The denominator of a fraction in the simplest form is greater than the numerator by 1. If 4 is added to the numerator, and 3 is

Fantom [35]

Answer:

Step-by-step explanation:

Let the original fraction is: x/ x-1

And we have that:

4 is added to the numerator => new numerator is: x+4
3 is subtracted from the denominator => new denominator is: x -1-3 = x -4

the fraction itself is increased by 2 $\frac{1}{6}$

<=> $\frac{x}{x-1} *2\frac{1}{6}$ = $\frac{x+4}{x-4}$

<=> $7x^{2} -70x +24 = 0$

Solve for X then we substitue into the original fraction

S (SOA) An annuity pays 1 at then end of each year for n years. Using an annual effective interest rate of i, the accumulated va

Reptile [31]

Answer:

Step-by-step explanation:

Given:

Annuity at time (n + 1) = 13.776

(1 + i)ⁿ = 2.476

Now,

$S_{n/i}=\frac{(1+i)^n-1}{d}$

here, d = $\frac{i}{1-i}$

thus,

$13.776=\frac{2.476-1}{d}$

d = 0.1071

therefore,

d = $\frac{i}{1+i}$

0.1071 = $\frac{i}{1+i}$

0.1071 + 0.1071i = i

i = 0.1199

now,

(1 + i)ⁿ = 2.476

(1 + 0.1199)ⁿ = 2.476

1.1199ⁿ = 2.476

taking log both sides

n × log(1.1199) = log(2.476)

n = 8.006 ≈ 8

hence,

the answer is 8

Answer: $\frac{8}{3}\times \sqrt{\frac{2}{5}}$

Step-by-step explanation:

Given two upward facing parabolas with equations

$y=6x^2 & y=x^2+2$

The two intersect at

$6x^2=x^2+2$

$5x^2=2$

$x^2$ = $\frac{2}{5}$

x= $\pm \sqrt{\frac{2}{5}}$

area enclosed by them is given by

A= $\int_{-\sqrt{\frac{2}{5}}}^{\sqrt{\frac{2}{5}}}\left [ \left ( x^2+2\right )-\left ( 6x^2\right ) \right ]dx$

A= $\int_{\sqrt{-\frac{2}{5}}}^{\sqrt{\frac{2}{5}}}\left ( 2-5x^2\right )dx$

A= $4\left [ \sqrt{\frac{2}{5}} \right ]-\frac{5}{3}\left [ \left ( \frac{2}{5}\right )^\frac{3}{2}-\left ( -\frac{2}{5}\right )^\frac{3}{2} \right ]$

A= $\frac{8}{3}\times \sqrt{\frac{2}{5}}$
