Answer:

154

Step-by-step explanation:

The formula for the area is A=πr2

The line labeled 7 is the radium or the R in the formula

Replace 7 with R

A=π7(squared)

square seven

A=49π

pi is approximately 3.14

mutiply 7 by pi

A= 154

Answer:

Option C. (-x,y)

Step-by-step explanation:

we know that

A point reflected across the y-axis has the following rule

(a,b)------> (-a,b)

If the center of the original circle was located at (x, y)

then

the center of the new circle after the transformation will be (-x,y)

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

Finger [1]

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 !:)

Write a expression for 18.68+11.72+19.76+18.68

Ilia_Sergeevich [38]

ANSWER:

The simplified form of the given expression 18.68+11.72+19.76+18.68 after applying BODMAS rule is 4684.

SOLUTION:

The expression given to us is 18.68+11.72+19.76+18.68. We are to simplify the equation.

To simplify the equation we have to follow the BODMAS rule.

Which sets different mathematical operations at different levels of priority.

BODMAS mean brackets, of, division, multiplication, addition and subtraction.

To solve different mathematical equations we have to follow this order of priority to get the correct answer.

Now applying BODMAS rule to the given expression we have to solve it to get an answer.

18.68+11.72+19.76+18.68

As the rule states we have to do multiplication before addition. Therefore,

1224+792+1444+1224

Now pursuing the equation for addition we get

2016+2668=4684

Hence the simplified form of the given expression after applying BODMAS rule is 4684.

What is the answer? With explanation please!

irina [24]

B. Step 2 should’ve brought the negative sign down with the 72.
You can see that the equation went from -72 = 4x -30 to
72 = 4x - 30
