Answer:
A. x > 13
Step-by-step explanation:
x-3>10
x>10+3
x>13
Answer:
C. f(-1) =12
Step-by-step explanation:
f(x)= 3x^2+9
Let x=-1
f(-1) = 3(-1)^2 +9
= 3(1)+9
= 3+9
= 12
f(-1) =12
Exact value of x will be 8 x sin(60)
Exact value of sin 60 = √3/2
So √3/2 x 8= 8 √3/2
Can be simplified to 4 √3
4/16 in simplest form is 1/4 because 4 goes into 4 1 time and 4 goes into 16 4 times
