Answer:
C.
2 must be less than x if x is greater than 2, and x must be less than 4 if 4 is greater than x.
Answer:
(x -2)² +y² = 16
Step-by-step explanation:
The circle has its center at (h, k) = (2, 0), and has a radius of r = 4. The standard form equation is ...
(x -h)² +(y -k)² = r²
For the given values of (h, k) and r, this equation is ...
(x -2)² +y² = 16

Answer:
Step-by-step explanation:
The element at row i column j in the product is the dot-product of row i of the first matrix and column j of the second matrix. For example, row 2 column 1 of the product is ...
(row 2) · (column 1)
[3, -2, 4] · [2, 7, 1] = (3)(2) +(-2)(7) +(4)(1) = 6 -14 +4 = -4
The attachment shows the complete product matrix. It is convenient to let a spreadsheet or graphing calculator do the tedious repetitive arithmetic.
