Answer:

x = +√96 = +√(16*6) = + 4√6

Step-by-step explanation:

Note that this is a large triangle with 2 smaller, similar triangles inside. The base of the large triangle is 10, so the base of either of the smaller triangles is half that, or 5. These are all right triangles. We can now apply the Pythagorean Theorem to find x.

According to this Theorem, x² + 5² = 11², so that x² = 121 - 25 = 96.

Taking the positive square root to be the desired side length x,

x = +√96 = +√(16*6) = + 4√6

using the graph,find the value of the constant in the equation below.if necessary,round your answer to the nearest integer (Pict

Ugo [173]

The equation is the form:
Height = Constant / Width

There are several points that can be used to determine the constant. Picking out one which is (4,20)
20 = Constant / 4
Constant = 4(20)
Constant = 80

The constant is 80.

Suppose you want to fence in some land along the edge of a straight river. the fenced area will be in the shape of a rectangle,

m_a_m_a [10]

For the largest area, half the fence is used parallel to the river, and the other half is used for the two ends of the rectangular space.

The dimensions are 475 m by 237.5 m.

_____
Let x represent the length along the river. Then the area (A) is found as
.. A = x*(950 -x)/2
This equation describes a parabola with its vertex (maximum) halfway between the zeros of x=0 and x=950. That is, the maximum area is achieved when half the fence is used parallel to the river.
