Now, assuming is a vertical parabola, so the squared variable is the "x", let's do some checking.
Answer:
Domain: all real numbers
Step-by-step explanation:
The domain of a function is the set of values that x can be replaced with.
In this function, x can be replaced by any real number, so the domain of the function is all real numbers.
44 peices are needed to surround the yard in fencing
Answer:
Step-by-step explanation:
The modelled equation, P = 20n - 1200 is written in the slope intercept form. The slope of the line is 20. The line cuts the vertical axis at - 1200
a) the p intercept is - 1200(cost of production)
b) at the p intercept, the number,
n = 0. It means that no watches are sold. Therefore,
If the company sells 0 watches, it will lose $1200
c) the n intercept is the point where the line cuts the x axis.
At the n intercept, P = 0
0 = 20n - 1200
20n = 1200
n = 1200/20
n = 60
d) if the company sells 60 watches, it will lose $0
4.9 = 0.7m |(*10)
4.9 * 10 = 0.7m * 10
49 = 7m |(:7)
49/7 = 7m/7
m = 7
