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
A = lw
20.4 = 12w
1.7 = w
P = 2 (l + w)
P = 2 (12 + 1.7)
P = 2 (13.7)
P = 27.4 m
Both are solid lines so its neither B or D
It is C because The first inequality in A would shade down when the graph shades up
The total angles in a polygon is 180 (n -2) where n is the number of sides.
A traingle has 3 sides. using the formula 180 x (3-2) = 180
So
X + Y + Y = 180
X + 2Y = 180 ...eq1
A pentagon has 5 sides, using the formula
180 x (5-2) = 540.
All the Y adds up to 540.
10Y = 540
Y = 54.
Use Y = 54 and sub into eq1
X + 2(54) =180
X = 180 - 2(54)
X = 180 -108
X =72
So X is 72
and Y is 54
Just multiply 3.5 inches times 30 miles to get 105 miles.
