What is the value of k?
seraphim [82]

Answer:

k=2

Step-by-step explanation:

We have got a right triangle LNO with sides = m,4 and 8

By Pythagorean theorem

m^2=4^2 +8^2

Or m^2 = 80  ... i

IN triangle NOM, 4^2 +k^2 = l^2

i.e. 16+k^2 = l^2... i

In triangle LNM, m^2+l^2 = (8+k)^2

Substitute for m^2 as 80,

i.e. 80+l^2 = 64+k^2 +16k  ... iii

From i, l^2 = 16+k^2

Substitute in iii

80+16+k^2 = 64+k^2 +16k

16k = 32 or k =2

The eqution of the diagonal of a parallelogram is 3y=5x +k. The two opposite vertices of a parallelogram are the points (1,-2),
astraxan [27]

Answer:

k = 1

Step-by-step explanation:

Given

3y = 5x + k

Opposite points: (1,-2) and (-2,1)

Required

Find k

First, calculate the midpoint of the opposite points.

(x,y) = 0.5(x_1 + x_2,y_1 + y_2)

This gives:

(x,y) = 0.5(1 -2,-2 + 1)

(x,y) = 0.5(-1,-1)

Open bracket

(x,y) = (-0.5,-0.5)

The equation 3y = 5x + k becomes:

3 * -0.5 = 5 * -0.5 + k

-1.5 = -2.5 + k

Solve for k

k = 2.5-1.5

k = 1
