given line segment jl with j(8 -8) and l(-16 -2) find the coordinates of K if K divides line segment JL two-thirds of the way fr
Masja [62]

Answer:

  • (-8, -4)

Step-by-step explanation:

<h3>Given</h3>
  • Line segment JL with J(8, -8) and L(-16, -2)
<h3>To find</h3>
  • Coordinates of K if K divides JL two-thirds from J
<h3>Solution</h3>
  • JK = 2/3JL

<u>Coordinates of K</u>

  • x = 8 + 2/3(-16 - 8) = 8 + 2/3(-24) = 8 - 16 = - 8
  • y = -8 + 2/3(-2 - (-8)) = -8 + 2/3(6) = -8 + 4 = - 4
  • K = (-8, -4)

This is a gardener's floor plan of their backyard. Enter the amount of grass, in square yards
BaLLatris [955]

Answer:

39 yd^2

Step-by-step explanation:

First, we must divide the shape into quadrilaterals. The best, and easiest, way to do this is to cut along the line in the middle, below the lower 2 yd mark. This will give us a 1 yard by 3 yard rectangle, 4 yard by 8 yard rectangle, and 2 yard by 2 yard square. The next thing to do is to find the area of each location of the backyard using the A = l x w equation. 1 x 3 =  3, 2 x 2 = 4, 4 x 8 = 32. The final step is to add these individual areas, giving us 39 square yards.

Find the length of the right triangle’s other leg. Round to the nearest tenth. SHOW YOUR WORK. leg = 9 ft hypotenuse = 12 ft
GREYUIT [131]

Use the Pythagorean Theorem: a^2 + b^2 = c^2. a and b are the legs, and c is the hypotenuse. Plug in your numbers: 9^2 + b^2 = 12^2

81 + b^2 = 144. Subtract 81 from 144 : b^2 = 63. Now take the square root of 63, which is 7.9. 7.9 ft is your answer.

BRAINLIEST! what are the next 2 terms in the geometric sequence?<br> a1=2,r=-3
LenKa [72]

Answer:

The next two terms after a1 is

-6 and then 18

Step-by-step explanation:

Geometric sequence means your pattern for the terms is multiplication by the same number.

So a1 is the first term and r is your common ratio.

The common ratio is what you are multiplying by each time to figure out the next term.

So the geometric sequence goes like this:

a1 ,  a1*r , (a1*r)*r or a1*r^2 , a1*r^3 ,....

So anyways you have

first term a1=2

second term a2=2(-3)=-6

third term a3=-6(-3)=18

And so on...

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
