Bernardo needs to find the dimensions of his king-size mattress set so he can build a new bed frame. He knows the area of the bottom of the mattress set is 42 square feet and its length is 7 feet. Which other measurement does he need to know in order to build the bed frame? the perimeter of the mattress
the volume of the mattress
the width of the mattress
the area of the side of the mattress

F(x) = x2 − 9, and g(x) = x − 3 f(x) = x2 − 4x + 3, and g(x) = x − 3 f(x) = x2 + 4x − 5, and g(x) = x − 1 f(x) = x2 − 16, and g(x) = x − 4 h(x) = x + 5 arrowright h(x) = x + 3 arrowright h(x) = x + 4 arrowright h(x) = x − 1 arrowright

At the olympic games, many events have several rounds of competition. one of these events is the men's 100-meter backstroke. the upper dot plot shows the times (in seconds) of the top 8 finishers in the final round of the 2012 olympics. the lower dot plot shows the times of the same 8 swimmers, but in the semifinal round. which pieces of information can be gathered from these dot plots? (remember that lower swim times are faster.) choose all answers that apply: a: the swimmers had faster times on average in the final round. b: the times in the final round vary noticeably more than the times in the semifinal round. c: none of the above.

F(x) = 1/x g(x)=x-4 can you evaluate (g*f)(0) ? why or why not?
