Hello! Congruent figures are those with the same size and shape. With that being said, if you look at the shapes correctly, here are your answers:
Quad 1 & 2: Not Congruent
Quad 1 & 3: Congruent
Quad 1 & 4: Congruent
Quad 2 & 3: Not Congruent
Quad 2 & 4: Not Congruent
Quad 3 & 4: Congruent
A hundredth is 0.01
A hundred is 100.
You look at the digital to the right of the 1, in the example above. If that digit is 5 or greater, round up, other round down.
In both cases, you will look at the 0, therefore you would round down.
1800 to the nearest hundredth is 1800.00.
1800 to the nearest hundred is 1800.
Answer:
9/2 [ cos(15x) + cos(3x) ]
Step-by-step explanation:
9cos(6x) . cos(9x) can be expressed as
= 9/2 * 2cos (6x) * cos(9x) next here we will apply the rule
2cosA . cosB = cos(A+B) + cos( A-B)
where A = 6x , B = 9x
hence : 9cos(6x) . cos(9x) expressed as a sum will be
= 9/2 * [cos( 6x+ 9x) + cos( 6x - 9x ) ]
= 9/2 [ cos (15x ) + cos(-3x) ]
the final sum = 9/2 [ cos(15x) + cos(3x) ]
