**Answer:**

See Below

**Step-by-step explanation:**

**<em>The equation of f(x) isn't given so I will assume one equation for f(x) and solve the problem to show the process. The answer choices won't hold.</em>**

**<em />**

**<em>New Problem:</em>**

**<em>Find (g ∘ f)(10) when f(x) = 3x - 1 and g(x) = 2x + 3</em>**

**<em />**

<u>Solution:</u>

The notation **<em>(g ∘ f)(10) </em>**means take the function "f" and put it into "g" and then evaluate that expression with "10". First, lets find **<em>(g ∘ f)(x).</em>**

**<em />**

f(x) = 3x - 1

g(x) = 2x + 3

(g ∘ f)(x) = 2(3x - 1) + 3

= 6x - 2 + 3

= 6x + 1

So,

(g ∘ f)(x) = 6x + 1

Now,

(g ∘ f)(10) = 6(10) + 1 = <u>**61**</u>

<u>**This would be the answer.**</u>

<h3>The amount of Chlorine (A) to add to a basin is 112590000000</h3>

<em><u>**Solution:**</u></em>

Given that,

<em><u>**A wastewater treatment operator uses the formula:**</u></em>

Where,

A = amount of chlorine to add to basin

The flow through the basin is Fand the concentration of Chlorine to water is C

From given,

F = 1800

C = 7, 500, 000

To find: A

Thus amount of Chlorine (A) to add to a basin is 112590000000

**Answer:**

**Step-by-step explanation:**

1 hour = 60 minutes

1 kilometers = 1000m

9 kilometers = 9*1000 = 9000 m

Distance traveled in 60 minutes = 9000 m

Distance traveled in 1 minute = 9000/60

Distance traveled in 30 minutes

= 4500m = 4.5 km

**Answer:**

incorrect

**Step-by-step explanation:**

this is because it would be 1/2 and 1/6. you would have to multiply the bases for a probability of 1/12
