Answer 1

Answer:

$80 + $32x = y

Step-by-step explanation:

80 dollars is mandatory, and will always be charged no matter how many hours the electrician works. The $32 is charged based on how many hours the electrician worked. We don't know how many hours he worked, therefore we put an X next to $32 as a way to remind ourselves to multiply the amount of hours he worked times how much he charges per hour. Y would be the total fee.

Answer 2
32x+80=y

The 80 is an added fee and is NOT constant while the hourly rate goes up by 32 every hour. to get the total you add the hourly rate with the added fee.

how much do i need to make to afford a $425,000 house

Answers

The income you need to afford a $425,000 house is largely dependent on your debt-to-income ratio, credit score, and down payment. However, a general rule of thumb is to have an annual income that is at least three times the purchase price of the home, which in this case would be $1,275,000.

To more accurately determine the income needed to afford a $425,000 house, consider factors such as the interest rate on the mortgage, property taxes, homeowners insurance, and any homeowner association fees.

These additional expenses can significantly impact your monthly mortgage payment and thus your income requirements.
It's important to keep in mind that lenders have varying criteria when determining mortgage eligibility and income requirements, so it's best to speak with a mortgage professional to get a more accurate estimate based on your individual circumstances.

Step-by-step explanation:

Top box equals 10

(5x2)

Middle box equals 15

(5-2+2) x 3

Bottom box equals 10

(5x2)

Answer:

35 in sq.

Step-by-step explanation:

Find the area of each rectangle and add them together.

Area of a rectangle = length*height

Top rectangle: This one is easy. Length=2 Width=5

5*2=10

Middle rectangle: There's a missing segment in the width but we can find it. Notice the bottom rectangle's width includes the missing segment + 2 (look at the top rectangle). 5-2 is 3. Add the 2 of the known segment to the 3 of the previously unknown segment.

Length=3 Width=5

5*3=15

Bottom rectangle: This one is also easy. Length=2 Width=5

2*5=10

10+15+10=35 in sq.

a car rental company offers two plans for renting a car. plan a: 30 dollars per day and 10 cents per mile plan b: 55 dollars per day with free unlimited mileage how many miles would you need to drive in one day for plan b to save you money? enter the exact answer as an inequality using the variable m to represent the number of miles.

Answers

The required inequality to represents the cost of plan B save the money compare to plan A is given by m > 250.

Let us start by setting up an equation to represent the cost of each plan.

For Plan A, the cost (C) can be represented as,

C = 30 + 0.10m

where m is the number of miles driven.

For Plan B, the cost is a flat rate of $55 per day, regardless of the number of miles driven.

Now, for how many miles need to drive in one day for Plan B to save us money compared to Plan A.

⇒ Cost of Plan A is equal to the cost of Plan B.

⇒ 30 + 0.10m = 55

Subtracting 30 from both sides, we get,

⇒0.10m = 25

Dividing both sides by 0.10, we get

⇒m = 250

The required inequality is

m > 250.

So, drive more than 250 miles in one day, Plan B would save you money compared to Plan A.

However, if you drive exactly 250 miles, the cost for both plans would be the same.

Therefore, the exact answer as an inequality using the variable m to represent plan B save money compare to plan A is equal to m > 250.

Chris works in a tall building in downtown Columbia. We are going to view this skyscraper as a line segment.

Chris works in a tall building in downtown Columbia. We are going to view this skyscraper as a line segment.

Answers

The length of AB, which represents the distance from Chris' position to the top of the building, is approximately 34.64 stories.

To find the length of AB, we can visualize the situation as a right triangle where point A is the top of the building, point C is the front door, and point B is Chris' position.

We are given that the building is 36 stories tall, which means the vertical distance from A to C is 36 stories. Additionally, we know that Chris works at a position 10 stories above point C. Let's denote the length of AB as x.

Using the Pythagorean theorem, we can relate the lengths of the sides of the right triangle:

AC² = AB² + BC²

Since AC is the vertical height of the building and BC is the vertical distance from point C to Chris' position (which is 10 stories), we can rewrite the equation as:

36² = x² + 10²

Simplifying the equation:

1296 = x² + 100

Rearranging the equation:

x² = 1296 - 100

x² = 1196

Taking the square root of both sides to solve for x:

x = √1196

Calculating the square root of 1196, we find:

x ≈ 34.64

Therefore, the length of AB, which represents the distance from Chris' position to the top of the building, is approximately 34.64 stories.

solve t^2y'+2ty-y^3=0

Answers

The general solution to the given differential equation is

y = ± √(1 / (2ln|t| + 4/t - C2))

Solution to the differential equation

To solve the given differential equation, we can use the method of separable variables. Let's go through the steps:

Rearrange the equation to separate the variables:

t^2y' + 2ty - y^3 = 0

Divide both sides of the equation by t^2:

y' + (2y/t) - (y^3/t^2) = 0

Now, we can rewrite the equation as:

y' + (2y/t) = (y^3/t^2)

Separate the variables by moving the y-related terms to one side and the t-related terms to the other side:

(1/y^3)dy = (1/t - 2/t^2)dt

Integrate both sides of the equation:

∫(1/y^3)dy = ∫(1/t - 2/t^2)dt

To integrate the left side, let's use a substitution. Let u = y^(-2), then du = -2y^(-3)dy.

-1/2 ∫du = ∫(1/t - 2/t^2)dt

-1/2 u = ln|t| + 2/t + C1

-1/2 (y^(-2)) = ln|t| + 2/t + C1

Multiply through by -2:

y^(-2) = -2ln|t| - 4/t + C2

Now, take the reciprocal of both sides to solve for y:

y^2 = (-1) / (-2ln|t| - 4/t + C2)

y^2 = 1 / (2ln|t| + 4/t - C2)

Finally, taking the square root:

y = ± √(1 / (2ln|t| + 4/t - C2))

Therefore, the general solution to the given differential equation is:

y = ± √(1 / (2ln|t| + 4/t - C2))

A bicycle wheel with diameter 16 inches rides over a screw in the street. the screw is on level ground before it punctures the bike’s tire. after the bike has moved forward another 56π inches, how high above the ground is the screw? round to the nearest tenth of an inch.

Answers

The height of the screw = 16 inches.

How do you determine the number of revolutions in a circle?

The total distance covered in one revolution will be equal to the perimeter of the wheel. Finally, to find the total number of revolutions, divide the total distance by distance covered in one revolution.

Given that,

Diameter of a bicycle = 16 inches

The distance the bike moves (forward) after the screw punctures the tire = 56π inches

We note that the circumference of the bicycle = π·D = π × 16 = 16π inches

Therefore,

\(\frac{56\pi }{16\pi }\) = 3.5

Showing that the bicycle moves three and half complete turns (revolution) where after each complete turn, the screw starts from the bottom of the tire.

The height, h of the screw in the final half turn is given by the relation;

h = A cos(Bx - C) + D

Where

A = Amplitude of the motion = Diameter/2 = 16/2 = 8

P = The period of the motion 2π/B

Bx = The angle described by the motion = Half of one revolution = π = 180°

C = Phase shift = π

D = The mid line = Diameter/2 = 8 inches

Therefore;

h = 8×cos(π - π) + 8 = 16 inches

Hence, After the bike moves forward another 56π inches the height of the screw = 16 inches.

Answers

Answer:

the answer is 306.25 feet and b is 8 sec

Step-by-step explanation:

Explanation

The height of the ball as a function of the time is given by the following formula:

A. Maximum height of the ball

To find the value of the maximum height, we maximum the function h(t) computing its first derivative and equalling the result to zero:

Solving the last equation for t, we get time t when the height is maximum:

So the maximum height is given by the value of h(t) when t = 2.5:

The maximum height is 196ft.

B. Time until the ball hits the ground

The ball will hit the ground when h(t) = 0. So we must find the value of t such that:

Solving this equation is equivalent to finding the roots of a second-order polynomial:

Where:

• a = -16,

• c = 96.

The roots of this polynomial are given by the following formula:

when vlad moved to his new home a few years ago, there was a young oak tree in his backyard. he measured it once a year and found that it grew by 26 2626 centimeters each year. 4.5 4.54, point, 5 years after he moved into the house, the tree was 292 292292 centimeters tall. how tall was the tree when vlad moved into the house? centimeters how many years passed from the time vlad moved in until the tree was 357 357357 centimeters tall?

Answers

we can use the information given about its growth rate and the height after 4.5 years:So, it took 7 years from the time Vlad moved in until the tree was 357 centimeters tall.

Height increase per year = 26 centimeters
Years since Vlad moved in = 4.5 years
Height after 4.5 years = 292 centimeters
To calculate the initial height of the tree, we can multiply the growth rate by the number of years and add it to the starting height:
Initial height = Height after 4.5 years - (Height increase per year x Years since Vlad moved in)
Initial height = 292 - (26 x 4.5)
Initial height = 168 centimeters
Therefore, the tree was 168 centimeters tall when Vlad moved into the house.
To find out how many years passed from the time Vlad moved in until the tree was 357 centimeters tall, we can use the same formula and solve for the number of years:
Height increase per year = 26 centimeters
Initial height = 168 centimeters
Final height = 357 centimeters
To calculate the number of years, we can rearrange the formula as follows:
Years = (Final height - Initial height) / Height increase per year
Years = (357 - 168) / 26
Years = 6.04 years (rounded to two decimal places)
Therefore, it took approximately 6 years and 1 month for the tree to grow from 168 centimeters to 357 centimeters tall.
To determine the height of the oak tree when Vlad moved into the house, we can use the given information. The tree grows by 26 centimeters each year, and it was 292 centimeters tall after 4.5 years.
First, let's find the total growth during the 4.5 years:
26 cm/year * 4.5 years = 117 cm
Now, subtract the total growth from the current height to find the initial height:
292 cm - 117 cm = 175 cm
So, the oak tree was 175 centimeters tall when Vlad moved into the house.
To find out how many years passed until the tree was 357 centimeters tall, we can use the growth rate again:
First, find the difference in height between the target height (357 cm) and the initial height (175 cm):
357 cm - 175 cm = 182 cm
Now, divide the difference in height by the growth rate to find the number of years:
182 cm / 26 cm/year = 7 years
