Answer:
x = 88.2
Step-by-step explanation:
The angle at the top of the triangle = 90° - 10° = 80°
and the left side of the triangle is x ( opposite sides of a rectangle )
Using the tangent ratio in the right triangle
tan80° =
= 
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x =
≈ 88.2
The question is relating Rhonda's distance travelled and time taken
If 45 miles = 3 hours
Then, 1 mile = 3/45 hours

Therefore, it will take Rhonda 1/15 hours to travel 1 mile.

Answer:
b=2/3
Step-by-step explanation:
The table is given as:

The exponential function is given in the form

where a is the initial value and b is the multiplicative rate of change
When x=1, y=9, we have:

When x=3, y=4, we have:

Dividing the two equations:

The multiplicative rate of change, b is 2/3.
