Answer:

B.

Step-by-step explanation:

2,400 = 7,500(10)^{x}

First of all, you want to isolate the (10)^{x} by dividing each side by 7,500.

After doing this, you will get

\frac{2400}{7500} = (10)^{-x}.

Putting this in the logarithmic form, you get log_{10} \frac{2400}{7500} = - x

To get rid of the negative sign, you would simply multiply both dies of the equation by -1. So you would get  -log_{10}  \frac{2400}{7500} = x.

When you simplify 2400/7500, you get 8/25, so the answer is B.

Hope this helps!

What is the arc length?
Gwar [14]

Answer:

approximately 21, when rounded to nearest tenth.

Step-by-step explanation:

First, let's find the measure of angle BAD. Angles BAD and DAC add up to 180 degrees, so 180-57= 123 degrees. Now, let's find the circumference of the circle. The circumference is diameter * π, which is 19.6(π). Then, the ratio is 123/360, so multiply 19.6(π) by 123/360, and you get 21.0381988...... which simplifies to 21 (rounded to nearest tenth)
