Dishwashers are on sale for 25% off the original price ( d ), which can be expressed with the function p ( d ) = 0.75d. local taxes are an additional 14% of the discounted price, which can be expressed with the function c ( p ) = 1.14p. using this information, which of the following represents the final price of a dishwasher with the discount and taxes applied?
a. c ( p ) ⋅ p ( d ) = 0.855pd
b. c ( p ) + p ( d ) = 1.89d
c. c [ p ( d ) ] = 0.855d
d. d [ c ( p ) ] = 1.89p

the answer is

option c.

c[p(d)] = 0.855d

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
