5 0

Answer:

x=10

Step-by-step explanation:

I think..i tired

 

Divide both sides by 55.

{x}^{2}=-\frac{500}{5}x2=−5500

2

 

Simplify  \frac{500}{5}5500  to  100100.

{x}^{2}=-100x2=−100

3

 

Take the square root of both sides.

x=\pm \sqrt{-100}x=±√−100

4

 

Simplify  \sqrt{-100}√−100  to  \sqrt{100}\imath√100ı.

x=\pm \sqrt{100}\imathx=±√100ı

5

 

Since 10\times 10=10010×10=100, the square root of 100100 is 1010.

Find the reference number of 11pi/9
kotykmax [81]
Unsure of what you mean by "reference number."  

I do recognize that 11pi/9 is in quadrant III.  I suspect that the so-called "reference number" is the acute angle between the end ray of 11pi/9 and pi, or, in more easily comparable numbers, between 9pi/9 and 11pi/9.

That difference is 2pi/9.

75 always do parenthesis first so 5*3=15 so 15x5=75 because 5*5=25 so drop the 5 carry the 2 the do 5*1 which equal 5 then add 2 and that equal 75.

If you took a true “if then” statement and instead a not in each clause the new statement would also be true
Strike441 [17]

Answer:

True

Step-by-step explanation:

  • If it snows today, I will have to go out and clean the driveway.
  • If it does not snow today, I will not have to out and clean the driveway.
  • Without going into p's and q's and true false tables, I believe the negation is also true.
