Brenda invests $4,848 in a savings account with a fixed annual interest rate of 5% compounded 2 times per year. What will the ac

s2008m [1.1K]

She invests some amount in a saving account of fixed interest compounded half-yearly. It says to find its Future Value after six years.

The principal amount is P = $4,848.

Annual interest rate is 5% i.e. r = 0.05

Compounding period is two times per year i.e. n = 2.

Time of investment is t = 6 years.

We know the formula of Future Value is given by :-

$FV=P*(1+\frac{r}{n})^{nt}$

We can plug the given values in the formula to calculate the answer.

$FV = 4848*(1+\frac{0.05}{2})^{(2*6)} \\\\ FV = 4848*(1+0.025)^{(12)} \\\\ FV = 4848*(1.025)^{(12)} \\\\ FV = 4848*(1.344888) \\\\ FV = 6520.02102$

Hence, future value of investment after six years is 6,520.02 dollars.

Question:

prohojiy [21]

Answer:

x = 3/2 + sqrt(17)/2 or x = 3/2 - sqrt(17)/2

Step-by-step explanation:

Solve for x over the real numbers:

x/x - 1 = x - 3 - 2/x

x/x - 1 = 0:

0 = x - 3 - 2/x

0 = x - 3 - 2/x is equivalent to x - 3 - 2/x = 0:

x - 3 - 2/x = 0

Bring x - 3 - 2/x together using the common denominator x:

(x^2 - 3 x - 2)/x = 0

Multiply both sides by x:

x^2 - 3 x - 2 = 0

Add 2 to both sides:

x^2 - 3 x = 2

Add 9/4 to both sides:

x^2 - 3 x + 9/4 = 17/4

Write the left hand side as a square:

(x - 3/2)^2 = 17/4

Take the square root of both sides:

x - 3/2 = sqrt(17)/2 or x - 3/2 = -sqrt(17)/2

Add 3/2 to both sides:

x = 3/2 + sqrt(17)/2 or x - 3/2 = -sqrt(17)/2

Add 3/2 to both sides:

Answer: x = 3/2 + sqrt(17)/2 or x = 3/2 - sqrt(17)/2

In an asteroid field, 75% of the asteroids are carbonaceous asteroids. There are 375,000 carbonaceous asteroids in the asteroid

Olenka [21]

Given:

In an asteroid field, 75% of the asteroids are carbonaceous asteroids.

There are 375,000 carbonaceous asteroids in the asteroid field.

To find:

The number of asteroids that are not carbonaceous.

Solution:

Let the total number of asteroids be x.

According to question,

$75\%\text{ of }x = 375000$

$\dfrac{75}{100}x=375000$

$0.75x=375000$

Divide both sides by 0.75.

$x=\dfrac{375000}{0.75}$

$x=500000$

Asteroids not carbonaceous = Total asteroids - Carbonaceous asteroids

$=500000-375000$

$=125000$

Therefore, 125,000 asteroids are not carbonaceous.
