Answer:

No

Step-by-step explanation:

the ratio between AD and DE is 3:1.

The geometric centroid (center of mass) of the polygon vertices of a triangle is the point D which is also the intersection of three triangle's medians.

The centroid theorem states that the centroid is 2/3 of the distance from each vertex to the midpoint of the opposite side.

A company produces remote-controlled helicopters. The company’s profit, in thousands of dollars, as a function of the number of
muminat

Answer:

When 6 helicopters are produced weekly, the company's profit is <u>14 thousand dollars.</u>

Step-by-step explanation:

As per the given statement:

The company profit (in thousands of dollars), as a function of the number of helicopters produced per week can be modeled by a  function.

The function that models the scenario is:

f(h) = -2(h-4)^2 +22                       ......[1]

where

f(h) represents the company's profit

h represents the number of helicopters produced per week.

It is also given that when 1 helicopter is produced per week, the company’s profit is 4 thousand dollars.

Maximum profit for company 22 thousand dollars, occurs when 4 helicopters are produced per week

⇒f(1) = 4 and f(4) = 22

we have to find when 6 helicopters are produced weekly, the company profit is;

⇒  h = 6 helicopters

Substitute this value in [1] to solve for f(6);

f(6) = -2(6-4)^2 +22

=-2(2)^2 +22 = -2 \times 4 + 22 = -8 + 22 = 14

Therefore, the company profit is, 14 thousand dollars.
