The function f(3) = 50.000(0.975)", where x represents the underwater
valentina_108 [34]

9514 1404 393

Answer:

  316 lumens/m²

Step-by-step explanation:

We assume your intensity function is ...

  f(x) = 50,000(0.975^x) . . . . x meters below the surface

__

Use 200 for x and do the arithmetic.

  f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²

Ken normally leaves work at 5:00 pm, but he is leaving 20 minutes late today. He decides to make up time by taking the toll road
kobusy [5.1K]

Answer:

The correct answer is: y=\frac{1}{3} x + 20

Step-by-step explanation:

As stated in the question that x represents the number of minutes his <em>normal</em> commute takes. Here the keyword is normal; in the <em>normal</em> commute, Ken takes side streets instead of the toll road.

However, in this scenario, we have to come up with the equation that takes Ken's commute via <em>toll road</em>.

Ken can travel 3 times faster by taking the toll road (Given), which can be represented in the mathematical terms in terms of x as follows:

x_{toll\_road}=\frac{1}{3}x

<em>Without considering Ken getting late, </em>the equation would become the following:

y=\frac{1}{3} x --- (A)

<em>As Ken is leaving late</em>, we have to incorporate that time as well by <em>adding</em> it in the aforementioned equation (A).

In this case, it's 20 minutes; therefore, the equation (A) will become:

y=\frac{1}{3} x+20

Hence, the correct answer is y=\frac{1}{3} x + 20.

Here is the table of values:

Minutes   Total cost

0                 $3

1                   $3.80

2                  $4.60

3                  $5.40

The equation representing the total cost is C = $3 + $0.80tt

<h3>What is the total cost?</h3>

The total cost of using a computer is a function of the initial charge, cost per minute and total number of minutes the computer was used.

Total cost = initial charge + (cost per minute x number of minutes)

C = $3 + ($0.80 x tt)

C = $3 + $0.80tt

Total cost when the computer is used for one minute:  C = $3 +( $0.80 x 1) = $3.80

Total cost when the computer is used for two minutes:  C = $3 +( $0.80 x 2) = $4.60

Total cost when the computer is used for three minutes:  C = $3 +( $0.80 x 3) = $5.40
