Answer:

30 ft

Step-by-step explanation:

This is a problem of similar triangles.

         | \

         |    \

     h  |        \

         |          \

         |         5|\

         |           | 4\

          <----24---->

      tree     man

The height of the man is 5 ft.

The shadow of the tree is 24 ft.

The shadow of the man is 4 ft.

We have similar triangles, so the lengths of their sides are proportional.

h/24 = 5/4

Cross multiply.

4h = 24 * 5

Divide both sides by 4.

h = 6 * 5

h = 30

Answer: 30 ft

Compare the line passing through the points (–2, –9) and (4, 6) to the line given by the equation y = 25x – 4.
elena-s [515]

Answer:

D. They have the same y-intercep

Step-by-step explanation:

Before the comparison will be efficient, let's determine the equation of the two points and the x intercept .

(–2, –9) and (4, 6)

Gradient= (6--9)/(4--2)

Gradient= (6+9)/(4+2)

Gradient= 15/6

Gradient= 5/2

Choosing (–2, –9)

The equation of the line

(Y+9)= 5/2(x+2)

2(y+9)= 5(x+2)

2y +18 = 5x +10

2y =5x -8

Y= 5/2x -4

Choosing (4, 6)

The equation of line

(Y-6)= 5/2(x-4)

2(y-6) = 5(x-4)

2y -12 = 5x -20

2y = 5x-8

Y= 5/2x -4

From the above solution it's clear that the only thing the both equation have in common to the given equation is -4 which is the y intercept

Answer:

(n-5)^2 - (6n-35)=(n-10)(n-6)

-----------

  • n²-10n+25-6n+35 =
  • n²-16+60 = n²- 10n - 6n + 60 =
  • n(n-10) - 6(n-10) =
