For the first one, the line will touch the y axis at 2 and the slope is positive because it goes upward. This means that A and B are wrong. I'd say the slope is about 2 so the answer is C) y = 2x + 2

For the second one, the line touches the y axis at 6 and the slope is negative because it's going downward. I'd say the slope is -1 so the answer to this one is D) y = -x + 6

Hope that helps!

A container of orange juice has a pH of 3.3. Find the concentration of hydronium ions in the milk.

kap26 [50]

The concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if the container of orange juice has a pH of 3.3.

<h3>What is pH value?</h3>

The pH of a solution is a measurement of the concentration of hydrogen ions in the solution, as well as its acidity or alkalinity. Normally, the pH scale ranges from 0 to 14.

We have:

A container of orange juice has a pH of 3.3.

The pH value = 3.3

$\rm pH = -log[H_3O^+]$

$\rm 3.3 = -log[H_3O^+]$

Removing log:

$\rm 10^{-3.3}=[H_3O^+]$

$\rm [H_3O^+] = 5.011\times10^{-4}$

Thus, the concentration of the hydronium ions in the milk is 5.011×10⁻⁴ if the container of orange juice has a pH of 3.3.

Answer:

1. The interest is $ 117.

2. The amount is $ 1,317.

Step-by-step explanation:

The following data were obtained from the question:

Principal (P) = $ 1,200

Rate (R) = 3.25%

Time (T) = 3 years

Interest (I) =..?

Amount (A) =...?

1. Determination of the interest.

Principal (P) = $ 1,200

Rate (R) = 3.25%

Time (T) = 3 years

Interest (I) =..?

I = P × R × T / 100

I = 1200 × 3.25 × 3 / 100

I = $ 117

Therefore, the interest is = $ 117

2. Determination of the amount.

This can be obtained as follow:

Interest (I) = $ 117

Principal (P) = $ 1,200

Amount (A) =?

Amount (A) = principal (P) + interest (I)

A = P + I

A = 1200 + 117

A = $ 1,317

Therefore, the amount at the end of 3 years is $ 1,317
