The cofactors of each entry in the first row of the matrix are
Ac_11 = -13
Ac_12 = 44
Ac_13 = 27
We have to determine the cofactors of each entry in the first row of the matrix.
Therefore the cofactors of each entry in the first row of the matrix are
Ac_11 = -13
Ac_12 = 44
Ac_13 = 27.
A set of numbers is arranged in rows and columns so as to form a rectangular array. The numbers are called the elements, or entries, of the matrix.
Machines had to find a way to cut themselves off from the truth in order to understand humans. Neo's sole purpose in the Matrix is to prevent machines from evolving into dinosaurs.

#SPJ4
∠A=36° ∠B=67° measures of a=8
in a Δ sum of all angles are 180
∠A+∠B+∠C=180
36+67+∠C=180
∠C=77
Now use law of sines
a/sinA=b/sinB=c/sinC
8/sin36=b/sin67
now u can find B and C
Slope-intercept form of a line:
y=mx+b
m=slope
We have this equation of a line:
y=2x+3
The slope of the line will be; m=2
Ohter line that is parallel to this line(y=2x+3) will have the same slope, therefore the slope will be: m=2
Point-slope form: we need a point (x₀,y₀) and the slope:
y-y₀=m(x-x₀).
We have thel point (-4,1) and the slope:
therefore:
y-1=2(x+4) (point-slope form)
y-1=2x+8
y=2x+8+1
y=2x+9 (slope-intercept form).
answer: the equation of the line that is parallel to this line y=2x+3 , is:
y=2x+9
Identity property!
Because the identity property for addition tells us that zero added to any number is the number itself. Zero is called the "additive identity." In this case, 0 is being added to 40.
Expand (x - 4)²
(x - 4) (x - 4) = x² - 4x - 4x + 16
x² - 8x +16
