Are the following two matrices inverses of one

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>

<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
