We are given the arithmetic series 2, 1 3/5, 1 1/5.. In this case, the arithmetic difference is -2/5 by taking the difference of 2 and 1 3/5 and 1 3/5 and 1/5. The general formula of arithmetic sequence is an = a1 + d*(n-1). Substituting, an = 2 -2/5*(n-1). a25 hence is equal to a25 = 2-2/5*(25-1) = -38/5
Answer:
1 1/2 cups
Step-by-step explanation:
2/3 cup of almonds = 4 cups of trail mix
4 cups of trail mix = 2/3 cup of almond
4 cups of trail mix = 2/3 cup of almond
1 cup of trail mix = 2/3 ÷ 4 = 1/6 cup of almond
1 cup of trail mix = 1/6 cup of almond
9 cups of trail mix = 1/6 x 9 = 3/2 cup of almond
3/2 cups = 1 1/2 cups
Answer: 5 cos x
<u>Step-by-step explanation:</u>
y = sin x is y = cos x shifted to the right π/2 units.
y = 5 sin (x + π/2) is a shift to the left π/2 units (which results in cos x) and . an amplitude of 5.
--> y = 5 cos x
Answer:
It helps you know if the answer is reasonable because when you do the work and get your answer, you can check if it is close to your estimate, and if it is, it is most likely correct. On the other hand if it is not close to the estimate it is most likely wrong, unless you estimated incorrectly.
Step-by-step explanation:
No it is not a function, because a function cannot have more than one output per input. When x=-3, there are two solutions shown: (-3,2) and (-3,3), therefore it cannot be a function.
