Answer:

-1/3 or 1/2.

Step-by-step explanation:

Second term = ar, the third = ar^2 and the fourth = ar^3.

So we have the equation:

ar + ar^2 = 6ar^3

r + r^2 = 6r^3

6r^3 - r^2 - r = 0

r(6r^2 - r - 1) = 0

(3r + 1 )(2r -1) = 0

r = -1/3, 1/2.

Answer:

The markup rate on each box=41%

Step-by-step explanation:

The markup rate is the additional price that a good is sold at expressed as a percentage. This can be expressed as;

R={(S-C)/C}×100

where;

R=markup rate

S=selling price

C=cost

In our case;

R=unknown

S=$20.50

C=$14.50

replacing;

R={(20.5-14.5)/14.5}×100

R=(6/14.5)×100

R=41.38% rounded off=41%

The markup rate on each box=41%

If a bloodstain has a length of 3.0cm and a width of 1.5cm what is the angle of impact?

zalisa [80]

The angle of impact is 30°

<h3>What is the angle of impact?</h3>

In a bloodstain, the angle of impact can be used to determine the appearance of the resulting bloodstain if the bloodstain has a tail or pattern.

Bloodstain pattern analysis is the study of bloodstains at a scene of the crime in an attempt to reconstruct the events that resulted in the bloodshed.

Mathematically;

$\mathbf{Angle \ of \ impact = sin^{-1} (\dfrac{width \ stain}{length \ stain} )}$

$\mathbf{Angle \ of \ impact = sin^{-1} (\dfrac{1.5}{3.0} )}$

$\mathbf{Angle \ of \ impact = 30 ^0}$
