a toy store advertises a sale on a popular children's game during the month of october. the number sold, n, is a function of the amount spent on advertising: where x is in dollars.
22. what is the meaning of the statement f(1000)=50?
23. assume that f(1000)=50 , and it's also true that the cost to the consumer of each item is $5, did the retailer make wise use of the store's advertising budget? explain your thinking.

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
