Answer:

(x + 5)^2 = (5 - 3)^2

Step-by-step explanation:

Given the equation;

x^2 + 10x + 22 = 13

We have;

x^2 + 10x = 13 - 22

x^2 + 10x = -9

Adding half of 10 to both sides and completing the square as usual, we have;

(x + 5)^2 = 5^2 + (-9)

(x + 5)^2 = (5 - 3)^2

ludmilkaskok [199]

The recycling plant processes 480 tons of glass per day.

Step-by-step explanation:

Quantity of glass recycled each minute = $\frac{1}{3}\ tons$

We know that;

1 hour = 60 minutes

Therefore;

Quantity of glass recycled in one hour = $\frac{1}{3}*60=20\ tons$

1 day = 24 hours

Quantity of glass recycled in 24 hours = 24*20 = 480 tons

The recycling plant processes 480 tons of glass per day.

Answer:

Step-by-step explanation:

A^2+B^2=C^2 is the pythagorean theorem to find a missing siede of a triangle.

First triangle on the right:

5^2+B^2=10^2

25+B^2=100

B^2=75

B=8.66025404

B=8.7

Second triangle of left:

3^2+B^2=8.7^2

9+B^2=75.69

B^2=66.69

B= 8.16639455

B=8.2

x=8.2

Solve F(x) for the given domain

PilotLPTM [1.2K]

Answer:

The correct answer is A) 2

Step-by-step explanation:

In order to find this, input 1 into the equation for each value of x that you see.

f(x) = x^2 + 3x - 2

f(1) = 1^2 + 3(1) - 2

f(1) = 1 + 3 - 2

f(1) = 2

What is the 5-digit code?

kvv77 [185]

9514 1404 393

Answer:

4 2 6 1 7 or 1 2 4 3 7

Step-by-step explanation:

4 are correct of 1,3,4,6,7

3 are correct of 0,2,3,6,7

1 is correct of 0,3,6,8,7 -- so not both 3 and 6, meaning 1, 4, 7 are correct

Correct digits so far are 1, 4, 7 and one of {3, 6}. Line 2 tells another is 0 or 2; line 3 tells it is not 0. This adds 2 to the list of correct digits.

This makes the correct digits 1, 2, {3, 6}, 4, 7. We don't know whether the last digit is 3 or 6.

Looking at digits correctly placed, line 2 tells us the code is either ...

_ 2 6 _ 7 or _ 2 _ 3 7

Then line 1 fills in those blanks as ...

4 2 6 1 7 or 1 2 4 3 7

Either of these codes agrees with all of the clues.
