On the top problem: Angle A and Angle B are a right angle so it equals 90 degrees. If Angle B is 50 degrees that makes Angle A 40 degrees. Angle A and Angle C is a straight line and equals 180 degrees so if Angle A equals 40 degrees that means Angle C equals 140 degrees.
A relation is (also) a function if every input x is mapped to a unique output y.
In terms of graphical representation, this implies that a graph represents a function if there doesn't exist a vertical line that intersects the graph more than once. So:
- The first graph is exactly a vertical line, so it's not a function.
- The second graph represents the function y=x, so it's a function: you can see that every possible vertical line crosses the graph only once.
- The third graph is not a function, because you can draw vertical lines that cross the graph twice.
- Similarly, in the fourth graph you can draw vertical lines that cross the graph twice
- The fifth graph is a function, because every vertical line crosses the graph once
- The last graph is a function, although discontinuous, for the same reason.
Answer:
8
Step-by-step Explanation:
Step 1. Divide 1200 by 300:
1200 ÷ 300 = 4
Step 2. Multiply 4 by 2:
4 * 2 = 8
20,000,000 is the answer fren
Answer:
x^8
Step-by-step explanation:
(x^4)^2
~Apply power rule [ (a^b)^c = a^bc ]
x^4(2)
~Simplify
x^8
Best of Luck!
