Find the equation of the circle in standard form.
center (5,-5)
radius = 3 units

Answers

Answer:

(x - 5)² + (y + 5)² = 9

Step-by-step explanation:

the equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k ) are the coordinates of the centre and r is the radius

here (h, k ) = (5, - 5 ) and r = 3 , then

(x - 5)² + (y - (- 5) )² = 3² , that is

(x - 5)² + (y + 5)² = 9

Hugh has $200 in his bank account. Hugh wrote six checks from his account in the following amounts: $20, $20, $12, $20, $12, and $42. He also made a deposit of $57 and was charged a $15 service fee by the bank. After all these transactions what was Hugh's balance?

Answers

The balance in Hugh's account after writing six checks, making one deposit and being charge with a service fee by the bank equals an amount of $ 116.

How to determine the balance of a bank account

Here in this question we should understand the situation like a game with the following rules for the account balance:

A check from the account means a subtraction of money.A deposit means an addition of money.Service fee means also a subtraction of money.

After a careful reading, we apply the rules described above and have the following calculation:

x = $ 200 - $ 20 - $ 20 - $ 12 - $ 20 - $ 12 - $ 42 + $ 57 - $ 15

x = $ 116

are the total costs at the
OI two truck rental
two companies equal?
Company A:
Company B:
$20 per day plus $.70 per mile
$45 per day plus S .25 per mile

Answers

Set up the equation and solve for miles:


20 + 0.70m = 45 + 0.25m

Subtract 20 from both sides

0.70m = 25 + 0.25m

Subtract 0.25m from both sides

0.45m = 25

Divide both sides by 0.45

M = 55.56 miles

A rectangle has sides measuring (6x + 4) units and (2x + 11) units.

Part A: What is the expression that represents the area of the rectangle? Show your work.

Part B: What are the degree and classification of the expression obtained in Part A?

Part C: How does Part A demonstrate the closure property for polynomials?

Answers

Answer:

Down Here ↓↓↓

Step-by-step explanation:

Hello!

A)

The area of a rectangle is L * W.

Area = (6x + 4)(2x + 11)Area = 12x² + 8x + 66x + 44Area = 12x² + 74x + 44

B)

The degree of a polynomial is the value of the highest exponent. The degree of 12x² + 74x + 44 is 2, because 2 is the highest exponent.

C)

This demonstrates the closure property, as adding, subtracting, and or multiplying polynomials will give a polynomial.

The Rhythm Record Shop orders sixty-minute cassette tapes at $1.49 and CDs at $4.98. A total of 451
items were ordered and the total amount of the invoice is $1240.86. How many of each item were
ordered?

Answers

The number of sixty-minute cassette tapes ordered is 288 and the number of CDs ordered is 163.

What are the linear equations that represent this question?

1.49a + 4.98b = $1240.86 equation 1

a + b = 451  equation 2

Where:

a = number of sixty-minute cassette tapes ordered b = number of CDs ordered

How many CDs were ordered?

Multiply equation 2 by 1,49

1.49a + 1.49b = 671.99 equation 3

Subtract equation 3 from equation 1

568.87 = 3.49b

Divide both sides of the equation by 3.49

568.87 / 3.49

Jason is considering two different jobs that he has been offered and he likes the atmosphere and

other employees equally at both companies.

With the first job he would be an apartment property manager for AMLI Company. This job is

offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he

sets a one year lease up with. The company expects Jason to work all 52 weeks of the year and 40

hours per week. He was told he could expect to set up an average of 5 lease agreements for each

week that he works.

With the second job he would work as water treatment facility manager in Gwinnett County. He

would be paid an annual salary of $46,000 a year, there are no bonuses by he gets a week off.

Both companies deduct for Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and

Federal Income Tax (14%).

AMLI's individual health insurance costs $115 per month. Gwinnett County's health insurance is

only $25 per month for an individual.

Part A: Determine how much Jason will receive in one year after all deductions have been taken

for each company. Show your work neatly.

Answers

The amount of money that Jason will receive in one year after all deductions have been taken for each company is $30,780.5 and $32562.

What is the final amount?

With the first job, he would be an apartment property manager for AMLI Company.

This job is offering Jason an hourly rate of $19. 00 an hour plus a weekly bonus of $40 for each new tenant he sets a one-year lease-up with.

The company expects Jason to work all 52 weeks of the year and 40 hours per week.

He was told he could expect to set up an average of 5 lease agreements for each week that he works.

The amount after one year will be given by an equation

Let y be the amount, x be the number of hours in a week and z be the number of the week.

y = 19x + 40z

The total number of hours in a year will be

x = 2080

Then

y = 19 × 2080 + 40 × 52

y = $ 41,600

The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be

→ 41,600 × 0.938 × 0.988 × 0.97 × 0.86

→ $ 32,160.5

The amount after the insurance will be

Amount = 32160.5 - 115 × 12

Amount = $ 30780.5

With the second job, he would work as a water treatment facility manager in Gwinnett County. He would be paid an annual salary of $46,000 a year, there are no bonuses and he gets a week off.

The amount after the deduction of Social Security (6. 2%), Medicare (1. 2%), State Income Tax (3%), and Federal Income Tax (14%) will be

→ 46,000 × 0.938 × 0.988 × 0.97 × 0.86

→ $ 35,562

The amount after the insurance will be

Let the number of the worker be 10. Then

Amount = 35,562 - 10 × 12 × 25

Amount = 35562 - 3000

Amount = $32562

What is the area of the shaded region below?

Answers

Answer:

Step-by-step explanation:

Remark

The triangle with the shaded region makes exactly 1/4 of the entire circle. So the plan is to find the area of the circle and divide by 4. That gives you the area of the triangle and the shaded region. Then you find the area of the triangle and subtract it from what you just found.

Area of the circle

Area of the circle = pi * r^2

r = 12 cm

pi = 3.14

Area of the circle = 3.14 * 12^2

Area of the circle = 3.14 * 144

Area of the circle = 452.16 cm^2

Area of 1/4 of the circle

Area of 1/4 of the circle = (1/4)*452.16

Area of 1/4 of the circle = 113.04

Area of the triangle

b = r

h = r

b = 12 cm

h = 12 cm

Area = 1/2 b * h

area = 1/2 * 12 * 12

area = 72

Area of the shaded part

Shaded part = area of 1/4 of the circle - area of triangle

Area shaded part = 113.04 - 72 = 41.04

Answer area of shaded part = 41.04
