Answer:
g(0) = -8
Step-by-step explanation:
When you plug in a zero for the x the equation will look like
g(0) = -2(0) - 8
-2 times 0 = 0 so g(0) = -8

16 will go where the question mark is located
So 3/6 = 8/16
Think of it like this: if you had three slices of pizza out of 6 total, then you had half the pizza. The same goes for if you had 8 slices out of 16 total
You can use the cross multiplication rule to find x
3/6 = 8/x
3*x = 6*8
3x = 48
3x/3 = 48/3
x = 16
The teacher has to take 10 questions at a time from 12 questions.
Total ways = 12C10 = 12!/(10!)(12-10)! = 12 x 11 / 2 = 66
The teacher can make 66 different exams
Answer:
Step-by-step explanation:
We have to express the given radical using imaginary unit.
We know that, imaginary unit:
We may solve the radical as:
