Give a direct proof of the lemma to Theorem 4.14. That is, given any rectangle with vertices (a, c), (b, c), (b, d) and (a, d), parameterize the boundary and verify directly that dz = zdz = 0.

for me what is finding a good play list and going out because i can not lay down and relax so i usually go to a coffee shop. i also use the gum trick and this actually works. another advice is highlighting subjects it really does me remember certain things

step-by-step explanation:

m∠a is 90°

m∠b is 40°

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168

false

inverse variation is not exponential
