Leo is constructing a tangent line from point q to circle p. what is his next step?

a. mark the point of intersection s of the segment created from the arcs and circle

r, and construct line rs.

b. mark the point of intersection s of circles r and p, and construct line qs.

c. construct arcs from point q that are greater than half the length of segment pq. d. construct a circle from point p that has a radius of p and the intersection of circles p and r.

In a coastal town, the humidity, measured in grams of water per kilogram of air, increases by 43% for every 1 degree celsius increase in temperature. a scientist observes that the humidity on monday morning is 5.75 grams per kilogram. he wants to know how much the temperature must increase for the humidity to reach at least 49.17 grams per kilogram. let t represent the increase in temperature, in degrees celsius, from monday morning's observation. write an inequality to represent the situation, and use it to determine the desired temperature increase.
