You may solve the following exercise using a graphing calculator. (Round your answers to one decimal place.)

After a sale has been advertised for t days, the proportion (or percentage) of shoppers in a city who have seen the ad is 1 − e^−0.05t.

(a) How long must the ad run to reach 60% of the shoppers?

days

(b) How long must the ad run to reach 70% of the shoppers?

days

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

exactly you go it

step-by-step explanation:

the answer is 0.8in^2

hope you get it down chief.
