Question

Your buddy in mechanical engineering has invented a money machine. The main drawback of the
machine is that it is slow. It takes one year to manufacture $100. However, once built, the machine
will last forever and will require no maintenance. The machine can be built immediately, but it will
cost $1000 to build. Your buddy wants to know if he should invest the money to construct it. If the
interest rate is 9.5% per year, what should your buddy do? 
How would your answer to Problem change if the machine takes one year to build?

Answer 1

Explanation:

Answer:

Altitude = 200 m

Step-by-step explanation:

According to the information provided in the question it is given as

Field is in the form of triangle

Area =3.5 ha =Hacter

Base length = 350 m

We need to find its altitude

Here Area = 3.5 ha = 35000 m

Area of triangle = \begin{gathered}\frac{1}{2} \times base \times height\\\end{gathered}

2

1

×base×height

By substituting the values we get the answer

\begin{gathered}35000 = \frac{1}{2} \times 350\times h\\\end{gathered}

35000=

2

1

×350×h

\begin{gathered}35000\times 2= 350h\\70000=350h\\h=\frac{70000}{350} \\\end{gathered}

35000×2=350h

70000=350h

h=

350

70000

No converting into lowest term we get

h= 200 mh=200m

Hence altitude = 200 m

soory if I send wrong
