to get the equation of any straight line we simply need two points off of it, hmmm let's use the points in the picture below.
Answer:
see below
Step-by-step explanation:
The variables are listed top down in the variable vector in the same order as the coefficients are listed left-to-right in the equations. Each of the equations needs to have the variables listed in the same order.
Answer:
10
Step-by-step explanation:
Find the mean
9+12+10+15+15+15+10+x/8=12
divide 86+x/8=12
multiply both sides by 8
86+x=96
sub 86 from both sides
x=10

Step-by-step explanation:
For tan(405 degrees):
405° = 360° + 45° = 45° = 9π/4 = π/4
tanx = sinx/cosx
sin(π/4) = √2/2
cos(π/4) = √2/2
[√2/2] / [√2/2] = 1
<span>Therefore: tan(405°) = 1
