Compare this function to y=ax^2 + bx + c. You can readily see that a=2, b=0 and c=6.
The x-coord. of the vertex is at x = -b / (2a). Subbing the given values for a and b, we get
x = -(0) / (2(2) = 0. At x = 0, y = 6, so the vertex of this parabola is (0,6). It opens upward.
Answer:
22.6 degrees
Step:
The hypotenuse is 13cm using pythagoras theorem.
Now, finding the smallest angle is by using;
SOH
sin = opposite over hypotenuse
Thus, cos^-1 (12/13)
=22.61
and equals to 22.6 (1d.p)
Answer:
Using formula:

or

As per the given statement:
Distance = 630 miles
Speed = 35 miles per hour
then;
hours
Therefore. 18 hours would it take to travel 630 miles at the rate of 35 miles per hour
