2 The pressure of the atmosphere is 14.7 lb/in2 at Earth's surface I decreases by about 20% for
each mile of altitude up to about 50 miles. Write an
equation that estimates the atmospheric pressure at
an altitude of + miles. Estimate the atmospheric
pressure at an attitude of 10 miles.

In the following diagram it is given that dec, ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2

Simplify. (-2)^-3 a. -8 b. -1/8 c. 1/8 d. 8
