Remember to follow PEMDAS. First, divide
450/45 = 10
Finally, add
10 + 5 = 15
15 is your answer
hope this helps
Answer:
The yearly rate of appreciation of the comic book is r=0.017 or r=1.7%
Step-by-step explanation:
we have
This is a exponential function of the form
where
a is the initial value
b is the base
In this problem
a=$1,350
b=1.017
Remember that
b=1+r
so
1+r=1.017
r=1.017-1=0.017
therefore
The yearly rate of appreciation of the comic book is r=0.017 or r=1.7%
Step-by-step explanation:
let the unknown members be X
At first, the club had 20 + X members
After the first year,
2( 20+X)
The second year,
2( 20 +X/2) +40
The third year,
3[2(20+ X/2) +40]
Total number =
20+X + 2(20+X) + 2( 20 +X/2) +40 +3[2(20+ X/2) +40]
= 20+ X + 40+ 2X + 40 +2X/2 +40 +3[40+2X/2 +40]
= 20+40+X +2X +40+X+ 40 + 3[ 40+40+X]
= 60 +3X +80+X + 3[80+X]
= 140+4X + 240+3X
=380 + 7X
-380=7X
X = -54.3
A baseball would weigh 140 grams because each nickel weigh 5 grams and 28x5=140
Answer:
dP/dt = k*(600 - P)*P
Step-by-step explanation:
Given:
- Total number of people in company N = 6000
- Total people involved in bribery P
The rate at which people become involved in a corporate bribing scheme is jointly proportional to the number of people already involved and the number of people who are not yet involved.
Find:
Write a differential equation
Solution:
- The following differential equation can be used to describe the situation above:
Number of people not affected = N - P
- Hence we can write a differential equation:
dP/ dt = k *( N - P )*P
- input the value of N:
dP/dt = k*(600 - P)*P
