Answer:
(1/3)^-2 = 9
Step-by-step explanation:
The negative power in this equation tells you to flip the fraction and get rid of the negative symbol. This becomes 3^2 which is 9.
Answer:
7
Step-by-step explanation:
Using the definition
n
= 
where n! = n(n - 1)(n - 2)..... 3 × 2 × 1
Then
7
=
=
← cancel out the multiples 6 ×5 × 4 × 3 × 2 × 1 , then
7
= 7
Answer:
AOC = 124°
Step-by-step explanation:
Angle on a straight line is 180°, therefore, the sum of the three angles shown is 180;
This can be written like so:
(3x + 94) + (x + 30) + (2x - 4) = 180
This equation can be solved to find x:
6x + 120 = 180
6x = 180 - 120
6x = 60
x = 10
AOC = 3(10) + 94
= 30 + 94
= 124
Answer:
X=0
Step-by-step explanation:
If you look at the graph and follow, the x axis to match up with y=12, then you will see that x is 0
