Anna created the poster shown below: a rectangle is shown. the length of the rectangle is labeled as length equal to 36 cm, and the width is labeled as width equal to 16 cm. what would be the dimensions of the poster at fraction 1 over 4 times its current size? (5 points) length = 9 cm, width = 4 cm length = 144 cm, width = 64 cm length = 32 cm, width = 12 cm length = 40 cm, width = 20 cm

The function ƒ is defined by ƒ(x) = (x + 3)(x + 1). the graph of ƒ in the xy-plane is a parabola. which interval contains the x-coordinate of the vertex of the graph of ƒ?

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
