Question 4 (1 point) A company finds that if it charges z dollars for a cell phone, it can expect to sell 1,000 – 22 phones. The company
uses the function - defined by "(=) = 2.(1,000 - 22) to model the expected revenue, in dollars, from selling cell
phones at zdollars each.
Use graphing technology to graph the function r. What do the s-intercepts mean in this situation?

whew you’re speaking a different language

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.  

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !

if i'm not wrong, i would say that the third angle has (72) because the three sides of all triangles have 180 degrees and if we subtract 180 - 62 - 40 = (72) / but i'm not sure about 40 yd.
