A square pyramid has sides of 8 m. Each face is an equilateral triangle.

Annette [7]

Lateral Area means Area of all four triangles

Now area of 1 triangle = $\frac{\sqrt{3}}{4} a^2 = \frac{\sqrt{3}}{4} 8^2$

= $\frac{\sqrt{3}}{4} * 64 = 16\sqrt{3}$ square meters

Now for four triangles we multiply by 4

Lateral area of pyramid = $4* 16\sqrt{3} = 64\sqrt{3}$ m^2

that is Option D

suppose the annual rate of inflation is about 4% this means that the cost of an item increases by about 4%. write and evaluate a

Mashcka [7]

Cost = (3,500) * (1.04)^years
Cost = (3,500) * (1.04)^4
Cost = (3,500) * 1.16985856 
Cost = 4,094.50

There are 21 more days before the first big winter storm and the squirrel collects 12 acorns a day, how far away from her origin

alexandr402 [8]

She has 445 left after the bear ate some so
21 × 12 = 252
252 + 445 = 697 acorns

she should maybe bother the bear so he can't hibernate, or steal his food so he knows what it's like

How do you find the parameterization of a helix?

Marina CMI [18]

Answer:

$\left\{\begin{array}{l}x=r\cos t\\ \\ y=r\sin t\\ \\z=at\end{array}\right.$

Step-by-step explanation:

A helix is a curve for which the tangent makes a constant angle with a fixed line. The shortest path between two points on a cylinder (one not directly above the other) is a fractional turn of a helix, as can be seen by cutting the cylinder along one of its sides, flattening it out, and noting that a straight line connecting the points becomes helical upon re-wrapping (see attached diagram for helix).

The parametrization for the helix is

$\left\{\begin{array}{l}x=r\cos t\\ \\ y=r\sin t\\ \\z=at\end{array}\right.,$

where $r$ is the radius of the helix, $a$ is the constant, and $t\in [0,2\pi )$ is the parameter
