How do you find all the roots of x^4 - 6x^3 + 11x2 - 2x - 10 = 0 given that ( 2-i ) is a root of f.

How far are you from the base of a tree 100 feet tall if the angle of elevation to the top of the tree is 30°?

The solution is: Distance= 100√3,

but what is the process to do it? thanks!

Given the standard form of a circle (x - h)^2 + (y - k)^2 = r^2, find the center and radious of the equation:

x^2 + y^2 - 10x - 12y - 8 = 0

There are two tubings (one transparent and one blue). Which do you insert the syringe in?

Thanks!!

or otherwise? Why?

I met a guy online and I've been thinking if I should meet him first by using Skype or if I should just go see him in person; he lives like an hour away so a face-to-face meeting is not complicated to arrange. However, I'm still confused about what would be better, what would you do?

How do you do this in Excel? Please I need to know it in order to do the others steps. Thank you very much!

In cell C7, enter a formula that will calculate the percent of Ice Cream Bars - Chocolate sales (in cell A:7) out of the total 2016 sales (in cell B:14). Make the reference to cell B14 an absolute reference. Change the format of the cell to percentage with no decimals, and then copy the formula down through cell C13.

I got stuck in this problem and I'm not sure how to finish it. I appreciate your help. Thanks!

A maternity hospital would like to give special treatment to babies in the lowest 3% or the highest 1% of birth weights, as they've discovered that these babies are often at risk. Birth weights in the U.S. are normally distributed with a mean of 3420 grams and a standard deviation of 495 grams. What are the specific birth weights that form the cut-offs for the lowest 3%( i.e., the 3rd percentile) and the highest 1% of newborns' weights?

1. Suppose a "probability experiment" consists of drawing a number at random from the integers between 1 and 10, inclusive. Then the "sample space" of possible results of this experiment is composed of the numbers {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. If "event A" is the result that the number drawn at random from this set is greater than 7 (x > 7), what is the complement of event A (that is, A')?

2. What is the probability of drawing a number from this set that's divisible by 3?

How would you rewrite these cliches so that the same thought is expressed in an unexpected manner?

1) Ugly as sin

2) Swear like a sailor
