How do you factor polynomials?

Mathematics
1 answer:
choli [55]3 years ago
6 0

Answer:

In mathematics, factorization or factoring is the breaking apart of a polynomial into a product of other smaller polynomials. If you choose, you could then multiply these factors together, and you should get the original polynomial (this is a great way to check yourself on your factoring skills). One set of factors, for example, of 24 is 6 and 4 because 6 times 4 = 24. When you have a polynomial, one way of solving it is to factor it into the product of two binomials.

You have multiple factoring options to choose from when solving polynomial equations:

For a polynomial, no matter how many terms it has, always check for a greatest common factor (GCF) first. Literally, the greatest common factor is the biggest expression that will go into all of the terms. Using the GCF is like doing the distributive property backward.

Find all the missing angles. All answers are assumed to be in degrees.
Vlad [161]

Answer:

1. 63
2. 49°
3. 87°
4. 44°

Step-by-step explanation:

First, I worked out Angle 3 as this angle and 93° are on a straight line:

So I made an equation:

180 = 93 + Angle 3

180-93 = Angle 3

87 = Angle 3

Now we have enough information for Angle 4 as angles in a triangle add up to 180

87 + 49 + Angle 4 = 180

Angle 4 = 180 - 87 - 49

Angle 4 = 44
Using the rule of opposite angles:
I worked out that Angle 2 must be 49 as well.
This is now enough information to work out Angle 1  as angles in a triangle add up to 180
49 + 68 + Angle 1 = 180

Angle 1 = 180-49-68

Angle 1 = 63

Grear Tire Company has produced a new tire with an estimated mean lifetime mileage of 36,500 miles. Management also believes tha
antiseptic1488 [7]

Answer:

Step-by-step explanation:

standard deviation σ =5000

Mean μ = 36500

X = 30000

Probability that tire fails to reach 30000 miles

P(< 30000) = P( z < (30000-36500) / 5000 )

= P ( z < - 1.3 )

= .0968 ( from z table )

refund per mile = .01

refund for 30000 mile = .01 x 30000 = 300

expected cost of promotion

= 300 x .0968

= 29.04

b )

refund of $50 is equivalent to shortage of milage by 50 / .01 = 5000 miles

Probability of miles less than 30000 - 5000 = 25000

P ( X < 25000 ) = P ( z < (25000 - 36500) / 5000 )

P ( z < - 2.3 )

= 0.0107 Answer .
