What's the shape of what the farmer is fencing?

Answer:

square of  each side=38 ft

Step-by-step explanation:

square has the largest area.

each side=152/4=38ft

alternatively

let x and y be the sides

2x+2y=152

x+y=76

y=76-x

area A=xy=x(76-x)=76x-x²

\frac{dA}{dx} =76-2x\\\frac{dA}{dx} =0,gives ~76-2x=0\\2x=76\\x=76/2=38 \\\frac{d^2A}{dx^2} =-2

Please help!!!!! I have no idea what to do!
Phantasy [73]

Answer:

f(x)=-\frac{1}{2}x +1

Step-by-step explanation:

Slope intercept form is: f(x)=mx+b

<h2>Find the Slope:</h2>

Choose 2 points on the graph:

(0,1) (2,0)

Find the slope of the two points:

\frac{0-1}{2-0}=-\frac{1}{2}

m=-\frac{1}{2}

<h2>Find the Y-Intercept</h2>

The y-intercept, or the point that the line crosses on the y axis, is (0,1).

b=1

f(x)=-\frac{1}{2}x +1

In the diagram mz3= x+ 30 and mz4 =2x-80. What is the measure of angle 3?
Andreas93 [3]

Given:

Consider the below figure attached with this question.

m\angle 3=(x+30)^\circ and m\angle 4=(2x-80)^\circ.

To find:

The measure of angle 3.

Solution:

From the below figure it is clear that, angle 3 and angle 4 are vertically opposite angles.

We know that, vertically opposite angles are always equal. So,

m\angle 3=m\angle 4

(x+30)^\circ=(2x-80)^\circ

x+30=2x-80

x-2x=-30-80

-x=-110

x=110

Now,

m\angle 3=(110+30)^\circ

m\angle 3=140^\circ

Therefore, the measure of angle 3 is 140 degrees.

Solve for x<br> pls show work<br> 1/2x + 4 = 1/8x + 88
SVETLANKA909090 [29]

Answer:

224

Step-by-step explanation:

1/2x+4=1/8x+88

1/2x-1/8x+4=88

1/2x-1/8x=88-4

4/8x-1/8x=84

3/8x=84

x=84/(3/8)

x=(84/1)(8/3)

x=672/3

x=224
