A quantity P is an exponential function of time I, such that P = 160 when t = 6 and P = 150 when I = 4. Use the given information about the function P = Poel to: (a) Find values for the parameters k and Po.
Round your answers to three decimal places.
k=
Po =

Step-by-step explanation:

Perhaps you want to use the points (t, P) = (4, 150) and (6, 160) to find the parameters P0 and k in the equation ...

We know from the given points that we can write the equation as ...

Comparing this to the desired form, we see that ...

So, the approximate equation for P is ...

And the parameters of interest are ...

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
