Darlene Fine wants to have at least $50,000 in her savings account in 10 years. If her account pays 3.6% interest compounded ann

marshall27 [118]

In this problem the question asked is what principal should be invested on a rate of interest of 3.6% for 10 years to get the totals amount as 50000$
the formula for compound interest is
A=P*(1+R/100)^T
we shall replace the formula
50000=X*(1+3.6/100)^10
50000=x*(100/100+3.6/100)^10
50000=x*(103.6/100)^10
50000=X*(1.036)^10
50000=1.4242x
50000/1.4242=X
35107.42=X
hope u found this useful
feel free to check

Write the function a a product of linear factor by grouping or using the x method or a combination of both

Sladkaya [172]

<h3>Answer:</h3>

$\boxed{\boxed{\pink{\sf Option \ A \ is \ correct .}}}$

<h3>Step-by-step explanation:</h3>

Given function to us is :-

$\bf \implies g(x) = x^2 - 9$

And we , need to write the function a a product of linear factor by grouping or using the x method or a combination of both . So let's factorise this ,

$\bf \implies g(x) = x^2 - 9 \\\\\bf\implies g(x) = x^2-3^2\\\\\bf\implies \boxed{\red{\bf g(x) = (x+3)(x-3) }}\:\:\bigg\lgroup \blue{\tt Using \ (a+b)(a-b) \ = a^2-b^2 }\bigg\rgroup$

I have also attached the graph of x²-9.

<h3>Hence option A is correct .</h3>

A man divided $9,000 among his wife, son, and daughter. The wife received twice as much as the daughter, and the son received $1

monitta

Answer:

Q1:

Share of the daughter (x):

2x + x + x + $1,000 = $9,000

4x = $8,000

x = $2,000

Share of the wife:

= 2($2,000)

= $4,000

Share of the son:

= $2,000 + $1,000

= $3,000

Answer: wife, $4,000; son, $3,000; daughter, $2,000

Q2:

= 1/2x + $1,000

Answer: 1/2x + $1,000: expression for share of the son

Proof (the wife shares $4,000):

Share of wife (x):

x + 1/2x + 1/2x + $1,000 = $9,000

2x = $8,000

x = $4,000

Step-by-step explanation:

hope it helps!

How much must you deposit in an account that pays 6.25% interest, compounded annually, to have a balance of $700 after two years

Amanda [17]

The compound interest is applied to the remaining balance in the account

each subsequent year.

The amount that must be deposited is approximately $620.07

Reasons:

The given compound interest rate, r = 6.25% = 0.0625

The balance in the account after 2 years, A = $700

Required:

The required deposit, P, that gives the given account balance after 2 years.

Solution:

The following is the compound interest formula to use;

$A = \mathbf{P \times \left(1+r \right)^{ t}}$

Where;

t = 2 years

We get;

$\displaystyle P = \mathbf{ \frac{A}{(1 + r)^t}}$

Which gives;

$\displaystyle P = \frac{700}{(1 + 0.0625)^2} \approx \mathbf{620.07}$

The amount that must be deposited to give $700 after 2 years is P ≈ $620.07
