Answer:
The amount of money in the account after t years is given by:
Step-by-step explanation:
Compound interest:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Invested $5000 at 6% per year and is compounded quarterly
This means, respectively, that
So, the amount of money in the account after t years will be given by:
Answer:
Part 1) The greater unit rate of the two functions is the linear function of the table
Part 2) The greater y intercept of the two functions is the linear equation of the graph
Step-by-step explanation:
we know that
The rate of a linear function is equal to the slope
step 1
Find the slope of the linear equation in the table
we have
(0,5) and (5,15)
The slope is equal to
To find the unit rate divide by 5 both numerator and denominator
step 2
Find the slope of the linear equation of the graph
we have
(-4,0) and (0,6)
The slope is equal to
To find the unit rate divide by 2 both numerator and denominator
Compare the unit rate of the two linear equations
2 > 1.5
therefore
The greater unit rate of the two functions is the linear function of the table
step 3
Find the y-intercepts of the linear equations
Remember that the y-intercept is the value of y when the value of x is equal to zero
<em>Linear equation of the table</em>
Observing the table
For x=0, y=5
therefore
The y-intercept of the linear equation of the table is the point (0,5)
<em>Linear equation of the graph</em>
Observing the graph
For x=0, y=6
therefore
The y-intercept of the linear equation of the table is the point (0,6)
Compare the y-intercept both functions
6 > 5
therefore
The greater y intercept of the two functions is the linear equation of the graph
