Answer:
C.
Step-by-step explanation:
The function (f+g)(x) is the sum of the two functions:
(f+g)(x) = f(x) +g(x) = (ln(2x) -15) +(3sin(x) -7)
= ln(2x) +3sin(x) +(-15 -7)
(f+g)(x) = ln(2x) +3sin(x) -22
0.05 because 5 is bigger than 4 plus 4 is negative

Answer
Answer:
14.35 grams
Step-by-step explanation:
Amount left, in grams = (970 grams)(1.000 - 0.277)^m, where m is the number of minutes. This is exponential decay.
Amout left = (970 grams)(0.723)^13 = (970 grams)(0.01475), or 14.35 grams
Answer:
When x = 6.
Step-by-step explanation:
WE need to solve the system:
y = - x^2 + 4x + 4
y = -2x + 4
Equating:
- x^2 + 4x + 4 = -2x + 4
0 = x^2 - 4x - 4 - 2x + 4
x^2 - 6x = 0
x(x - 6) = 0
x = 0, 6.
