Use crout's method of lu factorization, without pivoting, to solve the system of equations given. when reporting your answer, convert to decimal form.
what is the value of l(2,2)? answer is 10
what is the value of u(2,3)? answer is 0.1
before solving for the unknown solution set x, an intermediate solution set, y, must be determined. in doing so, what is the value found for y(2)? answer is -1.3
what is the solution?
x=-2
y=-1.5
z=2
a=[-1 2 0; 4 2 1; 0.5 -2 0]
b= [-1; -9; 2]

(i really need ) read the story problem, and then answer the questions that follow. gordon works for a graphic design firm and is creating a label for a food truck vendor. the vendor specializes in finger food and wants to sell food in right conical containers so that they are easy for people to hold. to complete his label, gordon needs to collect several different measurements to ensure that the label he designs will fit the surface of the container. gordon has been told that the containers have a diameter of 4 inches and a height of 6 inches. part a: find the slant height of the cone. the slant height is the distance from the apex, or tip, to the base along the cone’s lateral surface. show your work. part b: find the measure of the angle formed between the base of the cone and a line segment that represents the slant height. part c: imagine two line segments where each represents a slant height of the cone. the segments are on opposite sides of the cone and meet at the apex. find the measurement of the angle formed between the line segments.

Which of the following is another way to express the difference between -5 and 8?

If its non of them tell me..valerie took a day-trip. she drove from her house for a while and took a coffee break. after her coffee break, she continued driving. after  2  hours of driving after her coffee break, her distance from her house was  210  miles. her average speed during the whole trip was  60  miles per hour. valerie created the equation  y−210=60(x−2)  to represent this situation, where  xx  represents the time in hours from her coffee break and  yy  represents the distance in miles from her house. which graph correctly represents valerie's distance from her house after her coffee break?
