Which of the following shows the true solution to the logarithmic equation 3 log Subscript 2 Baseline (2 x) = 3

VARVARA [1.3K]

Answer:

x = 1

Step-by-step explanation:

We have to solve the given logarithmic equation of variable x.

The equation is $3\log _{2} (2x) = 3$

⇒ $\log_{2} (2x)^{3} = 3$

{Since, we know the logarithmic property, $a \log b = \log b^{a}$ }

⇒ $\log_{2} (2x)^{3} = 3\log_{2}2 = \log_{2} 2^{3}$

{Since we know that $\log_{a} a = 1$ }

Now cancelling log from both sides we get,

$(2x)^{3} = 2^{3}$

⇒ $x^{3} = 1$

⇒ x = 1 (Answer)

In 1971, there were 294,105 females participating in high school sports. Since then, that number has increased an average of 8.5

Hitman42 [59]

Answer:

First, we have to calculate how many years passed: 2015 - 1971 = 44 years.

So n = 44 and 8,5% = 0,085 so r = 1 + 0.085 = 1.085.

The starting population is 294,105 and the formula is:

y = 294,105 * r^n = 294,105 * 1.085^44 =

= 294,105 * 36.21666 = 10,651,502.85 ≈ 10,651,503

Answer: In 2015 there were 10,651,503 females participating in high school sports.
