Answer:
The correct option is 4.
Step-by-step explanation:
The given function is
Where f(x) is height of the ball and x is the distance.
It is a polynomial function with degree 2. All polynomial functions are defined for all real numbers, therefore the mathematical domain of the function is all real numbers.
Factorize the given function.
Put f(x)=0 to find the x intercepts.
Equate each factor equal to 0.
Therefore at x=52 and -2, the graph of f(x) intersects x-axis. Before x=-2 and after x=52 the values of f(x) is negative. Height cannot be negative, therefore reasonable domain is lie between -2 to 52.
Distance cannot be negative, therefore the reasonable domain must be positive.
Therefore the reasonable domain is and option 4 is correct.
The location of the treasure on the treasure map is (b) (7.6,8.8)
The ratio is given as:
The coordinates of the rock and the tree are:
The x and y coordinates of the location of the treasure are:
So, we have:
Hence, the location of the treasure is (b) (7.6,8.8)

|x + 2| < 4
As neither x or 2 are negative, the bars do not matter and can be eliminated.
x + 2 < 4
Minus 2 from both sides, and because you subtracted, make sure to turn the 'less than' sign into a 'greater than' sign.
x > 2 is your answer
Answer:
You can hold 188.19 or a rounded 188 pounds per cubic feet
Step-by-step explanation:
First we need to find the area which is 271
I found this using the formula 2(WL+HL+HW)
If you can fit 271 square feet then you need to divide that by 4 to find cubic feet.
if you do this you get 67.75 cubic feet
next divide 67.75 by 0.36
you get 188.19
