Answer: Drop down 1: 13
Drop down 2: a_n-1_-9
Step-by-step explanation:
To draw the region that represents the solution of the inequality you have to:
1. draw dashed vertical line (dashed because of sign of inequality is <, doesn't include notion equal to);
2. shade the region that determines all points on the coordinate plane that have x-coordinate less than 36.
The attached diagram represents the solution set for the given inequality.
Answer:
The figure is wrong beacuase
The total angle of triangle is 360
It si giben that one angle is 280
And the other is right angle
And when we summ it up it forms 370
which is not forms a circle
In place of 280 it should be 270
Answer:
option d
Step-by-step explanation:
AB = C
<em>Step 1: Multiply row 1 of matrix B by column 1, 2 and 3 of matrix A to get first column of C</em>
(2x-2)+(3x5)+(-5x-1) (2x-4)+(3x1)+(-5x-3) (2x2)+(3x5)+(-5x-4)
= (-4+15-5 -8+3+15 4+15+20)
= (16 10 39)
<em>Step 2: Multiply row 2 of matrix B by column 1, 2 and 3 of matrix A to get second column of C</em>
(5x-2)+(-4x5)+(2x-1) (5x-4)+(-4x1)+(2x-3) (5x2)+(-4x5)+(2x-4)
= (-10-20-2 -20-4-6 10-20-8)
= (-32 -30 -18)
<em>Step 3: Multiply row 3 of matrix B by column 1, 2 and 3 of matrix A to get third column of C</em>
(-1x-2)+(-1x5)+(3x-1) (-1x-4)+(-1x1)+(3x-3) (-1x2)+(-1x5)+(3x-4)
= (2-5-3 4-1-9 -2-5-12)
= (-6 -6 -19)
<em>Step 4: Form the whole matrix</em>
(16 10 39)
(-32 -30 -18 )
(-6 -6 -19 )
Therefore, option d is correct.
