Answer:

  y = 2/3x + 5/3

Step-by-step explanation:

The slope of the line is ...

  slope = (change in y)/(change in x) = (3-1)/(2-(-1)) = 2/3

Then the point-slope form of the desired line can be written ...

  y = m(x -h) +k . . . . . slope m through point (h, k)

  y = 2/3(x +1) +1 . . . . slope 2/3 through point (-1, 1)

  y = 2/3x + 5/3 . . . . . . simplify to slope-intercept form

The figure shown is made up of a cone and a cylinder. The height of the cone is 5 ft and its diameter is 12 ft. The height of th
elena-s [515]

The lateral area of a cone is 147ft².

The total surface area of the cylinder is 867ft².

The total surface area is 1014ft²

<h3>What is the lateral surface area of a cone?</h3>

The lateral area of a cone is defined as the area covered by the curved surface of the cone.

Lateral area of a cone = πr x √(r² + h²)

Where:

  • r = radius = 12/2 = 6ft
  • h = height = 5ft
  • π = 3.14

3.14 x 6 x √(36 + 25) = 147ft²

<h3>What is the total surface area of the figure ?</h3>

Total surface area of the cylinder : πr(r + 2h),

(3.14 x 6) x (6 + 40) = 867ft²

Total surface area = 867 + 147=  1014ft²

You took 6 math quizzes. Your scores are: 89, 96, 92, 84, 94, 100. Mrs. Edwards gave you the choice to pick the mean, median, mo
Alex

Answer:

Median. It has the highest grade.

Step-by-step explanation:

Mean: 92.5

Median: 93

Mode: no  mode (all numbers occur only once)

Range: range is 11 (this would be a terrible grade)

Because the median has the highest grade, you would want to pick it.

If you want/ need me to show work or explain just let me know

Also, if my answer helps please consider giving me brainliest.
