How to find the range of f(x)=1/sinx, and how to know how to draw it
Anestetic [448]

Answer:

  see the attached for a graph

  the range is (-∞, 1] ∪ [1, ∞)

Step-by-step explanation:

You know the range of the sine function is [-1, 1], including zero. So, the minimum absolute value of 1/sin(x) will be 1/1 = 1, and it will go up from there (or down from -1) toward infinity. The vertical asymptotes will be where sin(x) = 0, at multiples of π.

To graph it by hand, you can pick a few points in any quadrant of the sine function and find their inverses. Plot those. You can take advantage of the symmetry about π/2 and about the origin. You can also take advantage of the periodicity.

A graph is attached.

Please help me with this math problem. Find the equation for the line below.
lora16 [44]

Answer:

y+2=3/4(x+5)

Step-by-step explanation:

The first step is to find the slope of the line. Between the two points, the line rises from a y value of -2 to a y value of 4, or a total rise of 6 units. It also goes to the right from an x value of -5 to an x value of 3, which is a total of 8 units. 6 units of rise over 8 units of run is a total slope of 6/8=3/4. Now, you can use the point slope form for either one of the points (I'll use the leftmost one).

y+2=3/4(x+5)

Hope this helps!

The population of camden, New Jersey has been decreasing by 0.12% a year on average. If this trend continues, and the population
Talja [164]
By the trend that is being given above, the population of New Jersey will only be 99.88% of the population from the previous year. It may be calculated through the following equation,
                               P(n) = P(0) x (1 - r)^n
Substituting the values from the given above,
                                  P(n) = 79,318 x (0.9988)^(2015 - 2006)
                                          = 78465.47
Thus, the population will approximately be 78,466.
