What do solving absolute value equations and solving quadratic equations have in common?

Mathematics

Answer:

Step-by-step explanation:

Quadratic equations are equations that when rearranged using the 5 operations can yield a polynomial of degree 2 on one side of the equation and 0 on the other. There are 3 commonly taught methods for solving quadratic equations. These methods are factoring, completing the square, and the quadratic formula. These functions are most commonly used to model projectiles, disregarding air resistance.

When using the factoring method one attempts to write a degree 2 polynomial as the product of two degree 1 polynomials. This method works because if we multiply two degree one polynomials together we find  

For example: When factoring , we want to find two number a, b whose product is 6 and sum to 5. The values of a and b we are looking for are 2 and 3.

The method of completing the square centers around using the five operations to replace the original equation with an equivalent equation of the form  by taking advantage of the fact that

The absolute value function takes the value of a number, regardless of whether it is positive or negative. Some problems that the absolute value is useful for modeling include an object bouncing on the ground.

For example, , since we do not care about the negative sign.

Example: Solve  

Solution: Since the absolute value does not care about whether a number is positive or negative, if  then  or . Then we can solve each equation individually to find that x = 1 or 5.

Part B
Nutka1998 [239]

Answer:

if you are asking what the measure of the other angle is if it's just two angles and they are supplementary, the answer is 145º

Step-by-step explanation:

Supplementary angles would add up to equal 180º.

Angle W, which we already know is 35º.

Let's just call the other angle "x" for now.

1. Since we know the two angles will equal 180º, we can do x + 35= 180

2. Now we have the equation set up, and we can subtract 35 from each side

3. Once you subtract 35 from each side, you get x = 145º, which is your answer!

A group of hikers walks 3 miles east and then 1 mile north. After taking a break, they then hike 4 miles east to their final des
geniusboy [140]

Answer:

The vector that describes their hike from their starting position to their final destination is \vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi].

Step-by-step explanation:

In this problem we assume that orthogonal axes coincide with the north and east. We proceed to translate each sentence from statement into vectorial equations:

(i) <em>A group of hikers walks 3 miles east and then 1 mile north:</em>

\vec r_{A} = 3\,\hat{i}+1\,\hat{j}\,\,\,[mi]

(ii) <em>After taking a break, they then hike 4 miles east to their final destination:</em>

\vec r_{B} = 4\,\hat{i}\,\,\,[mi]

The vector that describes their hike from their starting position to their final destination is the sum of the vectors deducted above. That is:

\vec r = \vec r_{A}+\vec r_{B}  (1)

\vec r = (3\,\hat{i}+1\,\hat{j})+4\,\hat{i}\,\,\,[mi]

\vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi]

The vector that describes their hike from their starting position to their final destination is \vec r = 7\,\hat{i}+1\,\hat{j}\,\,\,[mi].
