Procedure:

1) Integrate the function, from t =0 to t = 60 minutues to obtain the number of liters pumped out in the entire interval, and

2) Substract the result from the initial content of the tank (1000 liters).

Hands on:

Integral of (6 - 6e^-0.13t) dt  ]from t =0 to t = 60 min =

= 6t + 6 e^-0.13t / 0.13 = 6t + 46.1538 e^-0.13t ] from t =0 to t = 60 min =

6*60 + 46.1538 e^(-0.13*60) - 0 - 46.1538 = 360 + 0.01891 - 46.1538 = 313.865 liters

2) 1000 liters - 313.865 liters = 613.135 liters

Answer: 613.135 liters

30 POINTS!!! Kent won 25% of the games he played on Saturday. If he lost 12 games on Saturday, and no game ended in a tie, how m
Lana71 [14]

Answer:

He won 4 games

Step-by-step explanation:

Percentage of games he lost= 75%

Let the total number of games be x

75% of x = 12

\frac{75x}{100} = 12

75x= 12 x 100

x= \frac{1200}{75}

 =16

Number of games he won = 16-12

                                            = 4

What is the value of the 9th term in the following geometric sequence?
earnstyle [38]

Answer:  The correct option is (D) 196608.

Step-by-step explanation:  We are given to find the value of the 9th term in the following geometric sequence :

3,     12,    48,    192,    .     .     .

We know that

the n-th term of a geometric sequence with first term a and common ratio r is given by

a_n=ar^{n-1}.

For the given sequence, we have

first term, a = 3  and the common ratio, r is given by

r=\dfrac{12}{3}=\dfrac{48}{12}=\dfrac{192}{48}=~~.~~.~~.~~=4.

Therefore, the 9th term of the given sequence will be

a_9=ar^{9-1}=3\times 4^8=3\times65536=196608.

Thus, the required 9th term of the given sequence is 196608.

Option (D) is CORRECT.

What has a steeper line y=2x-3 or x-5y=20
Montano1993 [528]
Y=2x-3 has a steeper line because the bigger the slope, the more it goes up on the y-axis for every one spot on the x-axis. 
The first one goes up 2 spaces for every one it goes over, and the second one goes up one space for every 5 it goes over

An airplane's altitude changes -378 feet over 7 minutes. What was the mean change of altitude in feet per minute?
Sveta_85 [38]
<h2>Answer:</h2>

<u>The mean altitude will be</u><u> -54 per minute</u>

<h2>Step-by-step explanation:</h2>

We are given with altitude change as -378 feet over 7 minutes

Now

We need feet per minute

So -378 / 7 will give us the altitude change per minute

-378 / 7 = -54

Therefore the mean change of altitude in feet per minute is -54 per minute
