D = sqrt((6 - (-1))^2 + (-2 - 4)^2) = sqrt(7^2 + (-6)^2) = sqrt(49 + 36) = sqrt(85) units.

A public beach in Florida charges non residents $8 per day for a fishing license and $2.50 per day for live bait. Florida reside

melamori03 [73]

For a non-resident:

$C_{nr}=8d+2.5d=10.5d$

For a resident:

$C_{r}=114+1d$

We want to know the number of days $d$ such that the two costs are equal ie $\{d|C_{nr}(d)=C_{r}(d)\}$

To do this set the two costs equal to each other:

$C_{nr}=C_{r}$

$10.5d=114+1d$

And solve for d:

$10.5d-1d=114+1d-1d$

$9.5d=114$

$d=\frac{114}{9.5}$

$d=12$

The costs will be equal when a resident and a non-resident each use the beach for 12 days.

Explain how to determine it a function is exponential growth or exponential decay. Give an example of each.

kozerog [31]

Answer: Formula is given in the picture Step-by-step explanation: For the exponential growth we have the formula Exponential functions are in the form y = ab^ xIf a is positive and b is greater than 1, then it is exponential growth. If a is positive and b is less than 1 but greater than 0, then it is exponential decay. For Example2 months ago you had 3 mice, you now have 18 shows and exponential growth And Atmospheric pressure (the pressure of air around you) decreases as you go higher shows exponential decay.

These three points are collinear. (3, 6), (-2, -9), (0, -4) True False

mr_godi [17]

Answer:

False

Step-by-step explanation:

to determine if the points are collinear, determine the rate of change(slope) between (-2, -9) and (0, -4) and then the rate of change between (0, -4) and (3,6) and rate of change between (-2, -9) and (3, 6). if the rates are equivalent then the points are all collinear

between (-2, -9) and (0, -4):

m=(y2-y1)/(x2-x1)

=(-4-(-9))/(0-(-2))

=5/2

between (0, -4) and (3,6):

m=(y2-y1)/(x2-x1)

=(6-(-4))/(3-0)

=10/3

because 5/2 does not equal 10/3 the rates of change are not equal and the points are not collinear, do not need to consider slope between (-2, -9) and (3, 6)
