Answer:
y = 5
Step-by-step explanation:
That "+5" elevates the graph of this cosine function 5 units above the x axis, and thus the "midline" you wanted is y = 5.
The answer is D. When flipping a coin, the probability of getting tails does not change no matter how many times you flip the coin. It will always be 1/2.
The solution is subtract4.7x on both sides. Then you get -2.2x=7.7. Divide 7.7 by -2.2 and you get x= -3.5
It should be answer B. With 0.0321 there is a zero both before and after the decimal, while answer A only has one before the decimal.
