We have
We start by calculating square root:
We can rewrite 4 in base of 2:
Now we can calculate this by using rule of same base and different exponent:
Answer:
Step-by-step explanation:
B
its B
Answer:
<u><em>Similarity:</em></u>
In Both cosine and sine graphs, a positive and negative number vertically flips the graph and tells whether the graph starts at maximum (positive) or minimum (negative).
<u><em>Difference:</em></u>
The difference between the sine and the cosine graph is the point where they start.
The graph of positive cosine starts at the maximum while that of the negative cosine starts at the minimum.
The graph of a positive sine starts at the middle, goes up and then down while that of the negative sine starts at the middle goes down and then up.
Answer:
5,000 meters * 1 kilometer / 1,000 meters = 5 kilometers answer is B
Step-by-step explanation:
5cos2(x + 45) - 7
The period for cos = 2pi/k
The k = 2 so the period = pi
The phase shift is 45 degrees to the left.
