Answer:
B) A racquetball club has a tournament where each member plays every other member and represents the scores in a matrix.
Step-by-step explanation:
A square matrix is where the number of rows is equal to the number of columns like order 2x2, 3x3, 4x4, 5x5 etc.
Given options are:-
A) A shoe salesperson wants to use an augmented matrix to represent the quantity of children’s shoes and adult shoes sold at his store for two days.
It is 2x2 times 2x1 = 2x1 matrix.
B) A racquetball club has a tournament where each member plays every other member and represents the scores in a matrix.
It is 6x1 times 1x6 = 6x6 matrix.
C) A student wants to write a coefficient matrix representing a linear system with two equations and three unknowns.
It is 2x3 times 3x1 = 2x1 matrix
D) A teacher wants to write an augmented matrix representing a linear system with four equations and four unknowns.
It is 4x4 times 4x1 = 4x1 matrix.
Hence option B is correct.
Answer:
Step-by-step explanation:
y=x²+6x+5
=(x²+6x+(6/2)²)-(6/2)²+5
=(x+3)²-9+5
=(x+3)²-4
The axis of symmetry is x+3=0
or x=-3
when x=-3,f(x)=-4
vertex is (-3,-4)
Domain :-∞<x<∞
or (-∞,∞)
Range:[-4,∞)
Momentum= mass x velocity
3220kg m/s = 700g x 4.6 m/s
A regular polygon can be any shape with all equal side lengths and equal angle measurements.
So, yes. It can be a regular polygon.
Hope this helps! <3
We need to find the remainder- the sticker left over
Divide 23 stickers into 4 piles = 23/4= 5 stickers per pile and 3 stickers left over
D. She would have 3 stickers left over
