We want to get the price per acre that she receives for the land, we will get that the price per acre is $2,777.8

First, we need to find the total area of the land.

There are two parcels, one with an area of 1 mi^2, and the other with dimensions of one-mile x half a mile, then the area of the other parcel is:

A' = (1 mi)*(0.5 mi) = 0.5 mi^2

The total area is the sum of these two, we get:

1 mi^2 + 0.5 mi^2 = 1.5 mi^2

And notice that we want to get the price per acre, knowing that:

1 mi^2 = 640 acres, then:

1.5 mi^2 = 1.5*(640 acres) = 900 acres.

The price per acre is equal to the quotient between the total price for the area and the number of acres, this gives:

P = ($2,500,000)/(900 acres)  = $2,777.8

So each acre costs $2,777.8

The height of the bottom of the hole after the second day is -35 11/12 feet

Given:

Day 1 height = -45 1/4 feet

Day 2 height = -45 1/4 + 9 1/3

= - 181/4 + 28/3

= (-543 + 112) / 12

= -431/12

= -35 11/12 feet

Therefore, the height of the bottom of the hole after the second day is -35 11/12 feet

Answer:

c

Step-by-step explanation:

Answer:

B) Line A has a greater slope than Line B.

Step-by-step explanation:

When looking at [tex]f(x)=4x-9[/tex] is basically the same way of saying [tex]y=4x-9[/tex]

which is in slope-intercept form. Because of that, we know that the slope of line A is 4.

To find the slope of line B we have to use the slope formula

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

[tex]m=\frac{7}{2}[/tex] as a decimal [tex]m=3.5[/tex]

So line A slope = 4 and line B slope = 3.5

Which makes line A slope greater than line B slope

So, first of all, we know that Cell and DNA Replication are different just by looking at their names.

Cell Replication is to replicate cells and not DNA whereas DNA replication replicates DNA but not cells.

We do know that DNA resides inside Cells what we call eukaryotes.

So, in short, no, they are different things.

Answer:

A perfect square is an integer that results in another integer when square rooted.

Step-by-step explanation:

For example:

16 is a perfect square because [tex]\sqrt{16}[/tex] = 4.

16 and 4 are both integers

Also, notice that 4 x 4 = 16

Answer:

A perfect square is a number that can be multiplied together by the same numbers/digits/values.

Step-by-step explanation:

Examples:

√25

5 times 5 is 25 thus √25 is a perfect square

√144

12 times 12 is 144 thus √144 is a perfect square

Answer:

Neither

Step-by-step explanation:

Parallel lines need to have the same slopes, but lines A and B have different slopes, so parallel is off the list.

Perpendicular lines need slopes that multiply to -1, meaning one of them must be negative. This is not possible if both are greater than 1, making them positive. The lines cannot be perpendicular.

If they are the same line, they need the same slopes. However, they have different slopes, making this option impossible.

We are left with neither.

Answer:

slope= -¾

[tex]y - intercept = 2 \frac{1}{4} [/tex]

Step-by-step explanation:

3x +4y= 9

Let's rewrite the equation into the form of y= mx +b (known as slope-intercept form), where m is the slope and b is the y-intercept.

Keep the y term on the left-hand side of the equation and move all the other terms to the right-hand side.

4y= -3x +9

For the coefficient of y to be 1, divide both sides of the equation by 4.

[tex]y = - \frac{3}{4} x + \frac{9}{4} [/tex]

[tex]y = - \frac{3}{4} x + 2 \frac{1}{4} [/tex]

[tex]slope = - \frac{3}{4} [/tex]

[tex]y - intercept = 2 \frac{1}{4} [/tex]

Answer:

Parallel

Step-by-step explanation:

Simplify the functions to [tex]y=mx+b[/tex]

A: [tex]y=1/4x-5[/tex]

and

B: [tex]y=1/4x+3/4[/tex]

Since these lines have the same slopes and different y-intercepts, they are parallel

The resulting function is presented in the image attached below.

In this question we know the graphic of a function and we must draw a new function which is the reflection of the original one around the x-axis. Mathematically speaking, a reflection a around the x-axis is defined by the following operation:

[tex]f'(x) = f(x) - 2\cdot [f(x) - 0][/tex]

[tex]f'(x) = - f(x)[/tex] (1)

Which means that the reflected function is equal to the original function multiplied by -1.

Now, we proceed to represent the reflected function graphically.
