Answer:

  45

Step-by-step explanation:

The equation is that of a parabola in vertex form.

  y = a(x -h)^2 +k

where 'a' is the vertical scale factor and (h, k) is the vertex.

Comparing this to the given function, you find ...

  a = -5

  h = 1

  k = 45

The negative value of 'a' tells you the parabola opens downward, so the y-value of the vertex is the maximum value of the function: 45.

Write the equation like this: 275 + 55h = 440. Then, subtract 275 on both sides making the left side cancel out and the right side 165. Lastly, divide 55 on both sides to get h all by itself. The solution is h = 3. You must drive 3 hours longer to reach your destination.

Which of the following numbers are divisible by 3
Natalija [7]

If you add up all of the digits in the number, and if that number you get is able to be divided by 3, the original number is good to divide by 3.

For example: 618

You add 6+1+8 and get 15

Take 15 and divide by 3

You get a whole number, 5

Therefore, 618 can be divided by 3
