Answer:
The approximate growth rate of the savings account is 2.5%
Step-by-step explanation:
Given the the function S(x) = 5, 000 * (1.025) ^ (0.7x)
From the function, we can see that part: (1.025). It presents for the growth factor or rate with the formula as:
(1 + r) where r is rate
So we have:
(1 + r) = 1.025
<=> r = 1.025 -1
<=> r = 0.025
In pecentage, we have the rare: 0.025 *100% = 2.5%
So the approximate growth rate of the savings account is 2.5%
Set up a system of equations.
d + q = 75
.1d + .25q = 14.25
Multiply the first equation by -.1 so that the "d's" will cancel.
-.1d -.1q = -7.5
.1d +.25q = 14.25
Now add the two equations together
.15q = 6.75
divide both sides by .15
q = 45
There are 45 quarters in the jar
Answer:
15 is your number and is a factor of 5 between 10 and 10
Lets say the number is x so we can make an equation
If is at least 21, that means it has to be greater then or equal to it.
6+5*x>=21
You can subtract 6 from both sides
5*x>=15
Then divide both sides by 5
x>=3
You can conclude that the number is greater then or equal to 3.
