The manufacturer of a new product developed the following expression to predict the monthly profit, in thousands of dollars, from sales of t product when it is sold at a unit price of x dollars. -0.5x2 + 221 – 224 what is represented by the zero(s) of the expression? a. the unit price(s) when the profit is equal to 0 b. the unit price(s) when profit is greatest c. the profit when the unit price is equal to 0 od. the profit when the unit price is greatest reset next

A. The answer is our unit prices when our profit is 0

Step-by-step explanation:

The zeros are the x-intercepts, when the curve passes through the x-axis.

I'm going to call our function P

P(x)=-0.5x^2+221x-224 is equal to 0 (our profit is equal to 0) when x (the unit price is such and such)

The answer is our unit prices when our profit is 0

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

the answer is -1 for this question
