=5 + 3 + 3 * 15
do multiplication first
=5 + 3 + 45
=8 + 45
=53
ANSWER: 53
Hope this helps! :)
-1 or option c is correct. Use the given functions to set up and simplify f(−2).
Write the equation of the first train: x = 12t
Write the equation of the second train: y = -20t+72, assuming the train one is at the origins when t = 0.
Now solve the equation: 12t=-20t+72,
32t = 72, then t = 2.25 hours. The two train meet after 2.25 hours.
Now the equation of the <span>pigeon is like this: x = 48t.
</span>Then for t = 2.25, we get

The Hyde has flown 108 km when the trains meet.</span>

Answer: Option C is correct!
Step-by-step explanation:
The range of function is [-1,-5] . so first option is incorrect.
Since graph of the function f(x)=-2sin(x) is shifted down by 3 because of -3
therefore option B is incorrect.
Period of the given function is 2pi because here b =1 and period of sinx function is given by
therefore option D is also incorrect
Period of the function f(x) is always absolute value number in front of sinx which is given to be 2 here therefore option C is correct.!
