Use the quadratic formula to solve x^2-4x+3. Show your work. Then describe the solution
mars1129 [50]
Quadratic formula is x=(-b+-sqrt(b^2-4ac))/(2a)

a= 1, b=-4, and c=3

Therefore, x=(-(-4)+-sqrt((-4)^2-4(1)(3))/(2(1))

Solve for both the plus and minus equations; the answers will be the roots to the quadratic equation.

Suppose that a group of 10 students are to be assigned to four dorm rooms: a single, a double, a triple and a quad. How many way
Nesterboy [21]

Answer:

Total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200

Step-by-step explanation:

We have given number of students = 10

These 10 students are assigned to four dorm rooms a single, a double, a triple and a quad

So number of ways to assigned single student =^{10}C_1=\frac{10!}{1!9!}=10\\

Now left student = 10 -1 = 9

So number of ways to assigned double student =^{9}C_2=\frac{9!}{2!7!}=36

Now left student = 9-2 = 7

So number of ways to assigned triple student =^{7}C_3=\frac{7!}{2!4!}==70

Now left student = 7 - 3 = 4

So number of ways to assigned quad student =^{4}C_4=\frac{4!}{4!0!}=1

So total number of ways to select all sstudent to make assignment = 10×36×70×1 = 25200
