Answer:
∑ (n = 1 to 5) (2·(-4)^(n - 1))
S5 = 2·((-4)^5 - 1)/((-4) - 1) = 410
Answer:6.986
Step-by-step explanation:
To find the standard deviation of a set of data I find it easiest to make a chart. First you must find the mean of your data. In this case it is 476.85. Then you must subtract the mean from each data point, and square each number. Now you take your new set of data that has been squared and find the mean of these numbers. This is 48.8006. Lastly, take the square root of this number. In this case your standard deviation is 6.986.
Hello!
To find what percentage of 132 is 40, we must use a certain formula.
(40 ÷ 132) × 100 = 30.3
A N S W E R:
40 is 30.3% of 132.
The quadrants is tan⁻¹x restricted is A. Quadrants I and IV
To answer the question, we need to know what tan⁻¹x is.
<h3>What is tan⁻¹x?</h3>
tan⁻¹x is the inverse trigonometric function of tanx, which is the value of the angle for tanx.
<h3>Quadrant in which tan⁻¹x is restricted</h3>
To find the quadrants in which tan⁻¹x is restricted, we know that tanx lies in the range
-∞ ≤ tanx ≤ +∞ for -90° ≤ x ≤ 90°.
- Since the inverse function of tanx is x.
- tan⁻¹x lies between -90° and 90°. That is -90° ≤ tan⁻¹x ≤ 90°.
- Since 90° lies in first quadrant and -90° lies in the fourth quadrant
tan⁻¹x lies between quadrant I and IV
So, the quadrants is tan⁻¹x restricted is A. Quadrants I and IV
