17. in a turbine, a device used for mixing, the power required depends on the size and shape of the impeller. in the lab, we have collected the following data: 1 diameter (d) [ft] 0.5 0.75 1.5 2 2.25 2.5 2.75 power (p) [hp] 0.004 0.04 0.13 0.65 3 8 18 22 a. create a proper plot of the power (p, ordinate) versus the diameter (d) assuming the data are experimental. b. use polyfit to determine a power relationship for the data set and graph the resulting trendline along with the experimental data.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.

answer: 800
