The experimental unit is referred to as the person, animal, or object that is the subject of the experiment.

The  Experimental units is known to often receive different treatments from one another in an experiment.

The experimental method used often has a lot of manipulation of variables so as to establish cause and effect relationships.  The unit is the object to which the treatment is randomly given to. If the experimental units are human beings, they are referred to as subjects.

You can have no more than 2600 lbs on the elevator.

"Can't have no more" is a double negative and quite confusing. It actually mean you Must have more than 2600 lbs on the elevator.

500 + 140x ≤ 2600

500 - 500 + 140x ≤ 2600 - 500

140x ≤ 2100

Which of the following strategies is most helpful for protecting the soil from water erosion?
A) Alley cropping with tilled soil
B) planting crops in contour strips
C) rotating crops between different fields
D) using shelterbelts to separate crop fields

Answers

Answer:

B

Explanation:

its planting crops in contour strips :D i took the test and got this correct!

On plain terrain over a slope, contour strip cropping is advised; it is used to stop runoff (the movement of water on the soil surface), which results in a loss of soil fertility. According to studies, terracing and contour strip cropping work together to conserve soil and water. Thus, option B is correct.

What planting crops in contour strips prevent water erosion?

Contour farming's primary benefit is that it minimizes soil erosion. When it rains, traditional farming techniques that produce along straight, long, and flat slopes parallel to the flow of water accelerate up erosion since all the water flows downhill in one direction.

Therefore, contour strip cropping is the practice of cultivating crops in a grid-like pattern across a sloped field and along its contours. All the contour farming's benefits (cropping and tilling) are there, and it also offers various kinds and depths of soil cover.

If f(x)=6x²-x³, then at what value(s) of x does the tangent to the curve f(x)is parallel to line 9x=1+y?

Answers

The given line in slope-intercept form is

9x = 1 + y   ⇒   y = 9x - 1

so that its slope is 9. Any tangent to f(x) at some point (x, y) will be parallel to this line whenever f'(x) = 9 at that point.

We have

f(x) = 6x² - x³

with derivative

f'(x) = 12x - 3x²

Solve for x that makes f'(x) = 9 :

9 = 12x - 3x²

3x² - 12x + 9 = 0

x² - 4x + 3 = 0

(x - 3) (x - 1) = 0

x = 3 or x = 1
