Answer:

2 hours

Step-by-step explanation:

Let x be the time, in hours, for which the cost of Rollaround and Spinaround are the same.

Rollaround Cost (Cr):    Cr = $5 + $3x

Spinaround Cost (Cs):  Cs = $8 + $1.50x

We want to find the value of x that makes Cr = Cs

Cr = Cs

$5 + $3x = $8 + $1.50x

$1.50x = $3

x = 2 hours

====

CHECK:

Cr = $5+$3(2) = $11

Cs = $8+$1.50(2) = $11

At 2 hours, both cost the same.

Answer:

Table 3

Step-by-step explanation:

The ratio of x and y is not constant.

The y=x(1-x)-(1-x²) is a linear value that is not absolute.

Simplifying,

y=x(1-x)-(1-x²)

y=x-x²-1+x²

y=x-1

Thus, it is a linear equation with a negative value therefore it is not an absolute value.

Ax+By=C is the general form of a two-variable linear equation. When the equation is written in this manner, it is quite simple to obtain both segments (x and y).

Any polynomial that can be rewritten in the canonical form is a quadratic equation. where x represents an unknown quantity and a, b, and c represent known quantities, with a = 0. This indicates that f(x) = 0 is the root of function f(x) = ax2 + bx + c, which is the answer to the quadratic equation ax2 + bx + c = 0.

The absolute value of a real figure x, denoted by |x|, is the non-negative real value of x, regardless of its sign.

The collection of all points in the plane with the form (x, f(x)) that make up a function f's graph. Alternatively, we may say that the graph of f is the graph of the equation y.

A function is a type of rule that produces one output for a single input. Source of the image: Alex Federspiel. This is illustrated by the equation y=x2. Any input for x results in a single output for y. Considering that x is the input value, we would state that y is a function of x.

Answer:

Step-by-step explanation:

1) First find the y-intercept point

You can find it easily by finding the number without the variable. In this case, it is -1. With this draw a point on the y-axis line down to -1.

2) Find the slope.

Next, you can find a point by substituting a number for x. So in this example, I will be subbing x for 1.

y = -3(1) - 1

y= -3 - 1

y= -4

So there will be a point at (1,-4).

3) Graphing.

After you find that you can easily draw a straight line through both points.

The most appropriate choice for revenue and profit will be given by-

Profit expected from a 100-well drilling program = $[tex]146.2[/tex]

What is revenue and profit?

Total income generated by sale of goods and service is called revenue.

If [tex]p[/tex] is the cost of producing one unit of a commodity and [tex]q[/tex] is the number of units of the commodity, then the product of [tex]p[/tex] and [tex]q[/tex] gives the revenue.

If the revenue obtained by selling a commodity is more than the cost, difference between revenue and cost gives the profit.

Here,

Number of economic wells = 11

An economic well produces an average income of $23

Revenue obtained = $[tex]$[/tex][tex](23 \times 11)[/tex]

Number of dry wells = [tex]100 - 11[/tex]

                                  = [tex]89[/tex]

Average cost of a dry hole is $1.2 million

Cost of 89 dry holes = $[tex]$[/tex][tex](89 \times 1.2)[/tex]

                                   = $[tex]106.8[/tex]

Profit = Revenue - cost

         = $[tex](253-106.8)[/tex]

         = $[tex]146.2[/tex]

Profit  expected from a 100-well drilling program = $[tex]146.2[/tex]

Step-by-step explanation:

The maximum Area that can be enclosed will be 5000 square feet.

In the given question, it is stated that 200 feet of fencing will be done to enclose a rectangular plot with borders on a river. It has a long side on the border of a river which does not needs fencing. We need to find out the Length and Width of the plot that will maximize the area and also find out the Maximum area that can be enclosed.

It is given that the total length of the fence is 200 feet.

Let the length of the plot be l

let the width of the plot be w

=> Total Perimeter will be = l + 2w because the longer side or 1 side of length does not need fencing. Putting the perimeter as 200 we get

=> l + 2w = 200     => Equation (1)

Now, we know the Area of the plot will be l*w,

By equation (1) we get l = 200 - 2w, Putting the values in the Area:

=> Area = (200-2w) * w

=> A = 200w - 2w²

For maximum Area, the derivative of A with respect to w will be 0

=> [tex]\frac{dA}{dW} = 200 - 4w[/tex]

=> [tex]0 = 200 - 4w[/tex]

=> w = 50

Putting w = 50 in Equation (1) we get

=> l = 100

We got our Length l = 100 feet, and Width w = 50 feet. Now we will Calculate the maximum Area to enclose.

=> Area = l*w

=> A = 100*50

=> A = 5000

Hence, the Maximum area to enclose will be 5000 square feet.
