HELP PLEASE!! I DONT UNDERSTAND!!!!!!!!!! THANKS SO MUCH

8090 [49]

Hello, please consider the following.

We will multiply the numerator and denominator by

$4+\sqrt{6x}$

to get rid of the root in the denominator.

First of all, we cannot divide by 0, right? So, we need to make sure that the denominator is different from 0.

$4-\sqrt{6x} =0\sqrt{6x}=4\\\\\text{Take the square}\\\\6x=4^2=16\\\\x=\dfrac{16}{6}=\dfrac{8}{3}$

We need to take any x real number different from 8/3 then and simplify the expression.

Let's do it!

$\begin{aligned}\dfrac{4}{4-\sqrt{6x}}&=\dfrac{4(4+\sqrt{6x})}{(4+\sqrt{6x})(4-\sqrt{6x})}\\\\&=\dfrac{4(4+\sqrt{6x})}{(4^2-\sqrt{6x}^2)}\\\\&=\dfrac{4(4+\sqrt{6x})}{(16-6x)}\\\\&=\dfrac{2(4+\sqrt{6x})}{(8-3x)}\\\\&\large \boxed{=\dfrac{8+2\sqrt{6x}}{8-3x}}\end{aligned}$

Thank you

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.

the telephone company purchased 95 yards of wire for $1235 in september. they plan on making a purchase of 285 yards in October.

Luden [163]

Ratio and propoertion

cost/amount is constant
1235/95=x/285
cross multiply or time both sides by (95 times 283)
351975=95x
divide oth sies by 95
3705=x

the cost is $3705
