Answer:
a76 = 8 + (76-1)*6
= 8 + 75*6
= 8 + 450
= 458
the 76th term of the arithmetic sequence 8, 14, 20 is 458
b)Find the probability of selecting a number written in blue or selecting a number tat is multiple of 10. Write your answer as a fraction and completely simplify.
Factor:
5x^2 + 28x + 32 =======> Solution: ======> ( x + 4 ) ( 5x + 8 )
Steps: Factor
5x^2 + 28x + 32
Break the expressions into groups:
( 5x^2 + 20x ) + ( 8x + 32 )
Factor Out 5x^2 From 5x^2 + 20x ======> 5x( x + 4 )
Factor Out the 8 From 8x + 32 ========> 8 ( x + 4 )
= 5x (x + 4 ) + 8 ( x + 4 )
Factor Out Common term:
x + 4
Answer =====> Factor of; ==> 5x^2 + 28x + 32 ( x + 4 ) ( 5x + 8 )
Hope that helps!!!! : )
Answer:
Similarity:
In Both cosine and sine graphs, a positive and negative number vertically flips the graph and tells whether the graph starts at maximum (positive) or minimum (negative).
Difference:
The difference between the sine and the cosine graph is the point where they start.
The graph of positive cosine starts at the maximum while that of the negative cosine starts at the minimum.
The graph of a positive sine starts at the middle, goes up and then down while that of the negative sine starts at the middle goes down and then up.
