If the value is 100% of ' v ' today and it decreases 8% in a year,
then the value will be 92% of ' v ' 1 year later. That's 0.92v .
First, simplify the expression of the function 
highlighting the perfect square:
Then find the vertwx of parabola. When x=2, f(2)=2 and the coordinates of the vertex are (2,2). The axis of symmetry passes through the vertex and is parallel to the y-axis. Therefore, its equation is x=2 (see attached graph for details).
Answer: x=2.
Let c be children and a adults.
3.5c + 7a = 1771 (the total revenue is equal to the amounts made off of people)
c + a = 331 (total number of people)
The second formula becomes a = 331 - c. This can be substituted into the first formula.
3.5c + 7(331 - c) = 1771 = 7*331 - 3.5c = 1771. 7*331 = 2317, so 3.5c = 2317 - 1771 = 546.
546/3.5 = 156 = c (number of children).
c + a = 156 + a = 331 => a = 331 - 156 = 175 (number of adults).
There are 156 children and 175 adults
Answer:
A) Three times x to the second power added to two times y which is added to a half.
B) Six times x plus two multiplied by y added to one by two

Answer:
≈40.25 Feet
Step-by-step explanation:
The diagnal length of the orchard is the hypotenuse of the triangal with side lengths of 36 and 18.
Therefore, to calculate that, set the hypotenuse as x.
36²+18²=x²
√1620≈ 40.25yards
