The common ratio is the common multiple of consecutive terms, usually denoted as "r" for the common ratio. Mathematically the common ratio is a constant that one finds when any term is divided by the term preceding it, in this case:

r=128/32=32/8=8/2=4

So the common ratio is 4.

Factor completely, then place the answer in the proper location on the grid.<br><br> a^6 - 25b^2

Solnce55 [7]

This is the difference of 2 squares

square root of a^6 = a^3
and square root of 25 b^2 = 5b so we get

(a^3 + 5b)(a^3 - 5b)

Thats the answer

The headlights of an automobile are set such that the beam drops 3 in for each 32 ft in front of the car. What is the angle (giv

Anastaziya [24]

Answer:

0.4476 degrees.

Step-by-step explanation:

Let θ be the angle between the beam and the road. The given values form a right triangle with the distance that the beam drops ( h=3 in) being the side opposite to θ and the distance in front of the car (x=32 ft or x=384 in) being the side adjacent to θ.

Therefore, θ is given by:

$tan^{-1}(\theta) = \frac{h}{x}\\tan^{-1}(\theta) = \frac{3}{384}\\ tan^{-1}(\theta) = \frac{1}{128}\\\theta=0.4476^o$

The angle between the beam and the road is 0.4476 degrees.
