Answer:

A) $f(x) = 3x + 3; f(10) = 33$

Step-by-step explanation:

$39 = 3x + 3 \\ \\ 36 = 3x \\ \\ 12 = x$

$15 = 3x + 3 \\ \\ 12 = 3x \\ \\ 4 = x$

* $33 = 3x + 3 \\ \\ 30 = 3x \\ \\ 10 = x$

Answer:

t = 25.1seconds

Step-by-step explanation:

X(t)= 16cos75°t

Y(t)= 6 + (Vosin75°t - 16t^2)

Converting 78 yards to feet :

1 yard = 3 feet

78feet =?

78×3=234 feet

Y(t)= number of feet above the ground at t seconds

VoCos75° t = 234

t = 234/(VoCos75°)

At this time,4 = y(234/VoCos75°)

4 = 6 + VoSin75°(234/VoCos75) - 16(234/VoCos75°)^2

Vo= 140.66ft/s

Time,t= 234/(140.66× Cos75°)

t = 25.087seconds

t= 25.1 seconds (1 decimal place)
