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 :

FV= p\frac{[(1+\frac{r}{n})^{(n)(t)}-1)]}{\frac{r}{n}}

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

FV= 35000\frac{[(1+\frac{0.06}{1})^{(1)(20)}-1)]}{\frac{0.06}{1}}

Simplifying further , we get

FV= 35000\frac{[(1+0.06)^{20}-1)]}{0.06}

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:

A=P(1+r)^t

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

1287495.69= P(1+0.06)^{20}

simplifying further, we get

\frac{1287495.69}{(1.06)^{20}}= P

so required amount to be deposited is given by :

P = $401,447.24

Hope it was helpful !:)

2. One angle is one less than six times the measure of
Illusion [34]

The equations used to find the measure of each angle in degrees is x + y = 90 and x = 6y - 1

The two complementary angles are 77 degrees and 13 degrees

<em><u>Solution:</u></em>

Given that two angles are complementary angles

Complementary angles are two angles whose sum is 90 degrees

Let one of the angle be "x" and the other angle be "y"

Therefore,

x + y = 90 ------ eqn 1

Also given that,

One angle is one less than six times the measure of  another

one angle = six times the other angle - 1

x = 6y - 1 ------ eqn 2

Substitute eqn 2 in eqn 1

6y - 1 + y = 90

Thus the above equation is used to find the measure of each angle in degrees

Solve the above equation

6y + y - 1 = 90

7y - 1 = 90

7y = 91

y = 13

Substitute y = 13 in eqn 2

x = 6(13) - 1

x = 78 - 1

x = 77

Thus the two complementary angles are 77 degrees and 13 degrees

gtnhenbr [62]

Answer:

height = 12 cm

Step-by-step explanation:

Parallelogram 1:

Area =  base *height = 20 * 15 = 300 sq. cm

Area of parallelogram 2 = area of parallelogram 1

25 * height = 300

       height = 300/25

height = 12 cm
