(8+10 points) suppose in → z and wr →w. prove the following (a) zn+wn z+w (b) z wn → zw. (hint: try to imitate the proof of the case of functions that was proved in class.) (10 points) find the modulus and all arguments of -v3+i

What is the slope of the line (-7,2) (4,6)

Can someone show me step by step how to do this?

The weight of 46 new patients of a clinic from the year 2018 are recorded and listed below. construct a frequency distribution, using 7 classes. then, draw a histogram, a frequency polygon, and an ogive for the data, using the relative information from the frequency table for each of the graphs. describe the shape of the histogram. data set: 130 192 145 97 100 122 210 132 107 95 210 128 193 208 118 196 130 178 187 240 90 126 98 194 115 212 110 225 187 133 220 218 110 104 201 120 183 124 261 270 108 160 203 210 191 180 1) complete the frequency distribution table below (add as many rows as needed): - class limits - class boundaries - midpoint - frequency - cumulative frequency 2) histogram 3) frequency polygon 4) ogive
