Ben dives from a 10-foot platform. the equation h = -16 t 2 27t 10models the dive. how long will it take ben to reach the water?

1 answer:

3 0

So i'm assuming your eqtn is h = -16t^2 + 27t + 10
and we're looking for t = ? when h = 0

=> 16t^2 - 27t - 10 = 0
(16t + 5)(t - 2) = 0

t = 2 and t = -5/16

answer 2 seconds

Answer:

$\huge\boxed{\sf x = \pm \sqrt{7} }$

Step-by-step explanation:

<u>Given function:</u>

$f(x)=x^2-7$

<u>We can also write it as:</u>

$y =x^2-7$

x-intercept is the point where y = 0

Put y = 0 in the above equation

$0=x^2-7\\\\Add \ 7 \ to \ both\ sides\\\\7 = x^2\\\\Take \ sqrt \ on \ both \ sides\\\\\pm \sqrt{7} =x\\\\x = \pm \sqrt{7} \\\\\rule[225]{225}{2}$
