Answer:

47/45 = 1 2/45

Step-by-step explanation:

- If you would like a more in-depth explanation please let me know. Hope this helps!

- First you have to find a common denominator. This will be 45.

- Now, figure out what you multiply to get 45. For example...

4 = 12 + 7 = 35 (add these up)

15 45 9 45 It should equal 47/45 = 1 2/45.

Answer:

Line z2 : Point L

Line z1 : Point A

Step-by-step explanation:

To find the complex conjugate you flip the sign of the complex number but keep the same magnitudes.

For line z2 we can see that one of the points is $6-7i$ . To find the complex conjugate we just flip the sign. So the complex conjugate is $6+7i$ .

This means that the complex conjugate of line z2 can be represented with point: L

For line z1 we do the same thing. $1-2i$ goes to $1+2i$ . This can be represented with the point A

A farmer is tracking the amount of corn his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 50 models

Answer:

The crop yield increased by 9 pounds per acre from year 1 to year 10.

Step-by-step explanation:

To solve this we are using the average rate of change formula: $Av=\frac{f(x_2)-f(x_1)}{x_2-x_1}$ , where:

$x_2$ is the second point in the function

$x_1$ is the first point in the function

$f(x_2)$ is the function evaluated at the second point

$f(x_1)$ is the function evaluated at the first point

We know that the first point is 1 year and the second point is 10 years, so $x_1=1$ and $x_2=10$ . Replacing values:

$Av=\frac{-(10)^2+20(10)+50-[-(1)^2+20(1)+50]}{10-1}$

$Av=\frac{-100+200+50-[-1+20+50]}{9}$

$Av=\frac{150-[69]}{9}$

$Av=\frac{150-69}{9}$

$Av=\frac{81}{9}$

$Av=9$

Since $f(x)$ represents the number of pounds per acre and $x$ the number of years, we can conclude that the crop yield increased by 9 pounds per acre from year 1 to year 10.
