Okay, so all this question wants you to do is plug in 2 for x and solve for your output, aka y.

y = -4x² - 8

when x = 2....
y = -4(2)² - 8

y = -16 - 8
y = -24

so, when your input is 2, your output is -24.

The answers to the question are:

  • 50
  • 75
  • 10
  • 14

<h3>a. How to determine the service charge rate for the month of October</h3>

This is the number of calls for the help desk

160000/3200 = 50per call

network center

735000/9800

= 75 per device that was monitored

Electronic mail

100000/10000 =

10 for the mail account

For smart phone support

124600/8900

= 14 per phone extension

<h3>b. Charges to the COMM sector </h3>

for helpdesk

5200 * 0.25 * 0.96 *1.5 calls * $50

= 93600

For network center

(5200 * 0.25 * 0.96) + 600] x 75

= 138600

For Electronic mail

5200 * 0.25 * 0.96 * 10 per email account

= 12480

Smart support charge

5200 * 0.25 * 14 = 18200

What is f(3)??????????
AURORKA [14]
<h3><u>Explanation</u></h3>
  • Meaning of f(a)

f(a) means the value of f(x) is ... when x = a. That means if we substitute x = 3, we would get f(3).

f(3) also means the value of f(x) is ... when x = 3.

f(x) can also be defined as y // f(x) = y

  • Find f(3) by graph.

You can find the value of f(x) at specific domain from the graph by looking at x = 3 then look up to where the point or where the graph passes. From the graph, when x = 3 as we look up and the graph passes y-coordinate at 1.

Therefore we can say that when x = 3, y = 1.

<h3><u>Answer</u></h3>

f(3) = 1

Write the ratio as a fraction in simplest form, with whole numbers in the numerator and denominator.

\blue\textsf{\textbf{\underline{\underline{Question:-}}}}

What is the ratio in simplest form? 24 mi to 40 mi

\blue\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}}

In the ratio 24 to 40 (24:40), 24 is the numerator:-

\dfrac{24}{}

40 is the denominator:-

\displaystyle\frac{24}{40}

Now we need to simplify this fraction.

Divide the numerator and denominator by 4:-

\displaystyle\frac{6}{10}

Since the fraction is still not in its simplest form, we need to continue simplifying, but 6 and 10 aren't divisible by 4. They're divisible by 2, so we  divide by 2:-

\displaystyle\frac{3}{5}

Now just write ":" instead of the fraction bar:-

3:5

That's the ratio in its simplest form.

<h3>Good luck.</h3>
