Answer:

It's <u>option A. ± </u>√6<u>0</u>

Step-by-step explanation:

x^2  = 60

here ^2 will move to the other side and when it does it'll become a square root to 60.

so, x = √60

now, the answer in its simplified form would be 2√15 and -2√15.

The answer of this square root will be negative as well as positive, so, ±√60.

Daniel dives into a swimming pool. The height of his head is represented by the function h(t) = -8t2 - 28t + 60, where t is the
8_murik_8 [283]
So, h(t) is how far is Daniel's head from the surface of the water, namely the surface itself is when the height is nill, so his head is at the surface and the height of it is just 0, thus h(t)  = 0.  Namely, what is "t" when h(t) is 0?

\bf h(t)=-8t^2-28t+60\implies \stackrel{h(t)}{0}=-8t^2-28t+60&#10;\\\\\\&#10;0=-2t^2-7t+15\implies 2t^2+7t-15=0\implies (2t+3)(t-5)=0&#10;\\\\\\&#10;\begin{cases}&#10;2t+3=0\implies 2t=-3\implies &t=-\frac{3}{2}\\\\&#10;t-5=0\implies &\boxed{t=5}&#10;\end{cases}

clearly the seconds cannot be a negative unit, so is not -3/2.
