John is constructing a triangle with two sides 5cm and 7 cm and the included angle is 70°. first, john draws a 5cm segment on his paper. he is not sure how to construct the 70° angle. what should he do? a) using a compass, draw a 7 cm circle. b) since 70° is less than 90°, just make sure to draw an acute angle. c) using a straightedge, measure a 7 cm segment from an endpoint of the 5 cm segment. d) using a protractor, measure a 70° angle from the endpoint of the 5 cm segment.

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
