BRAINLIEST AND LOTS OF POINTS! Hobbies The height above the ground in meters of a model rocket on a particular launch can be modeled by the equation h = -4.9t2 + 102t + 100, where t is the time in seconds after its engine burns out 100 m above the ground. Will the rocket reach a height of 600 m? Use the discriminant to explain your answer.

1) State the discriminant and show your work to show how you found the discriminant.

2) Based on your discriminant, will the rocket reach 600m?

repeat the question

step-by-step explanation:

the answer is c

hope this !

the value of v.w= -12.

step-by-step explanation:

we are given three vector r,v and w as:

r = < 5, -5, -2> ; v = < 2, -8, -8> ; w = < -2, 6, -5>

we know that r,v and w could also be represented as:

r=5i-5j-2k

v=2i-8j-8k

and w= -2i+6j-5k

where i,j and k are the unit vectors of x,y and z-axis respectively.

also we know that it has the following property:

i.i=1 ; j.j=1; k.k=1

and i.=j.i=i.k=k.i=j.k=k.j=0

i.e. when we multiply two vectors or we find it's dot product we need to only multiply the components of x coordinates with each other; y with each other and z with each other.

hence, v.w= (2i-8j- -2i+6j-5k)

                  = 2×(-2)+(-8)×(6)+(-8)×(-5)

                  = -4-48+40

                  = -12

hence, v.w= -12

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
