A triangular parcel of land has sides of lengths 650,760 and 450 feet. Approximate the area of the land. Round answer to nearest
Marianna [84]

Answer:

145769 ft²

Step-by-step explanation:

This involves the use of Heron's formula to find the area of the triangle, given the side lengths. We will need to find the semi-perimeter of the triangle, which is half of the full perimeter.

s = semi-perimeter

s = (650+760+450)/2

s = 1860/2

s = 930

Now, using this we put it into Heron's formula to find the area.

A = √((930)(930-650)(930-760)(930-450))

A = √(930(280)(170)(480))

A = √21248640000

A = 145769.1325

A = 145769

The area of the parcel is 145769 ft²

Equations Of Parabolas (Conics) Unscramble
abruzzese [7]

The match is shown in the picture for the function of a parabola and the graph of a parabola.

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

As we know the standard form of the parabola is:

y = a(x - h)² + k

If a > 0 (parabola opens upwards)

If a < 0 (parabola opens downwards)

or

x = a(y - h)² + k

If a > 0 (parabola opens right side)

If a < 0 (parabola opens left side)

Here (h, k) is the vertex of the parabola and a is the leading term.

Thus, the match is shown in the picture for the function of a parabola and the graph of a parabola.

A rectangular prism has dimensions of 1/3, 3, and 5/3 in.
julsineya [31]

Answer:

Step-by-step explanation:

The rectangular prism has a volume equal to V=xyz. V=(1/3)3(5/3)=5/3 in^3. The cube has a volume equal to V=s^3. The volume of the cube is equal to the prism when

s^3=(1/3)(3)(5/3)\\ \\ s^3=5/3\\ \\ s=\sqrt[3]{\frac{5}{3}}in\\ \\ s\approx 1.19in
