An equivalent fraction for 12/16 is 3/4 which is the simplest form but you another one would be 6/8
a) After 4 years the profit will change from negative to positive.
b)after 4 years the profit will be lowest.
Because the equation is a quadratic equation so, it will be increasing.
c) after 4 years the profit will be 5.
<u>Step-by-step explanation:</u>
a) After 1 year = 2(1) -6(1) -3
= 2-9
= -7
It's negative
After 2 years = 2(4) -6(2) -3
= 8-12-3
= -7
It's negative
After 3 years = 2(9) -6(3) -3
= 18 - 18 -3
= -3
It's negative
After 4 years = 2(16) -6(4) -3
= 32 -24-3
= 5
It's positive
After 4 years the profit will change from negative to positive
b) after 4 years the profit will be lowest.
Because the equation is a quadratic equation so, it will be increasing.
c) profit = 2(16) - 6(4) -3
= 32 -24 - 3
= 5
after 4 years the profit will be 5
Area = π x r^2
Area = π x 12^2
Area = 144π or 452.16 square units. ( using 3.14 for PI)
Circumference = 2*PI *radius
Circumference = 12π or 37.68 units ( using 3.14 for PI)
