(05.03 MC) Part A: Explain why the x-coordinates of the points where the graphs of the
equations y = 4^-X and y = 2^x +3 intersect are the solutions of the equation 4^-X =
2^X+3. (4 points)
Part B: Make tables to find the solution to 4^-x= 2^X +3. Take the integer values of
x between -3 and 3. (4 points)
Part C: How can you solve the equation 4^-x= 2^x+3 graphically? (2 points)

Geometry in the diagram, ∠abc is a right angle. ∠dbc = 30°27'40". find the measure of ∠abd.

Acompany produces packets of soap powder labeled “giant size 32 ounces.” the actual weight of soap powder in such a box has a normal distribution with a mean of 33 oz and a standard deviation of 0.7 oz. to avoid having dissatisfied customers, the company says a box of soap is considered underweight if it weighs less than 32 oz. to avoid losing money, it labels the top 5% (the heaviest 5%) overweight. how heavy does a box have to be for it to be labeled overweight?
