From the table below, determine whether the data shows an exponential function. Explain why or why not. a.
х 3 2 1
-1
у 8 2 0.5 0.125
No; the domain values are at regular intervals and the range values have a common factor
0.25.
b. No; the domain values are not at regular intervals although the range values have a common
factor.
Yes; the domain values are at regular intervals and the range values have a common factor 4.
d. Yes; the domain values are at regular intervals and the range values have a common factor
0.25.
C.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
