Answer:

Below.

Step-by-step explanation:

(sine) sin=30=1/2

=cos [90-30]

Which means cos=60

Same as:

(cosine) cos=60=1/2 or Sin30=Cos 60=1/2

Hence, the answer is...

cos 60° = ½....

PLEASEEEE HELP FOR BRAINLIST!!!!!!!!!

Same thing as before!

First, we can get rid of d(x) simply by looking at it because we can tell it's linear (it's a straight line). If we look at the table, we can see a(x) is also linear because it has a steady rate of growth. b(x) and c(x) both represent exponential growth. The curved shape of b(x) shows us this is exponential growth, and the exponent in c(x) tells us it's also exponential.
