Answer:

View the explanation

Step-by-step explanation:

The sine of an angle is equal to the cosine of that angle minus 90 degrees, and vice versa. Since 65=90-25, the cosine of 25 is equal to the sin of 65. If this is unclear please PM me or comment, and I can help more!

How would you describe the relationship between the real zeros and x-intercepts of the function y=log4(x-2)
notsponge [240]

Answer:

Step-by-step explanation:

First, look at y = log x.  The domain is (0, infinity).  The graph never touches the vertical axis, but is always to the right of it.  A real zero occurs at x = 1, as log 1 = 0 => (1, 0).  This point is also the x-intercept of y = log x.

Then look at y = log to the base 4 of x.  The domain is (0, infinity).  The graph never touches the vertical axis, but is always to the right of it.  Again, a real zero occurs at x = 1, as log to the base 4 of 1 = 0 => (1, 0).

Finally, look at y=log to the base 4 of (x-2).  The graph is the same as that of y = log to the base 4 of x, EXCEPT that the whole graph is translated 2 units to the right.  Thus, the graph crosses the x-axis at (3, 0), which is also the x-intercept.

How much is f(10) if f=x^2-2
dangina [55]

To find this value, simply substitute the number 10 in for x in your equation:

f(x) = x^2 - 2

f(10) = 10^2 - 2 = \boxed{98}

The answer is 98.
