Solve the equation by using square roots. 2 x 2 − 9 = 11
VashaNatasha [74]

Answer:

x = ± \sqrt{10}

Step-by-step explanation:

Given

2x² - 9 = 11 ( add 9 to both sides )

2x² = 20 ( divide both sides by 2 )

x² = 10 ( take the square root of both sides )

x = ± \sqrt{10} ← exact solutions

Use the drawing tools to graph the distinct real zeros of the polynomial function p(x) = x3 - 2x2 - 4x2 + 8x.
vodomira [7]

Answer:

Step-by-step explanation:

My drawing tool is Desmos. It can be used at no cost.

the graph will not work unless you combine -2x^ and -4x^2 to give - 6x^2.

If you try and graph it as given, you get a straight line going for quadrant 4 to quadrant 2.

But you will note that when you make the addition of the 2 middle terms, it gives you the graph that I have enclosed, which is the one you should expect. I'm wondering why you get a straight line when you try and graph what you were given.

Need help with 15, 16, 17 and 18. Please provide an explanation. Also list in least to greatest. Thank you in advance!
EleoNora [17]
15. 99%, 0.95, 5/9, 9.5%
Make all decimals: .99, .95, .55, .095
List: Zero is less than 9 or 5 so it's first than 5 and than 9, you have two 9's so 5 is less than 9: .095, .55, .95, .99

16. 3/8, 50%, 0.35, 38%
Same steps: .375, .50, .35, .38
3 is less than 5 and 5 is less than 8 or 7 so: .35, .375, .38, .5

And do the same thing for the other two problems :)
