Answer:

x = 2.564 ( to 3 dec. places )

Step-by-step explanation:

Using the rule of logarithms

log $x^{n}$ ⇔ n logx

Given

$5^{x}$ = 62 ( take the ln of both sides )

ln $5^{x}$ = ln 62, that is

x ln5 = ln 62 ( divide both sides by ln 5 )

x = $\frac{ln62}{ln5}$ ≈ 2.564

Your company gives you a cell phone plan which allows you 600 minutes to talk per month. So far this month, you have used 330 mi

Evgen [1.6K]

The answer is C) 10x + 330 ≤ 600.
We use the ≤ since you are allowed to use the 600th minute.
When we subtract 330 from both sides, it makes a bit more sense
10x ≤ 270
270 is the number of minutes left your plan since you've already used 330, and you have 10 days left in the month.

Answer:

f'(1) = 2

Step-by-step explanation:

f(x) = 2x^2 -2x +3

Take the derivative

f'(x) = 2 * 2x - 2 * 1

f'(x) = 4x -2

f'(1) = 4(1) -2

=4-2
