Congratulations! You just landed your dream job. You have three choices for your salary. Which of the following options would result in the greatest payday at the end of your first month of employment?

a. You can receive a lump sum of $1,500,000.



b. You can receive $50,000 initially and $100,000 per day for the next 30 days.



c. You can receive $.02 on the first day and double the amount received each day for the next 30 days.

Answers

Answer:

(b)

Step-by-step explanation:

a=1,500,000

b=3,050,000

Receiving $50,000 initially and $100,000 per day for the next 30 days, would result in the greatest payday at the end of the first month of employment, with a total amount of $3,050,000

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

To determine which option would result in the greatest payday at the end of the first month of employment, let's calculate the total amount for each option:

a)

Lump sum of $1,500,000

The total amount is $1,500,000.

b)

$50,000 initially and $100,000 perday for the next 30 days

The total amount is $50,000 (initial) + $100,000/day * 30 days

T = $50,000 + $3,000,000

On simplifying the equation , we get

T = $3,050,000

Hence , receiving $50,000 initially and $100,000 per day for the next 30 days would result in greater payday

Answer:

Step-by-step explanation:

Review the attached graph

By using geometry to evaluate the given integral, the value is equal to 6 units.

How to use geometry to evaluate an integral?

In order to use a geometry to evaluate a definite integral, you should identify the portion of a graph which corresponds to the given integral.

Also, you'll mark out the geometric shapes that are formed on the graph, so as to enable you calculate their areas. Finally, you'll add the areas together.

From the graph of the integral shown in the image attached below, the geometric shapes that are formed are rectangle and triangles.

For the area of rectangle, we have:

Area of rectangle = L × B

Area of rectangle = 2 × 2

Area of rectangle = 4 units.

For the area of triangle, we have:

Area of triangle = 1/2 × b × h

Area of triangle = 1/2 × 2 × 2

Area of triangle = 2 units.

Total area = 4 + 2

Total area = 6 units.

Sometimes the relationships involving secants, tangents, and chords can be difficult to remember. There is basically one rule that applies to all of these geometries:

  the product of segment lengths to the circle from the point of intersection of the secants/tangents/chords is the same

A tangent can be thought of as a secant that has a length of 0 between its end points. That is, the two lengths from the point of intersection to the circle are the same.

Arthur has decided to start saving for a new computer. His money is currently in a piggy bank at home, modeled by the function s(x) = 85. He was told that he could do the laundry for the house and his allowance would be a(x) = 10(x − 1), where x is measured in weeks. Explain to Arthur how he can create a function that combines the two and describe any simplification that can be done.

Answers

Answer:

Two or more independent functions (say f(x) and g(x)) can be combined to generate a new function (say g(x)) using any of the following approach.

h(x) = f(x) + g(x)h(x)=f(x)+g(x) h(x) = f(x) - g(x)h(x)=f(x)−g(x)

h(x) = \frac{f(x)}{g(x)}h(x)=

g(x)

f(x)

h(x) = f(g(x))h(x)=f(g(x))

And many more.

The approach or formula to use depends on the question.

In this case, the combined function is:

f(x) = 75+ 10xf(x)=75+10x

The savings function is given as

s(x) = 85s(x)=85

The allowance function is given as:

a(x) = 10(x - 1)a(x)=10(x−1)

The new function that combined his savings and his allowances is calculated as:

f(x) = s(x) + a(x)f(x)=s(x)+a(x)

Substitute values for s(x) and a(x)

f(x) = 85 + 10(x - 1)f(x)=85+10(x−1)

Open bracket

f(x) = 85 + 10x - 10f(x)=85+10x−10

Collect like terms

mark as brainiest

f(x) = 85 - 10+ 10xf(x)=85−10+10x

f(x) = 75+ 10xf(x)=75+10x

A revenue department is under orders to reduce the time small business owners spend filling out pension form ABC-5500. Previously the average time spent on the form was 5.2 hours. In order to test whether the time to fill out the form has been reduced, a sample of 60 small business owners who annually complete the form was randomly chosen, and their completion times recorded. The mean completion time for ABC-5500 form was 4.5 hours with a standard deviation of 1.6 hours.

Required:
In order to test that the time to complete the form has been reduced, state the appropriate null and alternative hypotheses.

Answers

Considering the situation described, we have that:

The appropriate null hypotheses is [tex]H_0: \mu = 5.2[/tex].The appropriate alternative hypotheses is [tex]H_1: \mu < 5.2[/tex].

What are the hypotheses tested?

At the null hypotheses, it is tested if the mean has not been reduced, that is, it still is of 5.2 hours, hence:

[tex]H_0: \mu = 5.2[/tex].

At the alternative hypothesis, it is tested if the mean has been reduced, that is, it is now of less than 5.2 hours, hence:

Is the equation of the new parabola 0.1? Please let me know because I’m confused.

Answers

Answer:

y=[tex]\frac{1}{10} x^2[/tex]

Step-by-step explanation:

You're partially correct.

Let me explain:

When a parabola is scaled vertically, think of it this way: a parabola is being stretched up or smooshed downwards, by some math god who can defy all forms of life and dimensions.

When a parabola, in y=a[tex]x^{2}[/tex], is shifted vertically, when a>1, it appears 'skinnier'. The parabola went on a diet! However, when 0<a<1, the parabola seems wider and fat.

Knowing this knowledge, when factored vertically by a factor of x, it means that it is the coefficient of the parent graph  y=a[tex]x^{2}[/tex], which means 1/10 goes before [tex]x^{2}[/tex].

Summing all of this up, your answer would have the equation of the new parabola as y=[tex]\frac{1}{10} x^2[/tex]

Scaled vertically means not reflected over x axis .

y=x^2

Here

a=1

Now it's vertically scaled

so

|a|=1/10=0.1

New equation

y=0.1x^2

You are renting a beach house for the summer. The cost of renting the beach house plus the one-time security deposit is represented by the equation y = 151x + 575 , where represents the number of days that the beach house is rented and y is the total cost of the rental. What is the cost of the security deposit ?

Will mark the brainliest!

Please someone explain this to me. Needs to be tonight!

Answers

Answer:

The one-time security deposit is just 575, if you add it to the cost of renting the beach house, you then get y, which is the total cost of everything. haha, its logical.

so,

The one-time security deposit is just 575.

and

The cost of renting the beach house is 151x.

while

The total cost of the rental is y, i.e 151x + 575.

Answer:

575

Step-by-step explanation:

The answer is included in the question already

The cost of renting = security deposit + rental per day

y - is total cost of rentingOne off security deposit = 575Rental cost = 151 per day

So the answer is 575

Here is the question

Answers

Answer:

Step-by-step explanation:

The curve is maybe a bit easier to visualize if you write it as x = 4sin(y). The area is

∫[0,π/2] (4-x) dy

= ∫[0,π/2] (4-4sin(y)) dy = 2π-4

∫4-4sin(y) dy = 4y + 4cos(y)

This is a bit easier than using vertical strips, where the area is

∫[0,4] arcsin(x/4) dx

since integrating arcsin(x/4) involves integration by parts.

u = arcsin(x/4)

du = 1/√(16-x^2) dx

dv = dx

v = x

∫arcsin(x/4) dx

= x arcsin(x/4) - ∫x/√(16-x^2) dx

= x arcsin(x/4) + √(16-x^2)
