Answer:
Step-by-step explanation:
If the degree of the polynomial is even (positive) ends of the function will either upwards or downwards on axis.
If the coefficient of the leading term of a polynomial is negative, both the ends of the graph will move downwards.
The given function is,
f(x) = -x⁴ + 9
Degree of the polynomial = 4
Coefficient of the leading term = -1
Therefore, ends of the polynomial will open downwards.
Answer:
Option d)$401,447.24
Step-by-step explanation:
We are given that as part of your retirement plan, you want to set up an annuity in which a regular payment of $35,000 is made at the end of each year at rate of 6% compounded annually for 20 years
So first of all we need to find the future value of annuity using the formula as shown below :
Here, FV = future value of annuity
p = $35000 (annual deposit)
r is rate = 6% = 0.06
n = number of compounding = 1 ( as we are compounding annually )
t = number of years = 20
So plugging in all the values in the formula , we get
Simplifying further , we get
Plugging in the given values in the calculator , we get
FV = $ 1287495.69
So far we have got the Total amount for annuity , from here we need to use the concept of compound interest and find the principal amount to be deposited to get the required total amount of $ 1287495.69
The formula for compound interest when compounded annually is given by:
Here A = 1287495.69 (Total amount required)
P = ( principal amount to be deposited to meet the required total amount )
r = 6% = 0.06
t = 20
So plugging in all the known values in the formula , we get
simplifying further, we get
so required amount to be deposited is given by :
P = $401,447.24
