That is true. It is much cheaper and economically safer for farms to not grow organic foods. I’m fact, sometimes it is even better for the environment for food to not be grown organically as it puts less stress on the farmland.

Find the area of the region defined by the region defined by the inequality 2|x| + 3|y-1| ≤ 6
EleoNora [17]

If x and y-1 have the same sign, then either

x>0,y>1 \implies 2|x| + 3|y-1| = 2x + 3(y-1)=6 \implies 2x + 3y = 9

or

x

If x and y-1 have opposite sign, then

x>0,y

or

x1 \implies 2|x| + 3|y-1| = -2x + 3(y-1) = 6 \implies 2x-3y = -9

This is to say that the region has boundaries given by these two sets of parallel lines, so we can equivalently describe the region with the set

R = \left\{(x,y) \mid -3\le2x+3y\le9 \text{ and } -9\le2x-3y\le3\right\}

The area of R is given by the double integral

\displaystyle \iint_R dx\,dy

To compute the area, change the variables to

\begin{cases}u = 2x + 3y \\ v = 2x - 3y\end{cases} \implies \begin{cases}x = \frac14(u+v) \\ y = \frac16(u-v)\end{cases}

The Jacobian for this transformation is

J = \begin{bmatrix} x_u & x_v \\ y_u & y_v \end{bmatrix} = \begin{bmatrix}1/4 & 1/4 \\ 1/6 & -1/6\end{bmatrix}

with determinant \det(J) = -\frac1{12}. Then the integral transforms to

\displaystyle \iint_R dx\,dy = \iint_R |J| \, du \, dv = \frac1{12} \int_{-3}^9 \int_{-9}^3 dv\, du

which is 1/12 the area of a square with side length 12. Hence the integral evaluates to

\displaystyle \iint_R dx\,dy = \frac1{12}\times12^2 = \boxed{12}.

The extended warranty on a garage door is $238. If the warranty costs 35% of the purchase price, how much does the garage door i
-BARSIC- [3]

Answer:

d. $680.

Step-by-step explanation:  

Let x be the cost of garage door.

We have been given that the extended warranty on a garage door is $238 and the warranty costs 35% of the purchase price. This means 35% of x equals 238.

We can represent this information in an equation as:

\frac{35}{100}x=238

0.35x=238

x=\frac{238}{0.35}

x=680

Therefore, the cost of garage is $680 and option d is the correct choice.

Do you understand how to do this?
goldenfox [79]

Answer:

189.27

Step-by-step explanation:

rounded front part has a diameter of 10

that means it has a radius of 5

rounded part's area is area of a cirlcle ÷ 2

area of a circle is pi * radius squared

pi*25=78.54

78.54÷2=39.27

rest of the shapes area is 10 times 15 which = 150

150+39.27=189.27
