M (AOC) = 70, m (COE) = 60; B is bisect AOC; OD is bissertriz Coe; calculate the extent of BOD.

1 answer:

7 0

$m\angle BOD=m\angle BOC+m\angle COD\\\\
m \angle BOC=\dfrac{1}{2}m \angle AOC=\dfrac{1}{2}\cdot70=35\\
m \angle COD=\dfrac{1}{2}m \angle COE=\dfrac{1}{2}\cdot60=30\\\\
m\angle BOD=35+30=65$

You are designing a rectangular garden. the garden will be enclosed by fencing on three sides and by a house on the fourth side.

RUDIKE [14]

Suppose the dimensions of the rectangle is x by y and let the side enclosed by a house be one of the sides measuring x, then the sides that is to be enclosed are two sides measuring y and one side measuring x.

Thus, the length of fencing needed is given by

P = x + 2y

The area of the rectangle is given by xy,

i.e.

$xy = 288 \\ \\ \\ \\ \Rightarrow y= \frac{288}{x}$

Substituting for y into the equation for the length of fencing needed, we have

$P=x+2\left( \frac{288}{x} \right)=x+ \frac{576}{x}$

For the amount of fencing to be minimum, then

$\frac{dP}{dx} =0 \\ \\ \Rightarrow1- \frac{576}{x^2} =0 \\ \\ \Rightarrow \frac{576}{x^2} =1 \\ \\ \Rightarrow x^2=576 \\ \\ \Rightarrow x=\sqrt{576}=24$

Now, recall that

$y= \frac{288}{x} = \frac{288}{24} =12$

Thus, the length of fencing needed is given by

P = x + 2y = 24 + 2(12) = 24 + 24 = 48.

Therefore, 48 feets of fencing is needed to enclose the garden.

Im not sure what that means but i can try...

Im not sure the order to put them in but the positive line is

y>1/2x-1

And the negative line is

Y<=3x+1

(I couldn’t find a less than and equal to sign)
