It’s C
You would use cos for this equation
Cos(45)= x/5
5 x cos(45
And when you put that in the calculator you will get that answer C
The domain for N is All integers where n ≥ 1
<u>Solution:</u>
According to statement a1 = 2 and r = 4. This shows that r is greater than 1.
If r is greater than 1 than it includes integers greater than 1 or equal to 1. It does not include all the real numbers because real numbers include negative numbers also.
If starting value is 2, if we put n=0, then we get 2, but if we put a negative value than we would get a number which is not a part of our sequence.
Thus the domain of n is All integers where n greater than or equal to 1
Part A you can figure out that the car is traveling at 50 miles an hour because after every hour the distance decreases by 50
b the average change is 100 miles for every 2 hours, which can be simplified back to 50mph which represents the speed of the car
part C {y=-50x+900| (0,900),...(18,0)
