Answer:
About 879.877
Step-by-step explanation:
To find f,
f(13) = 45,000(0.9)^13
13f = 45,000(0.25418658283)
13f = 11438.3962274
f = 879.877

Answer:
Step-by-step explanation:
In the given triangle
With reference angle A
perpendicular (P) = 3
hypotenuse (h) = 5
So sin A = p/h = 3/5
and
With reference angle C
perpendicular (p)= 4
hypotenuse (h) = 5
Sin C = p/h = 4/5
hope it helps :)
The answer would be 15 but i am not sure what the problem says her answer is. if it is not 15 then her answer is wrong
