There are 6 different singers who each sing two songs out of a set of 12 different songs. this month singer a sings songs 1 and 2, b sings 3 and 4, c sings 5 and 6, d sings 7 and 8, e sings 9 and 10, and singer f sings songs 11 and 12.find the number of possible assignments next month of two songs to various singers (so that all songs are sung)in which each singer sings at least one different song from the two songs he/she sang this month.

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
