Condene the logarithms on the left side by applying the property, ln(a) - ln(b) = ln(a / b):

ln(x - 2) - ln(x - 3) = 1

→ ln((x - 2) / (x - 3)) = 1

Now take the exponential of both sides:

exp(ln((x - 2) / (x - 3))) = exp(1)

(x - 2) / (x - 3) = e

Solve for x :

x - 2 = e (x - 3)

x - 2 = e x - 3e

x - e x = 2 - 3e

(1 - e) x = 2 - 3e

x = (2 - 3e) / (1 - e) ≈ 3.582

What is the circumference of the circle if r = 3.5 feet? Use 22 7 for π.45 pts

Natasha_Volkova [10]

We know, Circumference of a Circle = 2πr
C = 2 * 22/7 * 3.5
C = 2 * 22/2
C = 2 * 11
C= 22

In short, Your Answer would be 22 Feet

Which shows the expressions rewritten with the least common denominator?

baherus [9]

Answer:

D. (14x-4)/(8x^2) and (x^2-x)/(8x^2)

Step-by-step explanation:

The least common denominator will be 8x^2, the product of 2 and x to the highest of their powers in either of the denominators.

$\left\{\dfrac{7x-2}{4x^2},\ \dfrac{x-1}{8x}\right\}=\left\{\dfrac{7x-2}{4x^2}\cdot\dfrac{2}{2},\ \dfrac{x-1}{8x}\cdot\dfrac{x}{x}\right\}\\\\=\left\{\dfrac{14x-4}{8x^2},\ \dfrac{x^2-x}{8x^2}\right\}$
