I think that the D. CONE is the three-dimensional figure that will be formed when an equilateral triangle is rotated around the x-axis of the coordinate plane.
<span>A sphere is defined as the set of all points in space that are a fixed distance from a common point, the center.

<span>A cylinder is with two parallel congruent circular faces whose cross sections (taken parallel to these circular faces) are circular.

<span>A cube is a rectangular prism whose faces are squares.</span>
Answer:choice number 1 and 3 and 4
Step-by-step explanation:
Answer:
The boat is approximately 338.74 feet from the base of the cliff. If the problem suggests rounding to the nearest whole number, you should use 339 ft.
Step-by-step explanation:
Let's draw the right angle triangle associated with the problem (see attached image). Notice that the 305 ft height corresponds to the "opposite side" to the given acute angle of
, and that the distance we need to find is the "adjacent" side to the given acute angle. Therefore, the appropriate trigonometric function to use is the "tangent", given that from it we can solve for the unknown adjacent side "x":
![tan(42^o)=\frac{opposite}{adjacent} \\tan(42^o)=\frac{305}{x}\\x=\frac{305}{tan(42^o)}\\ x=338.74\,\, ft](https://tex.z-dn.net/?f=tan%2842%5Eo%29%3D%5Cfrac%7Bopposite%7D%7Badjacent%7D%20%5C%5Ctan%2842%5Eo%29%3D%5Cfrac%7B305%7D%7Bx%7D%5C%5Cx%3D%5Cfrac%7B305%7D%7Btan%2842%5Eo%29%7D%5C%5C%20x%3D338.74%5C%2C%5C%2C%20ft)
7728/4 = 1932
see how many times the number go into each other and subtract from the next number
