<span>A. 30 ft
The formula for the area of a rectangle is width x length = area. Knowing this formula, we can solve for the length by dividing the area by the width. 600 divided by 20 is 30.</span>

Find the constant of variation
From the question, the variation is as follows
Convert variation to equation
Where k represents the constant of variation
Make k the subject of formula;
Multiply both sides by s * t
Divide both sides by p
Substitute the values of p, r, s and t in the above equation
Divide numerator and denominator by 6
Hence, the constant of variation is;
B) lograrithmic
this is obvious since it is increasing at decreasing rate
Step-by-step explanation:
Exponential function: f(x)=250(1.03)^x
Simplify both sides of the equation.
f(x)=250⋅1.03x
Evaluate the function.
250⋅1.03x
Answer:
First Option
Step-by-step explanation:
When we graph the expression, we should see that an infinite amount of y-values work. Since the domain comprises of all working x-values, we have (negative infinity, positive infinity) or all real numbers as our range, since we have an infinite amount of y-value outputs.
