Answer:
Any number that ends with a zero is divisible by ten
Answer:
10cos(5x)sin(10x) = 5[sin (15x) + sin (5x)]
Step-by-step explanation:
In this question, we are tasked with writing the product as a sum.
To do this, we shall be using the sum to product formula below;
cosαsinβ = 1/2[ sin(α + β) - sin(α - β)]
From the question, we can say α= 5x and β= 10x
Plugging these values into the equation, we have
10cos(5x)sin(10x) = (10) × 1/2[sin (5x + 10x) - sin(5x - 10x)]
= 5[sin (15x) - sin (-5x)]
We apply odd identity i.e sin(-x) = -sinx
Thus applying same to sin(-5x)
sin(-5x) = -sin(5x)
Thus;
5[sin (15x) - sin (-5x)] = 5[sin (15x) -(-sin(5x))]
= 5[sin (15x) + sin (5x)]
Hence, 10cos(5x)sin(10x) = 5[sin (15x) + sin (5x)]
Answer:
64,9
Step-by-step explanation:
From my understanding the pattern would be:
Every other number is the next consecutive odd number,
( 1, 3, 5, 7 ) are all of the consecutive odds. (So the next odd is 9. )
That when we get to the part of where we get every other number for the remaining numbers, if you multiply the next even number by itself (square it).
4, 16, and 36 ( they are all perfect squares. )
They are the perfect squares of ( 2, 4, and 6) . So it makes sense that ( 8 ) is the next even number and you would square that and get ( 64 )
I hope this makes sense!!
Answer:
1 1/2
Step-by-step explanation:
SO first convert into mixed
1 15/30
Now simplify
1 1/2
IF YOU DONT WANT MIX AND LEAVE AS IMPROPER
3/2
