From last place to first BART was last the it was DERRICK, ALLIE, and CHRIS and ELENA in first. I hope this helps you!
Part 1:
Step 1:
Find the value of G(16)
Using the equation for g(x) =√x, replace x with 16 and solve:
g(16) = √16 = 4
Step 2:
Now using the answer for g(16) replace x in the equation fir f(x) with 4 and solve:
f(x) = x +2
f(4) = 4+2 = 6
Part 2:
following the same steps as part 1:
f(g(x)) would be replacing x in the equation ofr f(x)with the equation for g(x)
f(g(x)) = √x +2
Answer:
504 miles
Step-by-step explanation:
Make a proportion
=
7/12 is 0.5833, so multiply 864 by that to find the number of miles
864(0.5833) = 504
Formula: Distance = rate * time
570 = (R+(R-18))*3
570 = (2R - 18)*3
190 = 2R-16
208 = 2R
R = 104
Eastbound Train: 86mph
Westbound Train: 104mph
Length = 3cm
Volume = length x width x height
