F (x) = -6 x + 1/2 : find the inverse

Scorpion4ik [409]

The inverse of the given function is y = (12-x)/6

<h3>Inverse of a function</h3>

Given the following function expressed as:

f(x) = -6x +1/2

Replace y with x

x = -6y + 1/2

Make y the subject of the formula

6y = -x + 12

y = (12-x)/6

Hence the inverse of the given function is y = (12-x)/6

1. Two thousand dollars is invested at 5.5 percent interest compounded

Dafna11 [192]

Two thousand dollars is invested at 5.5 percent interest compounded

quarterly for 2 years. Then the amount is $ 2230.88

<u>Solution:</u>

Given that Two thousand dollars is invested at 5.5 percent interest compounded quarterly for 2 years

<em><u>The formula for amount using compounded quarterly is given as</u></em>:

$\text { Amount }=P\left(1+\frac{R / 4}{100}\right)^{4 T}$

Where, "p" is the principal sum

"R" is the rate of interest

"T" is the number of years

Here in this problem,

P = 2000 ; R = 5.5 ; T = 2 years

Plugging in values in formula we get,

$\text {Amount}=2000\left(1+\frac{\frac{5.5}{4}}{100}\right)^{4 \times 2}$

$=2000\left(1+\frac{1.375}{100}\right)^{8}$

On solving we get,

$=2000(1+0.01375)^{8}=2000(1.11544)=2230.88$

Hence the amount is $ 2230.88

Which of the following are rational numbers {7,-5,2/3,5.79,,√13,√-4}

Ilia_Sergeevich [38]

Answer:

7, -5, 2/3, 5.79

Step-by-step explanation:

rational numbers are numbers you can put in fraction form. $\sqrt{13}$ is not a perfect square, therefore you cannot put it in fraction form. $\sqrt{-4}$ is an imaginary number. Rational numbers are in the Real Numbers category, so it is not a rational number.
