Number one is the 2nd choice
Answer:
sqrt(13) =x
Step-by-step explanation:
We have 2 right triangles, one on the right and one on the left
The base is 1/2 of 4 or 2 and the height is 3
We can use the Pythagorean theorem to find the hypotenuse
a^2 + b^2 = c^2
2^2 + 3^2 = x^2
4+9 = x^2
13 = x^2
Take the square root of each side
sqrt(13) =x
Answer:
y + 4 = a(x - 7)^2
Step-by-step explanation:
The standard vertex form of a parabola with vertex at (h, k) is
y - k = a(x - h)^2
and if we start with the simplest case, y = a(x)^2 and translate its graph 7 units to the right and 4 units down, we get y - {-4] = a(x - 7)^2, or
y + 4 = a(x - 7)^2
Answer:
2 hours to meet each other
Step-by-step explanation:
Answer:
(x+3)(x-2)
Step-by-step explanation:
We can immediately see that there are roots at x = -3, and x = 2.
Because the website gives us that this in the form of (x + _) (x - _), our anwser is (x+3)(x-2)
oops I just saw your comment. Too late i guess...
