What is the square root of -1​

Mathematics
1 answer:
Romashka [77]3 years ago
3 0

Answer:

i

Step-by-step explanation:

Now, before you think I'm just stealing points, let me explain. The square root of a number is the number that, if you multiply it by itself, it equals that number. The square root of 4 is 2, because 2 * 2 = 4.

Also, a negative number times another negative number, is a positive number. -2 * -2 = 4

With both of those true, then what number could be multiplied by itself to equal a negative number? i.

i is a weird number that I don't really know how to explain all that well. I am sorry, but that is all that I can give you. i is very complex and has various different equivalents, and different meanings, but i is equal to \sqrt{-1}.

Hope that this helps!

Answer:

  (3.5, 17)

Step-by-step explanation:

It would be nice to see the whole graph, so we can see where the functions cross.

Without that information, we can still eliminate unreasonable choices.

A) the quadratic at y=3.5 is well above the exponential

B) the most likely choice (3.5, 17)

C) at x=-8, the quadratic is above the exponential

D) neither graph goes anywhere near y = -8

The kite is directly 35.707 yards high above Erika

Step-by-step explanation:

Given scenario forms a right triangle where the length of string is the hypotenuse and the distance between Mary and Erika is the base.

So

H = 50\ yards\\B = 35\ yards

We have to find the perpendicular

Using pythagoras theorem,

H^2 = B^2 + P^2

Putting the values

(50)^2 = (35)^2 + P^2\\2500 = 1225 + P^2\\P^2 = 1275\\

Taking square root on both sides

\sqrt{P^2} = \sqrt{1275}\\P= 35.707

Hence,

The kite is directly 35.707 yards high above Erika
