1 Solve for the unknown variable:

Burka [1]

Answer:

Approximately 6.4

Step-by-step explanation:

We can use the pythagorean thereom here, that tells us (a^2)+(b^2)=c^2. C is the hypotenuse, the side opposite from the right angle, while a and b are the other sides. We can insert 5 and 4 as a and b, and solve for c

:(5^2)+(4^2)=c^2

:25+16=c^2

:41=c^2

:sqrt(41)=6.4=c (We square rooted both sides. 6.4 is only rounded to the nearest hundredths place.) Hope this helps!

The sum of squares of numbers is: 13

Step-by-step explanation:

Let x and y be two numbers

Then,

Difference of the squares of the numbers will be:

$x^2-y^2$

Product will be:

$xy$

Given identity is:

$(x^2+y^2)^2=(x^2-y^2)^2+(2xy)^2$

Given values are:

Difference of the squares of the numbers= $x^2-y^2=5$

Product of numbers = xy = 6

Putting the values in the identity

$(x^2+y^2)^2=(5)^2+[2(6)]^2\\=25+(12)^2\\=25+144\\=169$

As we have to only find x^2+y^2

Taking square root on both sides

$\sqrt{(x^2+y^2)^2}=\sqrt{169}\\x^2+y^2=13$

The sum of squares of numbers is: 13

Answer:

1. -3

2. 0

3. .363636

4. Non-recurring Decimal, Recurring Decimal, Decimal Fraction

5. Going in order- irrational, rational, rational, irrational, integer, integer, irrational, integer, irrational, rational, rational.

6. 8

7. 12

8. 20

9. -5

10. False, only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.

11. No, only decimals that never end and never repeat are irrational. a decimal is rational if it can be written as a fraction or ratio of two numbers. for example: .3434343434343434

12. Yes, 9.5 can be written as a simple fraction like this: 9.5 = 192

13. 10,920

14. 40,000

15. 0.0702

16. .003

17. 18000000000 meters

18. 1- 2,000,000,000

18. 2- 3,800,000,000

19. 36, 49. or- So, the square root of 40 will be greater than 6 but less than 7.

20. You can just add the coefficients together. If the exponents are not equal, then you must make them equal by moving one of the decimals.
