It looks like for all of these we will be using the Pythagorean theorem.

If you don't know what this is or how to apply it, go to the website "Khan Academy" and watch his video(s) on it. I would suggest going to that site whenever you don't understand something in math :)

I'll just be giving you the answers and won't explain what I'm doing, but please do go to Khan Academy to find out how to do it on your own!!

1) a = 12.5, b = 5.7, c = 13.7.
2) 24
3) 19.2
4) 6.4
5) 18.7

### Plz help.......................

Let's use the slope intercept form of a line which is:

y=mx+b where m=slope and b=y-intercept.

Mathematically m=(y2-y1)/(x2-x1) and the y-intercept is just the value of y when x is equal to zero, where the line intercepts the y axis...

First you want to find the slope by finding two clearly identifiable points on the graph...I'll pick (4,4) and (0,1), now we can calculate the slope or "m"...

m=(4-1)/(4-0)=3/4 so now we can say our line is:

y=0.75x+b, using point (4,4) we can now solve for b.

4=0.75(4)+b

4=3+b

b=1 so the line is"

y=0.75x+1

### PLEASE ANSWER!!!! You have \$5 for lunch. You bought turkey sandwich for 2.25. A. Write an inequality that represents how much more money you can spend. B.Solve your inequality. plz help will mark best answer as brainliest again plz.

⇒ x < \$2.75

Step-by-step explanation:

Amount of money spent on lunch = \$5

Amount of money used in buying turkey sandwich = \$2.25

Let the money left for spend be x

So, The inequality that represents how much more money you can spend is given by :

x < 5 - 2.25

This is the required inequality

Now we need to solve this inequality.

⇒ x < \$2.75

Hence, This is the inequality which is the solution of the resultant inequality.

QUESTION POSTED AT 17/10/2019 - 07:17 AM

### Solve for x. PLZ WAIT FOR THE PHTO TO UPLOAD

6x² - 5x + -21 = 0

Because this whole equation equals zero, we must simply factorize the first half of the equation, or the left side.

(3x - 7)(2x + 3) = 0

I was never really taught a specific way to factorize, so I usually just guess and check when factorizing. It usually takes a long time, it always gives you the tight answer.

Then, take each equation and make it equal zero.

3x - 7 = 0 AND 2x + 3 = 0

3x - 7 = 0

3x = 7

Divide both sides by 3.

x = 7/3

Now, we do our second equation.

2x + 3 = 0

Subtract 3 from both sides.

2x = -3

Divide both sides by 2.

x = -3/2

So, x = 7/3 AND x = -3/2

~Hope I helped!~

For x=1, we have:
8.904 *1 < 18.037
8.904 < 18.037
For x=2, we have:
8.904*2 < 18.037
17.808 < 18.037

We could see the solution that the greatest possible value of x is 2.

### Plz help fast Thank you

Hello!

So first off, let's define what a median is: in the list of answers (listed from least to greatest) the number i the middle is the median.

Just like I said, line up the numbers in order of smallest to largest:
12, 14, 14, 14, 15, 16, 16, 18, 18, 19, 21, 22

Now find the number in the middle. It should be 16.

*Just a note for the future: when there's an odd number of integers, the median will just be that number in the middle. Example: 1,4,5; 4 is the median. Now, if there are an even number of integers, the median will be the average between the two middle numbers. Example: 1,4,5,7; the two numbers in the middle are 4 and 5. Take the average between the two (4+5)/2 and you would get 4.5*

2) write the quotient of each number by the number before & notice the value:

49/70= 0.7
34.3/49 = 0.7
24.01/34.3 =0.7
16.0807/24.01 = 0.67 ≈0.7
You notice this is a geometric progression with r 0.7
The last term in a GP =ar^⁽ⁿ⁻¹⁾

3) Domain and Range of this function:
Last term = a₁.rⁿ⁻¹. let last term be y==> f(n) = y =70(0.7)ⁿ⁻¹
or f(n) = y = 70(0.7)ⁿ / 0.7==> f(n) = [(0.7)ⁿ ]/ 100.
This is a decreasing exponential function where the coefficient
raised to n is < 1.
The domain is for all n>= 0.
When n→∞, f(n)→0; For n=0==>f(n) =70. So the range of f(n) is:<=70
