Set up an equation.
width = x
length = 56 - 2x
Multiplying length * width makes area. 56x - 2x^2 = Area.
y = -2x^2 + 56x
Ax^2 + Bx = C
Solve for the vertex: x = -(b/2a)
-(56/-4) = 14
width = 14 ft.
length = 56 - 2(14) = 28ft.
14*28 = 392 sq. ft.
The population of the country in 1990 is 249.5 million
<u>Step-by-step explanation</u>:
- Let 'x' be the population in 1990.
- The population in 2015 is 321.9 million.
The increase in x by 29% = 321.9
10^6
(since x is 100% and increase of 29% will be 129%)
129% of x = 321.910^6
1.29x = 321.910^6
x = 321.910^6/1.29
x = 249.510^6
x = 249.5 million.
∴ The population of the country in 1990 is 249.5 million
∵h = -16t + 541
So, after 2 seconds ⇒⇒⇒ t =2
substituting in the equation of h
∴ h = -16*2 + 541 = 509 feet
Answer:
i will explain :)
Step-by-step explanation:
there are three people. a grandfather, a father, and a son. the grandfather is the father of the father, and the father is the father of the son (if that makes any sense). the father is the son of the grandfather, and son is the son of the father. so technically while there are 2 sons and 2 fathers, there are still three people. :)
