Answer:

Initial Amount=1

Decay Factor=0.99987

Decay Rate=0.013%

Step-by-step explanation:

If P = 0.99987ᵃ

I. Initial amount

The initial amount is when a=0

P = 0.99987⁰ = 1

The Pressure at Sea Level=1

II. Decay factor

This is like the decay constant. From the model, P = 0.99987ᵃ, the decay constant/factor is 0.99987.

III. Decay Rate = 1-0.99987 = 0.00013

Expressed in Percentage = 0.013%

Answer:

The answers to the question are as follows

Initial a amount = 1

Decay Factor =0.99987

Decay rate = 1-0.99987 = 0.00013

Step-by-step explanation:

We have the formula for exponential decay given by

y = a(1-b)^t

In the above we have  (1+b)  = Decay factor

a = Initial amount

b =  rate of decay

t = time

Comparing y = a(1-b)^t , with the function in the question, we have

a(1-b)^t≡ 0.99987^a

Therefore, a ≡ 1,

1 + b ≡ 0.99987 and

x ≡ a

Therefore we have

Initial amount = 1

Decay/growth factor = 0.99987

But rate of decay = b = 1-(1-b) =b

Therefore Rate of Decay = 1 - 0.99987

many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Miriam owes $750 on a cre
mash [69]
The answer is E.

First you need to find the rate. You must divide 1.8 by 100

1.8/100 = .018

Then add 1.

.018 + 1 = 1.018

Then times the starting amount with 1.018. The starting amount 750

750(1.018) = <span>763.5.
</span>As you can see, in option E that is the 2nd number.

Now we must find the next number.

You will do 750(1.018)^x

x represents the time.

763.5 was the first month.

750(1.018)^2 is the 2nd month.

750(1.018)^2 = <span>777.244 which is the 3rd number in option E</span>

, 80 POINTS Find k so that P(k,0) is equidistant from points A(1,2) and B(2,5).
blagie [28]

Answer:

P(1.5, 3.5)

Step-by-step explanation:

We need to find the average of the x and y coordinates. We do this by adding the two values, then dividing by two:

P(x1 + x2/ 2, y1 + y2/2) = P(1 + 2/ 2, 2 + 5/ 2) = P(3/2, 7/2) = P(1.5, 3.5)

These are our coordinates!
