Subtract the average from the sales to get the deviation.
Aug. 1700 - 1412.50 = 287.50
Sept. 1125 - 1412.50 = -287.50
Oct. 1850 - 1412.50 = 437.50
Nov. 1500 - 1412.50 = 87.50
Dec. 1050 - 1412.50 = -362.50
Answer + Step-by-step explanation:
<u>24 + 7 and 9×(24+7)</u>
31 and 9 x (31)
31 and 279
the number is multiplied by 9
<u>12 - 7 and 4x(12-7)</u>
5 and 4 x (5)
5 and 20
the number is multiplied by 4
<u>3×(21 + 4) and 21 + 4</u>
3 x (25) and 25
75 and 25
the number is multiplied by 3
making the left side 3 times larger
<u>40 × 5 and 40 × 20</u>
200 and 800
To check the decay rate, we need to check the variation in y-axis.
Since our interval is
![-2We need to evaluate both function at those limits.At x = -2, we have a value of 4 for both of them, at x = 0 we have 1 for the exponential function and 0 to the quadratic function. Let's call the exponential f(x), and the quadratic g(x).[tex]\begin{gathered} f(-2)=g(-2)=4 \\ f(0)=1 \\ g(0)=0 \end{gathered}](https://tex.z-dn.net/?f=-2We%20need%20to%20evaluate%20both%20function%20at%20those%20limits.%3Cp%3E%3C%2Fp%3E%3Cp%3EAt%20x%20%3D%20-2%2C%20we%20have%20a%20value%20of%204%20for%20both%20of%20them%2C%20at%20x%20%3D%200%20we%20have%201%20for%20the%20exponential%20function%20and%200%20to%20the%20quadratic%20function.%20Let%27s%20call%20the%20exponential%20f%28x%29%2C%20and%20the%20quadratic%20g%28x%29.%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%5Btex%5D%5Cbegin%7Bgathered%7D%20f%28-2%29%3Dg%28-2%29%3D4%20%5C%5C%20f%280%29%3D1%20%5C%5C%20g%280%29%3D0%20%5Cend%7Bgathered%7D)
To compare the decay rates we need to check the variation on the y-axis of both functions.
Now, we calculate their ratio to find how they compare:
This tell us that the exponential function decays at three-fourths the rate of the quadratic function.
And this is the fourth option.
Hi,
The answer is 3/2 or 4
How I got my answer:
Just think that (2x+3) OR (x-4) has to be 0.
<span>
Than you can find it out with a simple +/- calculation. </span>
<span> 2x+3=0 x-4=0
x=-3/2 or 4</span>Hope this helps you.
