The account executive of a brokerage firm has recommended that one of her customers consider stock from five aerospace companies

soldier1979 [14.2K]

Answer:

180 ways

Step-by-step explanation:

Aerospace companies (A) = 5

Energy development companies (D) = 3

Electronics companies (E) = 4

Number of aerospace stocks bought (a) = 2

Number of Energy development stocks bought (d) = 2

Number of Electronics stocks bought (e) = 2

The number of ways that the investor can select his six investments from the recommended list is given by the combination of picking two out five aerospace companies, multiplied by picking two out three energy development companies, multiplied by picking two out four electronics companies:

$n=\frac{5!}{(5-2)!2!}*\frac{3!}{(3-2)!2!}*\frac{4!}{(4-2)!2!}\\ n=10*3*6\\n=180\ ways$

There are 180 ways for the investor to select the six companies.

Two ropes, AD and BD, are tied to a peg on the ground at point D. The other ends of the ropes are tied to points A and B on a fl

LenKa [72]

We only need to find the heights of the 2 points on the flagpole and then subtract them. We have that AC and DC are related by the following trigonometric number: tan60=AC/DC. This is because ADC is a right triangle and AC is the opposite leg of the angle we know, while DC is the adjacent leg.
$tan60= \sqrt{3} =AC/5 \sqrt{3} \\ AC=5 \sqrt{3} * \sqrt{3} =5*3=15$ .

Thus, we have calculated AC. The same remarks apply to the triangle BCD; However, now we get that tan30=BC/DC.
$tan60= 1/\sqrt{3} =BC/5 \sqrt{3} \\ BC=5 \sqrt{3} / \sqrt{3} =5$ .

Hence, the height of point B is 5 feet, while the height of point A is 15 feet. Their distance is 10 feet.
