Answer:
Second choice
Step-by-step explanation:
To find inverses, we follow the steps:
1. exchange variables x and y
2. solve for y in terms of x.
The resulting function is the inverse.
Take case 2 as an example:
f(x) = y = 2x-3
1. exchange x and y : x=2y-3
2. solve for y: x+3=2y => y=(x+3)/2 = g(x)
Since the inverse of f(x) is g(x)=(x+3)/2, the second choice is the answer.
Answer:
D= 49/8
Step-by-step explanation:
Cross-multiply.
(2d-5)/2 = (5d+2)/9
(2d−5)*(9)=(5d+2)*(2)
18d−45=10d+4
Subtract 10d from both sides.
18d−45−10d=10d+4−10d
8d−45=4
Add 45 to both sides.
8d−45+45=4+45
8d=49
Divide both sides by 8.
d= 49/8
So the answer is 49/8

You need to <span>draw the diagram to understand the problem easily. Teh diagram will show the right triangle, acute angle with the base 7º, height is 663 m, and "x" is the base of the triangle.
using the tangent ratio:
tan</span>Θ = opposite / adjacent
<span>
tan7º = 663 m / x
x = 663 m / tan7º
x = 5,399.7 m
change m to km. 1,000 m = 1km
5,399.7m * 1km/1,000 m = 5,399.7 km/1000 = 5.3997 km or 5.4 km
B. 5.4 km </span>
