1. Find the equation of the circle that has a line segment with end points (18,-13) and (4,-3) as the circle diameter. The equation takes the form (x - h)2 + (y - k)2 = 2. Where h is the x coordinate, k is the y coordinate of the center and r is the radius of the circle. h = k =​

Answers

Answer 1

Answer:

           (x - 11)² + (y + 8)² = 74

Step-by-step explanation:

The equation takes the form (x - h)² + (y - k)² = r², where  h is the x coordinate, k is the y coordinate of the center and r is the radius of the circle.

The center of circle is the middle of diameter.

The radius is the distance between the center and any point from the circumference of a circle.

The middle of diameter:

[tex]\left(\frac{18+4}2\,;\,\frac{-13-3}2\right)=\left(\frac{22}2\,;\,\frac{-16}2\right)= \left(11\,;-8\right)[/tex]   ⇒ h = 11, k = -8

The distance between the center and point (4,-3)

[tex]r=\sqrt{(11-4)^2+(-8-(-3))^2}=\sqrt{7^2+(-5)^2}=\sqrt{49+25}=\sqrt{74}[/tex]

so the equation:

(x - 11)² + (y - (-8))² = (√74)²

(x - 11)² + (y + 8)² = 74

Find the value of b, the y-intercept.
b=

Answers

Answer:

The value of the y-intercept b is 0.75

Step-by-step explanation:

Here, we want to find the value of the y-intercept

The equation of the line can be written as;

y = mx + b

where m is slope and b is the y-intercept

so y = 1/4x + c

To get the value of b , we substitute for x and y using the given point

4/5 = 1/4(0.2) + c

Multiply

0.8 = (0.25)(0.2) + b

0.8 = 0.05 + b

b = 0.8 - 0.05 = 0.75

Answer:

b=0.75

To solve first combine like terms

5y+2y-4y=3y

Then isolate your variable, do this by dividing both sides by 3.

3y=30

3y/3=30/3

Answers

Answer:

Accounts receivable in January = $68,432.60

Accounts receivable in February = $55,929.20

Accounts receivable in March = $55,958.95

Step-by-step explanation:

65% of sales collected in the month of sales + 25% in the following month + 10% in second month after sales.

In January, total accounts receivable will be the amounts outstanding or unpaid by the end of January. By the end of January, a total of 10% of December sales & 35% of January sales remain outstanding.

Accounts receivable in January = 35% of January sales + 10% of December sales

Accounts receivable in January = (35% * $124298) + (10% * $249283)

Accounts receivable in January = $43504.3 + $24928.3

Accounts receivable in January = $68432.60

In February, total accounts receivable will be the amounts outstanding or unpaid by the end of February. By the end of February, a total of 10% of January sales & 35% of February sales remain outstanding.

Accounts receivable in February = 35% of February sales + 10% of January sales

Accounts receivable in February = (35% * $124284) + (10% * $124298)

Accounts receivable in February = $43,499.4 + $12,429.8

Accounts receivable in February = $55,929.20

In March, total accounts receivable will be the amounts outstanding or unpaid by the end of march. By the end of March, a total of 10% of February sales & 35% of March sales remain outstanding.

Accounts receivable in March = 35% of March sales + 10% of February sales

Accounts receivable in March = (35% * $124373) + (10% * $124284)

Accounts receivable in March = $43530.55 + $12428.4

Accounts receivable in March = $55,958.95

Subtract −5x^2 −9x+8 from -6x^2+5

Answers

Answer:

-(x^2 - 9 x + 3)

Step-by-step explanation:

Simplify the following:

-(-5 x^2 - 9 x + 8) - 6 x^2 + 5

Factor -1 out of -5 x^2 - 9 x + 8:

--(5 x^2 + 9 x - 8) - 6 x^2 + 5

(-1)^2 = 1:

5 x^2 + 9 x - 8 - 6 x^2 + 5

Grouping like terms, 5 x^2 - 6 x^2 + 9 x - 8 + 5 = (-6 x^2 + 5 x^2) + 9 x + (5 - 8):

(-6 x^2 + 5 x^2) + 9 x + (5 - 8)

Answers

Answer:

450

2,950

thats the answer

450 is the total interest amount and 2950 is the total amount.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

To find the simple interest, we can use the formula:

A = P(1 + rt)

Now we can simply substitute the values given in the formula.

Before anything, it is a good practice to define the values of each variable.

P = 2,500

r = 9% or 0.09

t = 2

0.09×2500=225

225 is the interest for one year

450 is the total interest for two years.

Now we proceed to use the values in the formula to find total amount.

A=P(1+rt)

A = 2,500(1 + (0.09 × 2))

A = 2,500(1 + 0.18)

A = 2,500( 1.18 )

A = 2,950.00 Rupees

Hence, 450 is the total interest amount and 2950 is the total amount.

59
(6x + 5)

Answers

Answer:

Is 59 equal to (6x + 5)?

If so than your answer is: x = 9 [The value of x is 9]

Explanation:

Given 59 = (6x + 5), x is the value that makes 59 = 59.

Therefore:

59 = (6x + 5)

*given*

59 =(6x + 5)

-5 -5

*subtraction property of equality*

54 = 6x

÷6 ÷6

*division property of equality*

9 = x

x = 9

*symmetric property of equality*

_________________________

To check just substitute, simplify, and make sure 59 = 59:

x = 9 → 59 = (6x + 5) → 59 = (6(9) + 5) → 59 = (54 + 5) → 59 = 59

The cost of a pair of pants was reduced from $50 to $40. By what percent did the cost of the pair of pants decrease? 2% 10% 20% 40%

Answers

Answer:

C. 20%

Step-by-step explanation:

50*2=100

40*2=80

100-80=20

A percentage is a number or ratio that represents a fraction of 100. 

The percentage decrease in the cost of the pair of pants is 20%.

What is a percentage?

A percentage is a number or ratio that represents a fraction of 100. 

Example:

50% = 50/100 = 1/2

10% = 10/100 = 1/10

25% = 25/100 = 1/4

20% = 20/100 = 1/5

We have,

The initial cost of pair of pants = $50

The final cost of pair of pants after reduced = $40

The percentage decrease in the cost of pair of pants:

= [( Initial cost - Final cost ) / Initial cost] x 100

= [(50 - 40) / 50] x 100

= (10/50) x 100

= 20%

Thus,

The percentage decrease in the cost of the pair of pants is 20%.
