Find the amount financed and the finance charge in dollars for the following problem. Choose the correct answers.
diamong [38]

$350 * 30/100 = $ 105 which is down payment.

$350 - $105 = $245 which is left.

One brand of vinegar has a pH of 4.5. Another brand has a pH of 5.0. The equation for the pH of a substance is pH = –log[H+], wh
kiruha [24]

Answer:

2.16 * (10^-5).

Step-by-step explanation:

5 = -log H+

5 = log (1 / H+)

1/ H+ = 10^5

H+ = 10^-5

In a similar fashion  the other brand has H+ of 10^-4.5.

So the difference in hydrogen ion concentration =  10^(-4.5) - 10^(-5)

= 2.16 * (10^-5).

What is the slope of this line?<br><br> A. -1/2<br> B. 1/2<br> C. -2<br> D. 2
SVEN [57.7K]

We can find the slope of this line by using the slope formula:

\frac{y.2 - y.1}{x.2 - x.1} = m

We'll use the points (-6, 0) and (0, -3)

(-3 - 0) / (0 + 6) = -3/6 = -0.5

The slope of the line is A, -1/2
