Answer:

x = 9√3

y = 18

Step-by-step explanation:

Using SOH CAH TOA

sin (thita) = Opp/hyp

sin 30 = 9/y

y = 9/sin 30

y = 9/0.5

y = 9×2

y = 18

Cos (theta) = Adj/hyp

cos 30 = x/18

x = 18×cos30

x = 18 × √3/2

x = 9√3

Aubrey and Charlie are driving to a city that is 120 mi from their house. They have already traveled 20 mi, and they are driving
Zarrin [17]

Answer:  The function that models the distance they drive is

f(x) = 50x + 20 where x is the time in hours

reasonable domain:  0 ≤ x ≤ 3

Step-by-step explanation:

examples:

95 = 50(1.5) + 20 After driving another hour and a half, they will have driven a total of 95 miles.

120 = 50(2) + 20  This means that after 2 more hours they will reach their destination.

There is a little ambiguity in the question. The function could be written as if they are starting out.  f(x) = 50t  

20 = 50(.4)  At 50 mph it took .4 hours to go 20 miles.

120 = 5(2.4)  The whole trip took 2.4 hours.
