Answer:

Widespread water contamination caused by fertilizer runoff

Step-by-step explanation:

cotton is a profitable non-food crop in the world. about 25 million people make huge income from cotton production and about 7% labor get employed in many developing countries.

the production of cotton posses s many threat on the environment from the use of agrochemicals. The production of cotton degrades the soil severely and exposes the soil to erosion. the pesticides , fertilizers from the cotton field when been eroded causes widespread water contamination caused by fertilizer runoff.

Hello!

The key word in this is After walking 5 steps forward, Julie walked 5 steps backward

So, she walked forward 5 steps, then walked back the same steps, returning her to her starting position.

your answer is the second graph.

This graph shows what i explained: she starts at 0. goes forward 5, then back 5, returning her to 0.

I hope this helps, and have a nice day!

Which set of ratios could be used to determine if one triangle is a dilation of the other

Lisa [10]

Answer:

See explanation

$\frac{3.6}{3} = \frac{5.4}{4.5} = \frac{6}{5}$

Step-by-step explanation:

The two triangles are similar if the ratio of the corresponding sides are proportional.

The ratio of the corresponding sides are:

$\frac{3.6}{3} = 1.2$

$\frac{5.4}{4.5} = 1.2$

$\frac{6}{5} = 1.2$

The set of ratios which could be used to determine if one triangle is a dilation of the other is

$\frac{3.6}{3} = \frac{5.4}{4.5} = \frac{6}{5}$

If there are multiple correct options then check this one too.

$\frac{3}{3.6} = \frac{4.5}{5.4} = \frac{5}{6}$

Find 3/4 of 16.

16 * 3/4

48/4

12

So she uses 12 gallons of gas.

1. ) Consider the function f(x)=5−7x2,−5≤x≤1

Marat540 [252]

1.) The interval of the value of x is from -5 to 1, inclusive. Remember that what is asked is the absolute value, thus the sign does not matter even if you have to subtract x from 5. Thus, the maximum value would be obtained if the x is smaller, which is 1. The minimum value is obtained when x=-5.

Absolute maximum value: x = - 5
f(-5) = ║5 - 7(-5)^2║ = ║-170║=170

Absolute minimum value: x = 1
f(1) = ║5 - 7(1)^2║ = ║-2║= 2

2.) The Mean Value Theorem (MVT) applies to functions that are continuous and differentiable on the closed and open interval of a to b, respectively. Since the function is a quadratic function, MVT can be applied. Then, this means that there is a value of c which is between a and b. This could be determined using this formula according to MVT:

$f'(c)= \frac{f(b)-f(a)}{b-a}$

The differentiated form would be f'(x) = -2x. Then,

$-2c = \frac{(4- 0^{2} )-(4- (-1)^{2}) }{0--1}=1$

$c=- \frac{1}{2}$

Thus, x = -1, x = -1/2, and x=0 all lie in the function 4-x^2.
