A farmer needs to enclose two adjacent rectangular pastures. How much fencing does the farmer need?

1 answer:

3 0

W=width of the pasture, and
320000/w=length (parallel to river) 
F=twice width + length 
=2w + 320000/w 

Find derivative of F with respect to w and equate to zero to find w. 
i.e. 
Solve for w in 
dF/dw=0

H(a)=2a+4 g(a)-2a^2+2 find (h+g)(a+3)

Lunna [17]

Answer:

hello :

(g/f)(3) = g(3)/f(3)

but : g(3) =3(3)+2 = 11

f(3) 2(3)-4 = 2

g/f)(3) = 11/2

Which of the following could not be points on the unit circle?

NemiM [27]

A. √(0.8^2) + (0.6^2) = √1 = 1 => OK

b.(-2/3,√ 5/3) = √(-2/3)^2 + 5/9) = √(4/9 +5/9) = √1 = 1 => OK

c.(√ 3/2, 1/3) = √(3/4 + 1/9) < 1 => it is inside the unit circle

d.(1,1) = √(1 + 1) = √2 > 1 => NO. This point is beyond the limits of the unit circle.

Write the equation in standard form of the line that has x-intercept 6 and y-intercept -2.

zysi [14]

Answer:

x - 3y = 6

Step-by-step explanation:

Equation of the line in intercept form

The intercept form of the equation of a line is:

$\displaystyle \frac{x}{a}+\frac{y}{b}=1$

Where:

a = x-intercept

b = y-intercept

The standard form of a line is:

Ax + By = C

The given line has a=6 and b=-2, thus:

$\displaystyle \frac{x}{6}+\frac{y}{-2}=1$

Multiplying by 6:

x - 3y = 6

This is the required standard form of the line.

Thus, the standard form of the line is:

x - 3y = 6
