Find the amount necessary to fund the given with drawls. Quarterly withdrawals of $850 for 9 years with an interest rate of 4.4%
Lostsunrise [7]

Answer:

The principal amount necessary to fund is $573.31

Step-by-step explanation:

Given as :

The quarterly withdrawal amount = A = $850

The time period for withdrawals = t = 9 years

The rate of interest = r = 4.4% compounded quarterly

Let The principal amount necessary to fund = $p

Now, <u>From Compound Interest</u>

Amount = Principal × (1+\frac{rate}{100\times 4})^{4\times time}

Or, $850 = p × (1+\frac{r}{100\times 4})^{4\times t}

Or, $850 = p × (1+\frac{4.4}{100\times 4})^{4\times 9}

Or, $850 = p × (1.011)^{36}

Or, $850 = p × 1.4826

∴ p = \frac{850}{1.4826}

i.e p = $573.31

So,The principal amount necessary to fund = p = $573.31  

Hence, The principal amount necessary to fund is $573.31   Answer

Name each polynomial by degree and number of terms -10x
Alenkasestr [34]

Answer:

Polynomials are classified according to their number of terms. 4x3 +3y + 3x2 has three terms, -12zy has 1 term, and 15 - x2 has two terms. As already mentioned, a polynomial with 1 term is a monomial. A polynomial with two terms is a binomial, and a polynomial with three terms is a trinomial

Solve each equation for 0° &lt; x &lt; 360°.
Ipatiy [6.2K]

Answer:

Hence value for x is 0 degree

Step-by-step explanation:

Given:

x limits are (0 to 360) degrees and

Cos(x+45)+cos(x-45)=Sqrt(2)

To Find:

value for X

Solution:

Given equation cos(x+45)+ cos(x-45)

Is similar to cos(A+B) +cos(A-B)=2cosA*cosB

Now comparing with general formula we get ,

A=x and B=45

S

Hence given equation becomes as ,

2cosA*cosB=Sqrt(2)

2Cosx*cos45=Sqrt(2)

cosx=Sqrt(2)/(2*cos45)..........cos45=1/\sqrt{2}

Cosx=Sqrt(2)/Sqrt(2)

cosx=1

x= 0

Hence value for x is 0 degree
