Step-by-step explanation:

We are asked to graph the equation of an ellipse given by \frac{x^2}{36}+\frac{y^2}{49}=1.

We know that standard from of an ellipse \frac{x^2}{a^2}+\frac{y^2}{b^1}=1, when a>b, then the ellipse will be horizontal and when a, then the ellipse will be vertical.

We can rewrite our given ellipse as: \frac{x^2}{6^2}+\frac{y^2}{7^2}=1.

Upon looking at our given ellipse we can see that the horizontal radius is less than vertical radius, so our ellipse will be a vertical ellipse. The center of our ellipse is at origin (0,0).

Upon graphing our ellipse, we will our required graph as:

A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the mi
EleoNora [17]

Answer:

c) 120 ft

Step-by-step explanation:

Let's consider the rhombus has 4 sides, A, B, C, and D.

To find the length of each side, let's first find the length AE.

From the diagram, AE is half of AC and AC = 30 ft.

Therefore,

AE = ½ * 30

AE = 15 ft

Let's find the length AD, since we are looking for the distance around the perimeter.

AD = \frac{15}{sin30} = \frac{15}{0.5} = 30 ft

We are told the rhombus is formed by four identical triangles.

Therefore the distance around the perimeter would be: AD+AD+AD+AD=

30 ft + 30 ft + 30 ft + 30 ft

= 120 ft

The distance around the perimeter of the garden is 120 ft

h is measured in miles so you need to convert 1135ft to miles

1 mile = 5280 feet

 so 1135/5280 = 0.21496 miles

D = sqrt(2(3960)(0.21496) + 0.21496^2)

D = sqrt(1702.4832 + 0.046207801)

D = sqrt(1702.529408

D = 41.2617 miles round answer as needed
