The question is shown in the picture

Masteriza [31]

20 + 25(times the number of hours) = 282.50
You add the 20 because of the one time service fee.

Now lets work this out.
20 + 25x =282.50
25x = 262.50 (subtract both sides by 2 to get the x's alone)
x = 10.5 (divide both sides by 25 to get just x)
x = 10.5 hours

So the answer is A.

15. Which best reflects a correct conversion of an equation in exponential form to logarithmic form?

kkurt [141]

Answer:

$5^x = 25$

$\log_525 = x$

Step-by-step explanation:

Given

Convert from exponential to logarithm

(a) to (d)

Required

Which of the options is correct

Given that:

$a^b = c$ --- Exponential

The logarithm form is:

$b = \log_ac$

From (a) to (d), only option (c) is correct.

Because it follows the above pattern

i.e.

$5^x = 25$ $\to$ $\to$ $a^b = c$

$a = 5$ $b = x$ $c = 25$

$b = \log_ac$ becomes

$x = \log_525$

$\log_525 = x$

What is the value of x?

satela [25.4K]

Answer:

x = 4

Step-by-step explanation:

By property of intersecting secants outside of circle.

$PC \times PA = PB \times PD \\ 10(2x + 10) = 9(2x + 3 + 9) \\ 20x + 100 = 18x + 108 \\ 20x - 18x = 108 - 100 \\ 2x = 8 \\ x = \frac{8}{2} \\ \huge \red{ \boxed{ x = 4}}$
