Answer:

sqrt(9) * sqrt(4)

Step-by-step explanation:

sqrt( 9*4)

We know that sqrt(a*b) = sqrt(a) * sqrt(b)

sqrt(9) * sqrt(4)

Answer:

Lets start off by saying that a square root is basically that number multiplied by itself.

Ex: the square root of 9 is 3 because 3 x 3 is 9

the square root of 4 is 2 because 2 x 2 is 4

the square root of 25 is 5 because 5 x 5 is 25

and so on.

so 9 x 4 = 36

the square root of 36 is 6 because 6 x 6 is 36.

the number 6 isn’t on this list here.

your option would be B) because the square root is 9 is 3 and the square root of 4 is 2.

3 x 2 = 6

B is equivalent to the equation in the problem.

So your correct answer is B. Please hit the thx button and mark me brainliest if this helped :)

Answer:

y = (x-0)^2 + (-5)  ⇒ y = x^2 - 5

Step-by-step explanation:

The general vertex form of the parabola  y = a(x - h)² + k

Where (h,k) is the coordinates of the vertex.

As shown at the graph the vertex of the parabola is the point (0, -5)

So,

y = a(x-0) + (-5)

y = ax^2 - 5

To find substitute with another point from the graph like (1,-4)

So, at x = 1 ⇒ y = -4

-4 = a * 1^2 - 5

a = -4 + 5 = 1

<u>So, the equation of the given parabola is ⇒ y = x^2 - 5</u>
