If a line has a positive slope what is its general direction

1 answer:

6 0

In discussing graphs, we generally agree to move from left to right. If a line has a positive slope, then the function (and the line that represents it) is rising as we move from left to right, as in / .

Exam;ple: y=x is a straight line with the positive slope 1. As x increases, y increases by the same amount.

Total profit P is the difference between total revenue R and total cost C. Given the following total-revenue and total-cost fu

gavmur [86]

Answer:

The profit function is:

$P(x)=-x^2+1280x-3300$

The maximum value is 406, 300 occurring when x = 640.

Step-by-step explanation:

The revenue function is:

$R(x)=1300x-x^2$

And the cost function is:

$C(x)=3300+20x$

Then the total profit function will be:

$P(x)=R(x)-C(x)=(1300x-x^2)-(3300+20x)=-x^2+1280x-3300$

This is a quadratic function.

Therefore, the maximum value of the total profit will occur at its vertex point.

The vertex of a quadratic is given by:

$\displaystyle \Big(-\frac{b}{2a}, f\Big(-\frac{b}{2a}\Big)\Big)$

In this case, a = -1, b = 1280, and c = -3300.

Then the point at which the maximum profit occurs is at:

$\displaystyle x=-\frac{1280}{2(-1)}=640$

And the maximum profit will be:

$P(640)=-(640)^2+1280(640)-3300=406300$

Alla [95]

Answer:

H. 2 3/4

Step-by-step explanation:

DATE >> WATER LEVEL CHANGE (inches)
August 25 >> -0.75
September 8 >> -1 3/ 8
September 22 >> 2.5
October 6 >> -1/2
October 20 >> 1 7/8

<u>Total change:</u>

1 7/8 - (-0.75) =
1+ 7/8 + 3/4 =
1 + 7/8 + 6/8 =
1 + 13/8 =
1+ 1 5/8 =
2 5/8

The closest answer option is H. 2 3/4

Find the next four terms of the arithmetic sequence 11,15,19...

wariber [46]

Each new term of this arith. seq. is obtained by adding 4 to the previous term. Hence, 15 = 11+4; 19=15+4, and so on. Add 4 to 19 to get the next term. Keep going until you have 4 new terms for the arith. seq. 11, 15, 19, .....
