7q + 2p = 29 & 2p - q =5

faltersainse [42]

Eliminate p terms
times 2nd equation by -1
q-2p=-5
add to 2nd equation

q-2p=-5
7q+2p=29 +
8q+0p=24

8q=24
divide both sides by 8
q=3
sub back

2p-q=5
2p-3=5
add 3
2p=8
divide by 2
p=4

p=4
q=3

A model rocket is launched from the top of a building. The height (in meters) of the rocket above the grown is given by h(t)=-6t

Iteru [2.4K]

Answer:

47.5 Meters

Step-by-step explanation:

Find where the derivative changes from positive to negative (local maximum)

h(t)= $-6t^2+30t+10$

h'(t)= $-12t+30$

Find where the derivative equals zero

Theres no spot where the derivative wont exist because its a polynomial.

-12t=-30

t= $\frac{5}{2}$

Ill stop here because this is a parabola opening down and this is the only spot where there will be a horizontal tangent line so this is the x-coordinate of the vertex. AKA you don't need to test positive and negative on both sides.

Now plug into original equation

h(2.5)= $-6(2.5)^2+30(2.5)+10$

=-37.5+75+10

=47.5
