The second option is the answer
Sin63= 0.89
cos27= 0.89
tan57= 1.54
E is currently at (3,-2).
A scale dilation by a factor of 2 means that everything (both x and y coordinates) will be twice as big.
So multiply each coordinate by 2 and what do you get?
3^-1 divided by 3^4 =
when dividing exponents with the same base, subtract the exponents
3^(-1-4)
3^-5
a=-5
Answer a=-5
