Answer:

  D)  undefined

Step-by-step explanation:

The tangent function is undefined for odd multiples of pi/2.

__

<em>Additional comment</em>

The terminal point on the unit circle of the ray at angle 3π/2 is (0, -1). The tangent is the ratio of the y-coordinate to the x-coordinate: y/x = -1/0. It is undefined at that point.

Between x = 2 and x = 3, which function has a smaller average rate of change than y = 2x ? A) y = 2 3 -x B) y = 4x - 1 C) y = 5x
xxTIMURxx [149]
The two points are (x, f(x)) and (x+h, f(x+h)).  To find the slope, the definition is the change in y over the change of x.  Does this sound familiar!!  Applying this definition we get the following formula:  and the points x<span>1 = 2 and x2 = 4.  Then in our general answer, we will replace x with x1 and h = x2 - x1.  Replacing these values in the formula yields  2(2) + (4 - 2) = 4 + 2 = 6.  Thus, the slope of the secant line connecting the two points of the function is 6. </span><span>Now using the same function as above, find the average rate of change between x1 = -1 and x2<span> = -3.  The answer is 2(-1) + ( -3 + 1) = -2 + -2 = -4.  This means that the secant line is going downhill or decreasing as you look at it from le</span></span>

How to find the domain and range of a function
Rasek [7]

Answer:

The domain of a function is the complete set of possible values of the independent variable. The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.

Step-by-step explanation:

When finding the domain, remember:

The denominator (bottom) of a fraction cannot be zero

The number under a square root sign must be positive in this section

The range is the resulting y-values we get after substituting all the possible x-values.

Kendra flips a fair coin two times. What is the probability that she will flip tails both times?
wolverine [178]

Answer: 1/4 or 25%

Step-by-step explanation:

The chance of flipping tails is 1/2, so you multiply 1/2*1/2 (for the 2 flips) to get 1/4 (1/2^2=1/4).

daser333 [38]

Answer:

$ 36.66 were take off the original price at Nike Outlet.

Step-by-step explanation:

The amount of money taken off the original price is obtained by subtracting actual price from original price. That is:

x = \frac{\$\,109.99}{1-0.25} - \$\,109.99

x = \$\,36.66

$ 36.66 were take off the original price at Nike Outlet.
