I’m not sure if this is right. But I think it’s 29
x=4
8(4) -3
32-3=29
Answer:
the reflection is across the x- axis
Step-by-step explanation:
if you see that the y's in the second graph are negative then the reflection is across the x-axis
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
Answer:
14) 21.136505024965 m
15) 43.076759215619 km
Step-by-step explanation:
14)
let h be the height of the lighthouse:
tan(41.3) = 18.7/h
Then
h = 18.7÷tan(41.5)
= 21.136505024965 m
………………………………………
15)
90-71.4 =18.6
Let s be the distance that the plane flew
towards the south:
tan(90 - 71.4) = s/128
Then
tan(18.6) = s/128
Then
s = tan(18.6)×128
= 43.076759215619 km
