What is the equation of a circle with a center located at (4, -1) and a radius of 9?

Answers

Answer 1

Answer:

(x-4)^2 + (y+1)^2 = 81

Step-by-step explanation:

you clearly have internet access and could have very quickly searched for the equation of a circle.

(x-h)^2 + (y-k)^2 = r^2

with (h,k) being the center.

=> (x-4)^2 + (y+1)^2 = 81

Part A
This year, water usage has increased by 20% for both regular days and special events.
LAST YEAR'S WATER USAGE:
All regular days - 13,505 gallons
Per special event - 18.5 gallons
Total for the year - 13,616 gallons
Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted.

Answers

Answer:

The total water usage at the park this year, in gallons, U = 16,206 + 22.2·x

Step-by-step explanation:

The given parameters are;

The increase in water usage for both regular days and special event for the current year = 20%

The water usage for last year regular days = 13,505 gallons

The water usage per special event = 18.5 gallons

The total water usage = 13,616 gallons

Therefore, we have;

The water usage for regular days on the current year = 13,505 gallons + (20/100)×13,505 gallons = 16,206 gallons

The water usage per special event for the current year, x = 18.5 gallons + (20/100) × 18.5 gallons = 22.2 gallons

The total water usage, U, at the park this year in terms of 'x', the number of special events the park hosted is given by the sum of the amount of water used on regular days and the product of 'x', and the amount of water used per special event this year as follows;

U = 16,206 gallons + x × 22.2 gallons

∴ The total water usage at the park this year, U = 16,206 + 22.2·x

Answer:

U=16,206+22.2 ^. x

Professor Rosencrantz flips a fair coin once. Professor Guildenstern flips a fair coin three times. What is the probability that Professor Rosencrantz obtains more heads than Professor Guildenstern

Answers

Answer:

9/13 = 0.6923

Step-by-step explanation:

We start by defining

A as event that head was flipped

B1 = event that coin is biased

B2 = event that it is unbiased

P(B1) = 3/5

P(B2) = 2/5

P(A|B1) = 3/4

P(A|B2) = 2/4 = 1/2

When we solve this using bayes theorem we have to find

p(B1|A) = [P(B1) x P(A|B1)]/[P(B1) x P(A|B1) + P(B2) x P(A|B2)

= 0.6 x 0.75 / 0.6 x 0.75 + 0.4x0.5

= 0.45/0.45+0.2

= 0.45/0.65

= 0.6923

Answers

Answer:

Step-by-step explanation:

Find area of square and subtract out area of semi-circle; the diameter of the semi-circle equals the side of the square, which is 4 so radius is 2

A(square) = 4 x 4 = 16

A(semi-circle) = πr²/2

Answer:

Hello! answer: B.

attention: im using 3.14 for pi so answers may vary. ok so in this picture we are provided with the diameter to find area we can do radius × radius × 3.14

16 ÷ 2 = 8 8 × 8 = 64

64 × 3.14 = 200.96 When you round this up it's 201 so approximately the answer would be B. Hope that helps!

Calculate the marked price (original price) if

a. After 25% discount, the price of an article is Rs 7500,


please with explanation and calculation the answer should be Rs 10 000

Answers

To get the original price we are going to;

1) Subtract the discount percentage from 100 to get the original price percentage.

100 - 25 = 75 %

2) Now we are going to multiply the discounted price by 100.

7500 x 100 = 750,000

3) Now we are going to divide the discounted price by the original price percentage.

750,000 / 75 = 10,000

Therefore the original price is Rs 10,000

A right circular cone has a radius of 6 inches and a slant length of 10 inches. A right cylinder has a radius of 8 inches and a height of 12 inches. How many cones full of water are needed to fill the cylinder

Answers

Answer:

6.4  cones full of water

Step-by-step explanation:

Given data

Radius of cone= 6inches

Slant height= 10 inches

Volume of cone= 1/3πr^2h

V= 1/3*3.142*6^2*10

V=  1/3*3.142*36*10

V=  1/3*1131.12

V= 377.04 cubic inches

Radius of right cylinder= 8 inches

Height= 12 inches

Volume of cylinder= πr^2h

Volume= 3.142*8^2*12

Volume= 3.142*64*12

Volume=2413.056 cubic inches

Hence the number of cone full of water needed to fill the cylinder is

=Volume of cylinder/volume of cone

=2413.056/377.04

=6.4  cones full of water

Answers

Step-by-step explanation:

5x + 17 = 4(3x - 1)

Distribute

5x+17 = 12x -4

Subtract 5x from each side

5x+17-5x = 12x-4-5x

17 = 7x-4

Add 4 to each side

17+4 = 7x-4+4

21 = 7x

Divide by 7

21/7 = 7x/7

3 =x

Answer:

x = 3

Step-by-step explanation:

5x + 17 = 4(3x - 1)

Distribute on the right side.

5x + 17 = 12x - 4

Subtract 12x from both sides. Subtract 17 from both sides.

-7x = -21

Divide both sides by -7.

x = 3

Pranav paints a wall of area 53m^2 one litre of paint covers an area of 4.5m^2 paint is sold in 2.5 litre tins, each costing $24.75 Pranav buys the least number of tins to paint this wall work out the cost of the paint

Answers

Answer:

The cost of the paint will be $123.75.

Step-by-step explanation:

Since Pranav paints a wall of area 53m ^ 2, and one liter of paint covers an area of 4.5m ^ 2, and paint is sold in 2.5 liter tins, each costing $ 24.75, if Pranav buys the least number of tins to paint this wall, to determine the cost of the paint, the following calculation must be performed:

(53 / 4.5) = liters of paint needed

11.77 = liters of paint needed

11.77 / 2.5 = tins of paint needed

4.71 = tins of paint needed (rounds to 5)

5 x 24.75 = Total cost

123.75 = Total cost

The cost of the paint will be $123.75.
