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

Answer:
z=3
Step-by-step explanation:
-12=-8z+12
-12-12=-8z
-24=-8z
-24/-8=z
z=24/8
3=z
z=3

Answer:
Step-by-step explanation:
We have given two function f(x) and g(x)
We need to operate 
Substituting the values in the above format we will get
after opening the parenthesis we will get
We will get after simplification the above expression
Addition of these two functions give us a quadratic expression means an expression with degree or highest exponent two.
