Answer:

Or if you want with the value of h too.

Step-by-step explanation:

Find the value of h and k by using the formula.

From y = x²-2

Substitute these values in the formula.

Therefore, h = 0.

Therefore, k = - 2.
From the vertex form, the vertex is at (h, k) = (0,-2). Substitute h = 0, a = 1 and k = -2 in the equation.

These type of equation where b = 0 can also be both standard and vertex form.
Answer: x is less than or equal to 35.
Step-by-step explanation:
Yes, because the sum of any 2 sides of the triangle is greater than the value of the third side.
Answer:
<u>1) 187.5ms^2</u>
<u>1) 187.5ms^22) 307.5m</u>
Step-by-step explanation:
1) You can use the formula:
Force = Mass x Acceleration
750 = 4 x a
750 = 4a
750/4 = a
<u>187.5ms^2</u>
2)
For every one second it travels 12.3 meters therefore you can just do 12.3x25 = 307.5m
