The slope of the given line is 1/3.

The perpendiculars all have the negative reciprocal slope, -3.

<span>A. y + 2 = -3(x-4)

Yes, slope -3.

B. y - 5 = 3(x+11)

No, slope 3.

C. y = -3x - 5/3

Yes, slope -3.

D. y = 1/3 x - 2

No, that's slope 1/3.

E. 3x + y = 7
</span>
That's

y = -3x + 7

Another slope -3, Yes.

The first three terms of a geometric sequence are shown below.

san4es73 [151]

This is a geometric sequence of the form:

a(n)=(x+3)(-2x)^(n-1) because each term is -2x times the previous term...so

a(8)=(x+3)(-128x^7)

a(8)=-128x^8-384x^7

zhuklara [117]

Answer:

270 feet

Step-by-step explanation:

For clarity, the image below represents the problem. Let's call h the height of the tower. Notice that it forms 2 triangles that are similar to side-angle-side. So, we can calculate the higher of the tower by similar triangles:

higher1/base1 = higher2/base2

h/135 = 6/3

h/135 = 2

h = 270 ft
