You begin publishing a newspaper for your town. Your revenue for x newspapers sold is given by f(x) = 1.4x
.Your profit p is $20 less than 70% of the revenue for
x newspapers sold.
a. Create a function to model this situation and
describe the transformation.
b. Find the profit for 180 newspaper sales.
C. How would your profits change if your revenue
function was Ax) = 2.4x?

Olivia uses the work below to determine 55% of 720 which explains the error in olivia’s solution

What is the frequency of the sinusoidal graph?

Given: ad¯¯¯¯¯ is an altitude. prove: ab2+ac2=cb2 right triangle a b c with right angle a. point d lies on side b c and segment a d is drawn. angle a d c is a right angle. drag and drop a reason into each box to correctly complete the two-column proof. statement reason ad¯¯¯¯¯ is an altitude, and ∠bac is a right angle. given ∠adb and ∠adc are right angles. definition of altitude ∠bac≅∠bda ? ∠bac≅∠adc ? ∠b≅∠b ? ∠c≅∠c reflexive property of congruence △abc∼△dba ? △abc∼△dac aa similarity postulate abbd=cbab ? ab2=(cb)(bd) cross multiply and simplify. acdc=cbac polygon similarity postulate ac2=(cb)(dc) cross multiply and simplify. ab2+ac2=ab2+(cb)(dc) addition property of equality ab2+ac2=(cb)(bd)+(cb)(dc) substitution property of equality ab2+ac2=(cb)(bd+dc) ? bd+dc=cb segment addition postulate ab2+ac2=cb2 substitution property of equality
