X2 - 6x + 9<br> help solve
Ulleksa [173]

Answer:

3

lazy approach was with a graphic plotting program, but you can also calculate it. with the pq-formula.

p = -6

q = 9

x = -p/2 +- sqrt( (p/2)² - q)

x = -(-6)/2 +- sqrt ( (-6/2)² - 9)

x = 3 +- sqrt(9-9)

x = 3 +- sqrt(0)

x = 3 +- 0

x = 3

Question 2 Multiple Choice Worth 5 points)
DerKrebs [107]

Answer:

√20 units.

Step-by-step explanation:

Please see attached photo for diagram.

The other leg of the triangle is x as shown in the attached photo.

Using the pythagoras theory, we can obtain the the value of x as follow:

x² = 4² + 2²

x² = 16 + 4

x² = 20

Take the square root of both side.

x = √20 units

Therefore, the value of the other leg x of the triangle is √20 units

Answer:

Yes

Step-by-step explanation:

With the $875,000 from his input alone he is really close to $1,000,000 and doing simple intrest on the $250,000 is $105,000 a year is he earns 3.5% intrest a month.

So in 5 years he'll have about $1,662,500 using simple intrest but with compound it'd be more like 2mil

Hope this helps!

A quality control manager at a factory selects 7 light bulbs at random for inspection out of every
shutvik [7]

Answer:

350 lightbulbs

Step-by-step explanation:

First find the number of batches made.

20,000 divided by 400 = 50

This means that there are 50 batches in which 7 light bulbs will be selected at random to be inspected.

We can multiply the number of batches to the lightbulbs being inspected.

50 times 7 = 350

Therefore, 350 lightbulbs will be inspected.

Please tell me if I am incorrect :)
