Solve the exponential equation. Round to three decimal places when necessary.150 - (1.75)x = 0
A. 8.954 B. 9.966 C. 7.72 D. 10.188
First, rewrite each equation in exponential form. Then, use a table of coordinates and the exponential form to graph the logarithmic function. Begin by selecting -2, -1, 0, 1 and 2 for y. Finally, based on your graph, describe the shape of a scatter plot that can be modeled by f(x) = log b x, 0 < b < 1.y = log1/7 x

Solve the problem.A student is told to work any 7 out of 10 questions on an exam. In how many different ways can he complete the exam? (The correctness of his answers has no bearing.)
A. 120 B. 10,000,000 C. 720 D. 21
Provide an appropriate response.Years ago, people used fountain pens. The ink was very "wet" and so a blotter was used to absorb "wet" ink left on the surface of the paper. Suppose you have a single sheet of graph paper and that you have just used your fountain pen to graph the one-to-one function f. Explain how, if the ink is "wet", you could now obtain the graph of f-1 using only your sheet of graph paper. (Hint: Fold the sheet of graph paper.)
