How to solve log base 5 of x + log base 5 of (4x-1)

1 answer:

7 0

Log5(x)+log5(4x-1)
As the bases are the same the number doesn't matter
Log (a) + log(b) =log (ab)

Log(4x^2-x)

(x )(4x-1)

x=0.25 or x=0

Log(4×0.25^2-0.25) = log(0) = Infinity
Same with 0. So no answer

Find the area between the graph of the function and the x-axis over the given interval, if possible.

vodomira [7]

Answer:

$A= -\frac{5}{-1} - \lim_{x\to\infty} \frac{5}{x-2} = 5-0 = 5$

So then the integral converges and the area below the curve and the x axis would be 5.

Step-by-step explanation:

In order to calculate the area between the function and the x axis we need to solve the following integral:

$A = \int_{-\infty}^1 \frac{5}{(x-2)^2}$

For this case we can use the following substitution $u = x-2$ and we have $dx = du$

$A = \int_{a}^b \frac{5}{u^2} du = 5\int_{a}^b u^{-2}du$

And if we solve the integral we got:

$A= -\frac{5}{u} \Big|_a^b$

And we can rewrite the expression again in terms of x and we got:

$A = -\frac{5}{x-2} \Big|_{-\infty}^1$

And we can solve this using the fundamental theorem of calculus like this:

$A= -\frac{5}{-1} - \lim_{x\to\infty} \frac{5}{x-2} = 5-0 = 5$

So then the integral converges and the area below the curve and the x axis would be 5.

Answer:

x=19(rounded) or 18.7882942281

Step-by-step explanation:

a^2+b^2=C^2

8^2+17^2=C^2

64+289= C^2

353=C^2

$\sqrt{353} =\sqrt{C^2}\\$

18.7882942281= C

19= C
