two polynomials with a constant term of -3 with an explanation, thanks. didn't understand a thing in school.

1 answer:

6 0

All this means is that you can have any polynomial as long as there is a “-3” term in it.

Examples:
x - 3
x^2 - 3
x^3 + 6x - 3

Is 8/5 proportional to 24/15 ?

DiKsa [7]

Hey there!

The answer to your question is, yes, it is

Given:

$\frac{8}{5}$ $and$ $\frac{24}{15}$

To see if they are equal, we can use cross products (see below for information about this, if you don't know what it is). Let us assume they are equal. This would mean that:

$8*15=24*5$

Let's solve it and see if it is true:

$8*15=24*5$

$120=120$

Therefore, they are proportional.

Cross products

WORD DEFINITION:

Given two fractions, you can take the numerator of the first fraction multiplied by the denominator of the second fraction and it should equal the denominator of the first fraction multiplied by the numerator of the second fraction.

ALGEBRAIC DEFINITION:

Given two fractions, $\frac{a}{b}$ $and$ $\frac{c}{d}$ , $a*d$ should equal to $b*c$

Hope it helps, and have a terrificly amazing day!

You are told that in a billiards shot, the cue ball was shot at the eight ball, which was 8 inches away. As a result, the eight

stiks02 [169]

Assumptions: Based on your question is seems like you are trying to find the distance the cue ball was initially at from the pocket from the minimum angle being 90 degrees.

Answer: In this case we can assume the minimum angle that the eight ball had after the collision was 90 degrees and therefore we can use Pythagoras Theorem (only can be used for right triangles). This gives us the length of both sides of that triangle we have constructed which are 8 in. and 6 in.. In the context of our drawing we want to find the hypotenuse of the triangle which would be the initial distance the eight ball was from the pocket (once again being at the most minimum possible angle). a^2=b^2+c^2 . a=sqrt(b^2+c^2) .

Plug in for b and c and you should get that it was greater than 10 in.
