The golden years senior citizen center uses a phone tree to announce when the center will be closed for poor weather. when each person receives a phone call, that person has a list of three more people to call. the function c approximates the total number of calls made after m minutes since the start of the phone tree. c(m) = 3/2 * (3 ^ (m/10) - 1) approximately how many minutes will it take for the number of calls to reach 363?

50 Minutes.

Step-by-step explanation:

The function c approximates the total number of calls made after m minutes since the start of the phone tree.

We need to find the number of minutes after which the total number of calls will 363.

Substitute c(m)=363 in the given function.

Multiply 3/2 both sides.

Add 1 on both sides.

On comparing both sides we get

Multiply both sides by 10.

Therefore, the total number of calls will 363 after 50 minutes since the start of the phone tree.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
