You have the following expression given in the problem:
f(x) = x³ – 2x²<span> – x + 2
Therefore, to find the roots, you must apply the proccedure shown below:
1. You have:
0 </span><span>= x3 – 2x2 – x + 2
2. Then, when you factor, you obtain:
(x-2)(x-1)(x+1)=0
3. Therefore, you have that the roots are the following:
x1=-1
x2=1
x3=2</span>
Answer:
The cat is 2/3 feet tall
Step-by-step explanation:

1ft shadow = 2/3 ft tall
You are given the number of bagels sold daily for bakeries A and B and are shown in the table above. Based on the above data, it is better to describe the centers of distribution in terms of the mean than the median. This is because all of the data from bakery A and B have values that are near the average and no data sample have possible outliers. For instance,
bakery A
mean (A) = [<span>53 + 34 + 52 + 40 + 50 + 36 + 48 + 38]/8 = 43.88
Bakery B
mean (B) = [</span>53 + 41 + 47 + 44 + 55 + 40 + 51 + 39]/8 = 46.25
Even if bakery A and B has the 38 and 39 as the lowest data respectively, they are still near the average data.
