Can someone help me please.

Mathematics
1 answer:
Brut [27]3 years ago
5 0

Step-by-step explanation:

Realistic domain: t >= 0 (as time is non-negative)

When t = 0,

v(0) = -3(0)² + 73(0) + 50 = 50.

Hence Jennifer started with $5000.

Vertex = -b/2a = -(73)/2(-3) = 73/6.

When t = 73/6

v(73/6) = -3(73/6)² + 73(73/6) + 50 = 494.08.

The maximum value is $49,408.

let's add both x coordinates.

2+7 = 9

Laila is 14 years older than tom. Laila is 5 years younger than Dan. Altogether they have a combined age of 51. How old are they
notka56 [123]
Laila=l
Tom=t
Dan=d

l=t+14
l=d-5
l+t+d=51

In terms of l:
d=l+5
t=l-14

So:
l+l+5+l-14=51
3l+5-14=51
3l-9=51
3l=60
l=20
d=25
t=6

Hope this helps :)
