Answer:
A general exponential equation is written as:
y = a*(b)^x
Where:
y represents the amount of something as a function of the variable x, where x is an independent variable.
a is the initial amount, this is, the value of y when x = 0.
b is the rate of growth, this defines how much changes the value of y as x increases.
Answer:
Option 1
Step-by-step explanation:
Given in the picture is a right triangle
One leg is x and hypotenuse is 8
The angle opposite leg x is given as 20 degrees
Recall the formula for trignometric ratio

Here opposite side of 20 is x and hypotenuse =8
Hence 
So option I is right.
Answer:
15 is the distance
Step-by-step explanation:
1/5 of 14 inches is 2.8
so the scale drawing of the ship is 2.8 inches long
