet cars and trucks occupy.

In 5 miles:

Cars fill up 80%     = 0.80 x 5 miles = 4 miles

Trucks fill up 20%  = 0.20 x 5 miles = 1 mile

Because we know the lengths and distances of the cars and trucks in feet, let's convert the miles they cover into feet.

Cars = 4 miles x 5280 ft/mile = 21,120 ft

Trucks = 1 mile x 5280 ft/mile =  5280 ft

So how many cars would there be if they covered at least 21,120 ft?

Considering that there is 3 ft between each car and a car has a length of 13.5 ft, a single car will cover 16.5 ft.

To see how many cars then fit in 21,120 ft, just divide it by the distance one car covers.

[tex]\dfrac{21,120ft}{16.5 ft/car} = 1,280 cars[/tex]

So how many trucks would there be if they covered at least 5,280 ft?

A truck is 20 ft long and again there is a space of 3 ft in between. So we add that up to see how many feet a single truck needs.

20 ft + 3 ft = 23 ft

We then take that total and divide the feet covered by trucks.

[tex]\dfrac{5,280ft}{23ft/truck}= 229.57 trucks[/tex]

Since we cannot have half a truck, we round that off to the nearest whole number which will be 230 trucks.

So we add the number of trucks and cars to get the number of vehicles in total:

1280 + 230 = 1,510 vehicles

Part 1) The system of equations is equal to

12x+y=66.75

3x+10y=82.50

Part 2) The cost of one drink is $5

Step-by-step explanation:

Part 1) Write a system of equations that can be used to find the price of one drink and the price of one bag of popcorn

Let

x----> the price of one drink

y ----> the price of one bag of popcorn

we know that

Jason

12x+y=66.75 -----> equation A

Henry

3x+10y=82.50 -----> equation B

Part 2) Using these equations, determine and state the price of a drink, to the nearest cent

12x+y=66.75 -----> equation A

3x+10y=82.50 -----> equation B

Solve the system of equations by elimination

Multiply the equation A by -10 both sides

-10*(12x+y)=66.75*(-10)

-120x-10y=-667.5 -----> equation C

Adds equation B and C and solve for x

3x+10y=82.50

-120x-10y=-667.5

-----------------------------

3x-120x=82.50-667.5

120x-3x=667.50-82.50

117x=585

x=5

therefore

The cost of one drink is $5
