17. A 13-foot ladder is leaning against a vertical wall. If the
bottom of the ladder is being pulled away from the wall
at the rate of 2 feet per second, how fast is the area of
the triangle formed by the wall, the ground, and the ladder
changing at the instant the bottom of the ladder is 12 feet
from the wall?



ANSWER: -119/5 feet squared per second




19. A tank contains 1000 cubic feet of natural gas at a pressure of 5 pounds per square inch. Find the rate of change
of the volume if the pressure decreases at a rate of 0.05
pounds per square inch per hour. (Assume Boyle’s law:
pressure × volume = constant.)

ANSWER: 10 feet cubed per hour

If they exist why can we not see them? Is it because light requires gravitationl filelds and elromagnetic fields in order to be able to transverse space and the void that these universes exist in has no such fields? Or could it be that they are so far distant that light from them has not yet reached us? The big bang theory states that time and space came into being at that instant. Do you agree that space contains gravitational and eltromagnetic fields because of the condensation of energy into matter and the activity of this matter generated these fields? Is it not logical to believe that at one point there was absolutely nothing in existance and something came into being from that nothingness? If not, how else could it have been?

I am taking Geometry for my summer credit and need help understanding vocabulary so if you could simplyfy that would help
here is what i got

Median-of a triangle is a segment from the vertx tothe midpoint of the opposite side

altitude-perpendicular segment from a vertex to the opposite side or to the line that contains the opposite side

centroid of a a triangle- point always inside the triangle point of concurrency if the medians of a triangle

orthocenter-lines containing the altitides are concurrent and intersect at a point

perpendicular bisector-is a line that is perpendicular to a side of the triangle ar the midpoint of the side

circumcenter-point of concurrency of the perpendicular bisectors of a triangle

incenter of a triangle-point of concurrency of the angle bisector

reminder: if you can simplyfy these definitions or make them clearer in any way that would be a great help thank you

I need a formula using polar form i.e. (r1, theta 1) and (r2, theta 2). The more simplified the formula is the better :)
oh and heres a trig identity that may be useful:
cos(theta 1)cos(theta 2) + sin(theta 1)sin(theta 2)= cos(theta1-theta2)

My state requires all techs to be certified and registered with the state board before working so I did all that back in March and started working at Walgreens at the end of May. I didn't have any work experience but I needed a job that I could support myself with. They offered me $10.75/hr promising full time(30-40 hr). Problem: The only people getting full time are the Sr Techs and the Pharmacists. I've been fighting to get my full time in b/c I need it. They promise I'll get my hours when fall starts b/c it gets busy but one of the girls who started off as full time too is only getting 14 hr next week even after talking to the store manager 4 times! I'm starting college in the fall and wondering if I'm cut out for the retail setting.

So, techs, what're the big differences they don't tell you about between retail and hospital?
