Answer:
Option (A) and (E)
Step-by-step explanation:
Characteristics of the quadratic function representing the path of a whale as it surfaces for air is,
y = -4x²
1). Since domain of the given function will be all real number x until ocean hits the shore on both the sides of the path.
2). Range of the function will be the value of y from the bottom of the ocean to the surface.
3). Whale will touch the surface of the ocean at one point only.
4). Function 'f' will increase initially upto the surface of the ocean and then it will decrease.
5). Point where the hale touches the surface will be maximum.
Therefore, Options (A) and (E) will be the correct options.
Answer:
78.6m of fencing
That would cost $982.50
Step-by-step explanation:
Perimeter: 2(22.7)+2(16.6)=P
P = 78.6
Cost: 78.6*12.50
C = 982.50
We assume you mean

This is solved by writing 16 as a power of 4 and equating exponents.

2 = 3x - 7 . . . . . equate exponents
9 = 3x . . . . . add 7
3 = x . . . . . divide by 3
The solution is x = 3.
