Answer:
132.56
Step-by-step explanation:
to start with $300, and then save $100 each month. Sally has $6000 and decides
to put her money in the bank in an account that has a 7% interest rate that is
compounded annually. Natalie has $5000 and decides to put her money in the
bank in an account that has a 10% interest rate that is compounded continuously.
How much money have after 2 years?
How much money will sally have in 10 years?
What type of exponential model is Natalie’s situation?
Write the model equation for Natalie’s situation
How much money will Natalie have after 2 years?
How much money will Natalie have after 10 years
Answer:
Part 1) John’s situation is modeled by a linear equation (see the explanation)
Part 2)
Part 3)
Part 4)
Part 5) Is a exponential growth function
Part 6)
Part 7)
Part 8)
Part 9) Is a exponential growth function
Part 10) or
Part 11)
Part 12)
Part 13) Natalie has the most money after 10 years
Part 14) Sally has the most money after 2 years
Step-by-step explanation:
Part 1) What type of equation models John’s situation?
Let
y ----> the total money saved in a jar
x ---> the time in months
The linear equation in slope intercept form
y=mx+b
The slope is equal to
The y-intercept or initial value is
so
therefore
John’s situation is modeled by a linear equation
Part 2) Write the model equation for John’s situation
see part 1)
Part 3) How much money will John have after 10 years?
Remember that
1 year is equal to 12 months
so
For x=120 months
substitute in the linear equation
Part 4) How much money will John have after 2 years?
Remember that
1 year is equal to 12 months
so
For x=24 months
substitute in the linear equation
Part 5) What type of exponential model is Sally’s situation?
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above
therefore
Is a exponential growth function
Part 6) Write the model equation for Sally’s situation
see the Part 5)
Part 7) How much money will Sally have after 10 years?
For t=10 years
substitute the value of t in the exponential growth function
Part 8) How much money will Sally have after 2 years?
For t=2 years
substitute the value of t in the exponential growth function
Part 9) What type of exponential model is Natalie’s situation?
we know that
The formula to calculate continuously compounded interest is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
e is the mathematical constant number
we have
substitute in the formula above
Applying property of exponents
therefore
Is a exponential growth function
Part 10) Write the model equation for Natalie’s situation
or
see Part 9)
Part 11) How much money will Natalie have after 10 years?
For t=10 years
substitute
Part 12) How much money will Natalie have after 2 years?
For t=2 years
substitute
Part 13) Who will have the most money after 10 years?
Compare the final investment after 10 years of John, Sally, and Natalie
Natalie has the most money after 10 years
Part 14) Who will have the most money after 2 years?
Compare the final investment after 2 years of John, Sally, and Natalie
Sally has the most money after 2 years
9.000 is the answer so 9 because 9.173 is part of a number or a unit.
The mixed number equivalent of 18/5 is 3 3/5.
To convert the fraction 18/5 into a mixed number, you can divide the numerator 18 by the denominator 5.
The quotient will become the whole number part of the mixed number, and the remainder will become the numerator of the fraction part. Here's the process:
18/5 = 3 3/5
The remainder becomes the numerator of the fraction part, which is 3.
The denominator of the fraction part remains the same, which is 5.
Therefore, the mixed number equivalent of 18/5 is 3 3/5.

Answer:
(k4+3+3k3)+(-5k3+6k3+8k5)
Final result :
8k5 + k4 + 4k3 + 3
Step by step solution :
Step 1 :

Step 2 :
Equation at the end of step 2 :
(((k4)+3)+(3•(k3)))+(((0-(5•(k3)))+(2•3k3))+23k5)
Step 3 :
Equation at the end of step 3 :
(((k4)+3)+(3•(k3)))+(((0-5k3)+(2•3k3))+23k5)
Step 4 :
Equation at the end of step 4 :
(((k4) + 3) + 3k3) + (8k5 + k3)
Step 5 :
Checking for a perfect cube :
5.1 8k5+k4+4k3+3 is not a perfect cube
Trying to factor by pulling out :
5.2 Factoring: 8k5+k4+4k3+3
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: k4+3
Group 2: 8k5+4k3
Pull out from each group separately :
Group 1: (k4+3) • (1)
Group 2: (2k2+1) • (4k3)
Bad news !! Factoring by pulling out fails :
The groups have no common factor and can not be added up to form a multiplication.
Polynomial Roots Calculator :
5.3 Find roots (zeroes) of : F(k) = 8k5+k4+4k3+3
Polynomial Roots Calculator is a set of methods aimed at finding values of k for which F(k)=0
Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers k which can be expressed as the quotient of two integers
The Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading Coefficient
In this case, the Leading Coefficient is 8 and the Trailing Constant is 3.
The factor(s) are:
of the Leading Coefficient : 1,2 ,4 ,8
of the Trailing Constant : 1 ,3
