Nr. Norman wonders how many quizzes and tests he graded for his two eighth grade classes ast year. His eighth graders took a Quizzes and tests throughout the school year. He had 24
students in the first class and 26 students in the second class.
Pick all the expressions that represent how many eighth grade quizzes and tests Mr. Norman
249 +240 +269 + 260
500 + 50
24(+1) + 26(+)

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
