Mathematics
1 answer:
otez555 [7]3 years ago
6 0

Answer:

14

Step-by-step explanation:

In a triangle, the midline joining the midpoints of two sides is parallel to the third side and half as long, so

FB = EC/2

2x - 6 = 44/2

2x - 6 = 22

2x = 22 + 6

2x = 28

x = 28/2

x = 14

Answer:

10

Step-by-step explanation:

Use the distance formula.

d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

We have x1 = 2; y1 = 0; x2 = -6; y2 = 6.

d = \sqrt{(-6 - 2)^2 + (6 - 0)^2}

d = \sqrt{(-8)^2 + 6^2}

d = \sqrt{64 + 36}

d = \sqrt{100}

d = 10

Find an equation of the curve that passes through the point (0, 4) and whose slope at (x, y) is x/y.
jolli1 [7]
1/2y^2=1/2x^2+8. The curve's slope at (x,y) is x/y, so dy/dx=x/y. To solve this differential equation, rearrange it to: y*dy=x*dx, and by integrating both sides, we get 1/2y^2=1/2x^2+C (some constant). Plug in (0,4) into this equation, 8=0+C, so C=8. The curve's equation is 1/2y^2=1/2x^2+8.

What is the length of the longest side of a triangle that has vertices at (7, 6), (7, 1), and (-5, 6)?
iren2701 [21]

Answer: The Answer is going to be B.

Step-by-step explanation:

We can find the distance between each pair of points using the distance formula Sqrt((x1-x2)^2 + (y1-y2)^2),(x1 and x2 are the x ordinates of each point, and y1 and y2 are the y ordinates. Sqrt stands for square root, and ^2 is to the power of two.

Using this we can find the side between 7,6 and 7,1 is 5.

The side between 7,1 and -5,6 is 13

The side between 7,6 and -5,6 is 12

After using the formula we can conclude the side between 7,1 and -5,6 is the longest, and it equals 13. Therefore the answer is B.
