Answer: Soil loss is caused by a variety of factors, including erosion from wind and water, mechanical tilling, logging, agricultural practices, and poor water management. Erosion and sedimentation, the major effects of soil loss, are widespread and can be devastating.

Erosion

Erosion is a natural process on hill slopes. The rate of erosion is determined by several factors, including soil type, rainfall, and length and percent of slope. Generally, human-induced changes in the landscape lead to higher levels of erosion than would occur naturally. While there are many ways to minimize erosion, vegetative cover is the most effective over the long term. Eroding road.When vegetation is removed, the rate of soil erosion is greatly accelerated, often beyond sustainable levels.

Sedimentation

Eroded soil deposited downslope is referred to as sedimentation. When severe rain or wind events occur or soils are disturbed by human

The Sedimentation Control Act of 1973 requires operators to implement short- and long-term mitigation measures to reduce erosion on- and off-site. Forest landowners who wish to harvest trees are exempt from these regulations if they comply with forestry practice guidelines, which include erosion control measures and mitigation. Best management practices (BMPs) are voluntary practices that reduce sources of se

Find the eccentricity e and the distance ldI from the pole to the directrix of the conic
nikitadnepr [17]

Answer:

The answer is "eccentricity = 0.5 and distance = 60".

Step-by-step explanation:

Given value:

\bold{r=\frac{420}{ -14 +7 \sin \theta}}

Standard equation formula:

\bold{\to r=\frac{ep}{1- e \sin \theta}}

\to r=\frac{\frac{420}{-14}}{1- \frac{7}{14} \sin \theta}\\\\\to r=\frac{ -30 }{1- \frac{1}{2} \sin \theta}\\\\\to r=\frac{ -30 }{1-  0.5 \sin \theta}\\\\

\boxed{ r=\frac{-30 }{1- 0.5 \sin \theta}}

compare the above value with the Standard equation:

\to e=0.5 \\  \to ep= -30\\

calculating the value of p:

\to 0.5 p= -30\\\\\to p= \frac{-30}{0.5}\\\\\to p= \frac{-300}{5}\\\\\to p= - 60

eccentricity  (e) = 0.5

distance = - 60

distance |d| =  60

Point D is on segment BC. Segment BC measures 8x units in length.
Lynna [10]
Line BC = Line CD + Line DB
8x=3x+8+4x+10
8x=7x+18
8x-7x=18
x=18

Hence, length BC = 18×8 = 144

12. Niki is going to the Pasco County Fair and she wants to go on as many rides as she can.It costs $7.50 to get into the fair a
Masteriza [31]

The admission fee to the Fair is $7.50

The rides cost 50c each.

Let x be the number of rides she can take.

You can express her expenses in the fair as an equation:

C= total cost

C=7.50+0.5x → from this equation you can calculate how many rides she will be able to get on.

If she has a total of $23 to spend, then the number of rides can be calculated as:

\begin{gathered} C=7.50+0.5x \\ 23=7.50+0.5x \\ 23-7.5=0.5x \\ 15.5=0.5x \\ x=\frac{15.5}{0.5} \\ x=31 \end{gathered}

With $23 she will be able to go on 31 rides.
