Answer:
- a) P(x) = 32000*1.04^x
- b) $37435
- c) During year 7
Step-by-step explanation:
<u>Given</u>
- Initial pay = $32000
- Increase rate = 4%
a. <u>Formula</u>
b. Year 5 is after 4 years, so we are looking for the value of P(4)
- P(4) = $32000*1.04^4 = $37435
c. <u>P(x) = 40000, x = ?</u>
- 40000 = 32000*1.04^x
- 1.04^x = 40000/32000
- 1.04^x = 1.25
- log 1.04^x = log 1.25
- x = log 1.25 / log 1.04
- x = 5.69, this is 6 years after
The required number of the years is 6 + 1 = 7
Answer:
Kindly check explanation
Step-by-step explanation:
When we have an exponential function, this means that a certain item of sum changes by a fixed percentage rate over a certain period of time.
Decay in Mathematics means reduction. Hence, Applying this knowledge to the concept of exponential Decay, we could say exponential deacy means a reduction process an object or thin undergoes as it decreases by a fixed percentage rate over a certain period of time.
Mathematically, exponential Decay is expressed as :
y = a(1-b)^x
Where, a = Initial amount
(1 - b) = Decay factor ; where b = decay rate.
x = period.
Answer:
-5 + 25 = 20
Step-by-step explanation:
as long as the positive integer is greater than 10 the sum will be larger than 5
Try this website called wolfram Alpha. It's an easy-to-use but advanced calculator. It gives you lots of information for every query. Here's a direct link to the answer to your question on Wolfram Alpha: http://www.wolframalpha.com/input/?i=h(x)%3D(x%2B2)-1. Hope this helps!
A circle goes 360 degrees so we take the 18 and divide it, so-
360 divided by 18 which gives you 20
So the polygon has 20 sides
Hope this helps :)
