In order to solve the given problem above, we use

<span>t=<span><span>¬b</span><span>2a</span></span></span>; this would be a much easier method. <span>a=¬16</span> and <span>b=24</span>. We simply plug these values into, followed by simplifying the t value for the time, and then insert this value into <span>h(t)</span> for the height at t. This is one of the ways of determining the maximum of a quadratic function.

I think that using <span>t=<span><span>¬b</span><span>2a</span></span></span> is easiest; <span>a=¬16</span> and <span>b=24</span>. We simply plug these values in, simplify for the t value for the time, and then insert this value into <span>h(t)</span><span> for the height at t.</span>

n = 0

Step-by-step explanation:

Anything to the power of 0 is 1

x^12 is already equal to x^12 so it only needs to be multiplied by 1

So n = 0

Margaret [11]
All the numbers are multiplied by 2 or doubled.

So the missing number after 2 is 4.

After 16 is 32.
