Answer:
The function show the value of the machinery after "t" years.
So After "4" years... Input "t" as 4 to get its value
f(t) = 12,500 - 1,600(4)
=$6,100
OPTION C IS LEGIT!!!
Yes it is. log(1) and ln(1) both equal zero. But you cannot take the logarithm of 0.
Im pretty sure the answer would be A, B & D
Answer:
It's is A and D.
Step-by-step explanation:
Tan^2 theta cos 2theta
= (sin^2 theta / cos^2 theta )( 2 cos^2 theta - 1)
= 2 sin^2 theta - sin^2 theta / cos^2 theta
= 2 sin^2 theta - tan^2 theta.
Tan^2 theta cos 2theta
= ( 1 / cot^2 theta) * cos 2theta
= cos 2theta / cot^2 theta.
