A video game uses the quadratic equation h equals space minus 16 t to the power of 2 space end exponent plus space 64 t space pl

stellarik [79]

Answer:

Step-by-step explanation:

Given

h varies as

$h=-16t^2+64t+190$

Above h represents the height of object at any instant t

For example at t=0

h=190 ft

At t=1 s

h=-16+64+190=238 ft

For maximum height differentiate h w.r.t time

$\frac{\mathrm{d} h}{\mathrm{d} t}=-16\times 2\times t+64$

Put $\frac{\mathrm{d} h}{\mathrm{d} t}=0$ to get maximum height

$-32t+64=0$

t=2 i.e. at t= 2 s h is maximum

h at t=2 s

$h=-16\times 2^2+64\times 2+190=254 m$

Given the following constants for a standard form quadratic equation, determine the nature of its roots.

Firdavs [7]

Given that

a=3

b=3

c=2

The number and kind of roots depend on the Discriminant of the equation .

Formula for the Discriminant ,D is given by this

$D = b^{2} -4ac$

So using the formula we get that

$D = 3^{2} -4*3*2\\D=9-24\\D= -15$

Concept is that if the Discriminant is negative then no real solution is possible ,

here using the Discriminant formula we have got the Discriminat value as -15 which is a negative number so we say there is no real solution for the given information .

Hence <u><em>C</em></u> is the correct option .
