What is the formula for exponential growth in cost?

Back

The formula for exponential growth in cost is r(x) = a(b)^x, where 'a' is the initial cost and 'b' is the growth factor.

Front

What does the term 'quadratic equation' refer to?

What is the conversion factor from miles to feet?

Back

1 mile = 5280 feet.

Front

How do you convert speed from miles per hour to feet per minute?

Back

To convert speed from miles per hour to feet per minute, use the conversion factors: multiply by 5280 (feet per mile) and divide by 60 (minutes per hour).

Front

What is the formula for linear growth in cost?

Back

The formula for linear growth in cost is C(t) = C_0 + rt, where C_0 is the initial cost, r is the rate of increase, and t is time.

Front

What is the relationship between exponential functions and their growth rates?

Back

Exponential functions grow at a rate proportional to their current value, meaning as the function increases, the rate of growth also increases.

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, for any two points x1 and x2 where x1 < x2, the value of the function at x1 is less than the value at x2.

Front

What is a ratio?

Back

A ratio is a comparison of two quantities, showing how many times one value contains or is contained within the other.
