PLEASE HELP WILL MARK BRAINLIESTh=k=radius=diameter=

Answers

Answer 1

Answer:

Circle formula:

(x - h)² + (y - k)² = r²

Compare with given circle:

(x - 9)² + (y - 4)² = 36 = 6²

We see that:

h = 9, k = 4, r = 6

Diameter is twice the radius:

Diameter = 6*2 = 12

GIVING BRAINIEST!!!!!!What is the equation of the line that passes through 6,4 and 2,10

Answers

Answer:

y = -3/2x + 13

Step-by-step explanation:

(6,4) and (2,10)

Slope:

m=(y2-y1)/(x2-x1)

m=(10-4)/(2-6)

m=6/(-4)

m =  -3/2

Point-slope intercept:

y - y1 = m(x - x1)

y - 4 = -3/2(x - 6)

y - 4 = -3/2x + 9

y = -3/2x + 13

A scientist studied the replication of bacteria in a lab environment. This table gives the bacteria count for the first 12 hours. The table can be modeled using an exponential function.

Hours 2 4 6 8 10 12
Bacteria count 1,240 5,100 20,990 86,520 365,520 1,469,170

What function best represents the data?

y=300+4x
y=1240⋅2.03x
y=4x
y=300⋅2.03x

Answers

Answer: y=300⋅2.03x

Step-by-step explanation:

Answer:

D.) y = 300 ⋅ 2.03x

Step-by-step explanation:

By using the plug-in method, you use "Hours" as the X in this question.

If you plug in 2, 4, 6, 8, 10, and 12 to y = 300 ⋅ 2.03x, you will get the closest answers to "Bateria Count"

1,236.27 = 300 ⋅ 2.03^2
5,094.54= 300 ⋅ 2.03^4
2,0994.11 = 300 ⋅ 2.03^6
86,514.63 = 300 ⋅ 2.03^8
and so on- all are the closest to the chart.

Hope this helped! :)

Joe and Nancy decide to take a road trip. The first 72 miles of the drive are pretty easy, while the last 84 miles of the drive are filled with curves. They drove at an average 7 miles per hour faster for the first 72 miles of the trip. The entire trip took 3 hours. How fast were Joe and Nancy driving for the first 72 miles of the trip?

Answers

Answer:

120

Step-by-step explanation:

let r be the rate for the slower, 84 miles, portion of the trip

let t1 be the time for the 120 miles portion of the trip and t2 for the 84 miles portion

:

1) t1 + t2 = 3

2) (r+9)*t1 = 120 and r*t2 = 84

3) (r+9)*t1 + r*t2 = 120 + 84 = 204

:

expand the left side of equation 3

:

r*t1 + 9*t1 + r*t2 = 204

r*(t1+t2) +9*t1 = 204

:

substitute for (t1+t2) by using equation 1)

:

3*r + 9*t1 = 204

:

divide both sides of = by 3

:

4) r + 3*t1 = 68

:

use the equation for t1 from the equations defined at 2)

:

t1 = 120 / (r+9)

:

substitute for t1 in equation 4)

:

r + 3*(120/(r+9)) = 68

:

r^2 +9r +360 = 68 * (r+9)

:

r^2 -59r -252 = 0

:

(r-63)*(r+4) = 0

:

r = 63 and r = -4

:

we reject the negative value for r

:

John will paint the walls and ceiling of the room shown. The windows measures 3 feet by 6 feet. The door measures 7 feet by 3 feet.
Part A: Describe the surfaces John will not paint.
Part B: Judy says you need to use subtraction to find the area of the surfaces John will paint. Is Judy correct? Explain.
Part C: A gallon of paint covers about 350 squared feet. How many gallons of paint will John need to buy to paint the walls and ceiling of the room? Justify your answer.

Answers

Answer:

Step-by-step explanation:

Part A. John will not be painting the floor area of that of the door or window openings.

Part B. Subtracting the areas of the floor, door, and window from the total surface area will provide the area to be painted so Judy is correct.

Part C.

We first need to find the area to be painted.

A=floor+2(wall1)+2(wall2)-window-door

A=14(7)+2(7)8+2(14)8-3(6)-3(7)

A=98+112+224-18-21

A=395 ft^2

Since a gallon of paint will cover 350 ft^2

395ft^2(gal/350ft^2)=1.13 gal

John will need approximately 1.13 gallons of paint. (Rounded to nearest hundredth of a gallon)

A physical examination was used to screen for breast cancer in 7600 women with biopsy proven adenocarcinoma of the breast and in 11,000 age and race matched control women. The results of the physical examination were positive (i.e. a mass was palpated) in 5,500 cases and 1,700 control women (who showed no evidence of cancer at biopsy). The total population is 18,600. The sensitivity of the physical examination was:______.

Answers

Answer:

72.37%

Step-by-step explanation:

Calculation for what The sensitivity of the physical examination was

Using this formula

Sensitivity=Positive physical examination cases/Physical examination screening for breast cancer

Let plug in the formula

Sensitivity=5,500 cases / 7600 women

Sensitivity=0.7237*100

Sensitivity=72.37%

Therefore The sensitivity of the physical examination was 72.37%

Find the surface area and volume of the prism​

Answers

Answer:

I only know the first one.

The surface area of the prism is 900 cm2

Step-by-step explanation:

To solve the surface area, we need to find the area of the SURFACE not the inside of the cube. Lets do the rectangles first.

28 x 13 = 364

28 x 5 = 140

28 x 12 = 336

   1 1

   336

+  140

   364

-------------

  8 4 0

Now lets do the triangles.

Remember! To find the area of a triangle, you have to do Base x Height x 1/2 because it's half a rectangle.

(The triangles have the same area)

12 x 5 x 1/2 = 30

12 x 5 x 1/2 = 30

  30

+ 30

--------

 60

The last step is to add the areas of the triangles and the rectangles.

   1

   840

+    60

------------

   900 cm2

The answer is 900cm2

This Is not copy pasted, I actually put in all this effort.

Turner’s backyard deck cost $38.31 per square meter to build. The deck is 9 meters wide and 11 meters long. How much did it cost to build the deck?

Answers

Answer:

$3792.69

Step-by-step explanation:

First, we would find the area,

Area = width x length

Area = 9 x 11

Area = 99[tex]m^{2}[/tex]

Since each square meter costs $38.31, we would multiply the cost with the area,

Total Cost = 99 x 38.31

Total Cost = $3792.69
