The base of a regular pyramid is a hexagon. The figure shows a regular hexagon with center C. An apothem is shown as a dashed se
tatuchka [14]
Answer: 294√3

Explanation:


1) The described hexagon has these featrues:
a) 6 congruent equilateral triangles whose side lengths measure 14
b) height of each triangle = apotema = a
c) the area of each triangle is base × a / 2 = 14 × a / 2 = 7a


2) a is one leg of a right triangle whose other leg is 14 / 2 = 7, and the hypotenuse is 14.

3) Then you can use Pythagorean theorem fo find a:

14² = 7² + a² ⇒ a² = 14² - 7² = 147 ⇒ a = √ 147 = 7√3

4) Therefore, the area of one triangle is: 14 × 7√3  / 2 = 49√3

5) And the area of the hexagon is 6 times that: 6 × 49√3 = 294√3

A 73 meters long stick is cut into two pieces. The longer piece is 16 meters longer than twice the length of the shorter piece.
MrMuchimi

Answer:

The longer piece: 54m

The shorter piece: 19m

Step-by-step explanation:

Make an equation from what is said.

One of the pieces is 'x'

The other piece is 2x+16

x + (2x + 16) = 73m

solve for x

x = 19

plug it in

2*19 + 16

you get 54

so 54 is the longer piece

and 19 is the shorter piece (x was the shorter piece)

Hope this helped :)

Terry has an investment account which compounds interest continuously at an annual interest rate of 1. 4%. After 3 years, he has
Serggg [28]

Answer:

  $1,630.08

Step-by-step explanation:

The value of an amount earning interest continuously compounded is given by the formula ...

  A = Pe^(rt)

The value of P can be found by dividing by its coefficient:

  P = A/(e^(rt)) = Ae^(-rt)

  P = $1700·e^(-0.014·3) ≈ 1630.0786

Terry placed $1,630.08 in the account.
