Write a compound interest function to model each situation. Then find the balance after the given number of years.

andriy [413]

Answer:

See explanation

Step-by-step explanation:

The standard compound interest formula is $A = P(1+\frac{r}{n})^{nt}$ where:

P is the principal amount

r is the interest rate (typically as a percentage)

t is the time

n is the times compounded per unit of time

So,

1) $A = 50000(1+\frac{0.03}{12})^{(12)(6)} =59847.42$

2) $A = 43000(1+\frac{0.05}{1})^{(1)(3)} =49777.88$

3) $A = 65000(1+\frac{0.06}{4})^{(4)(12)} =132826.08$

You should check my answers though, I may have mixed up some terms.

I dont understand this

Westkost [7]

Answer:

$\dfrac{1}{2x(x-1)}$

Step-by-step explanation:

Given

$\dfrac{x^2+2x+1}{x^2-1}\div (2x^2+2x)$

Consider the numerator:

$x^2+2x+1=(x+1)^2$

Consider the denominator:

$x^2-1=(x-1)(x+1)$

Hence, the fraction becomes

$\dfrac{(x+1)^2}{(x-1)(x+1)}=\dfrac{x+1}{x-1}$

Consider the expression in brackets:

$2x^2+2x=2x(x+1)$

Divide:

$\dfrac{x^2+2x+1}{x^2-1}\div (2x^2+2x)=\dfrac{x+1}{x-1}\div 2x(x+1)=\dfrac{x+1}{x-1}\times \dfrac{1}{2x(x+1)}=\dfrac{1}{2x(x-1)}$

What is the true solution to 2 in e^in 5x = 2 in 15

Mkey [24]

We have to solve this equation:
$2 * ln e ^{ln(5x)}= 2 * ln 15/:2 \\ ln e ^{ln(5x)}=ln 15 \\ e ^{ln(5x)}=15 \\$
5 x = 15
x = 15 : 5
Answer:
x = 3

Walter and his mother drove to Miami Florida. It took them 9 hours and 45 minutes to drive 658.125 miles. Their average speed wa

OverLord2011 [107]

Answer: 67.5 mph

Step-by-step explanation:

The formula for speed is:

= Distance / Time

Distance = 658.125 miles

Time will need to be converted to a decimal. You may convert only the minutes into hours as the hours are already hours.

= 45/60 minutes

= 0.75 hrs

= 9 + 0.75

= 9.75 hours

Speed = 658.125 / 9.75

= 67.5 mph
