If the equation is

then rewrite the equation as

Divide boths sides by 7:

Since
, we can factorize this as

Now solve for <em>x </em>:



where <em>n</em> is any integer.
If you meant sin(2<em>x</em>) instead, I'm not sure there's a simple way to get a solution...
Answer:
645.56
Step-by-step explanation:
50000/1000 13.37=673.50

-27.94
Answer:
3.5 Grams
Step-by-step
set 2grams/60lbs equal to xgrams/105
x representing the amount of medicine needed for a 105lb child
Then you divide 60 by 105.
60/105=1.75
Now you multiply 2 by 1.75.
2 x 1.75 = 3.5
3.5 is your answer because 105 is 1.75 times more lbs than 60lbs
meaning you would need 1.75 times the amount of 2grams
to determine the value of x, which is 3.5grams
Answer:
(-4,0) and (4,0)
Step-by-step explanation:
The x-intercepts occur for values of x where f(x) = 0.
f(x) = 0 when the nominator (
) = 0.
is a difference of squares,
so you can factor it as (x + 4)(x – 4)
When x = –4 or x = 4, the nominator is 0, and f(x) = 0
ANSWER:
A ) It also increases.
EXPLANATION:
When the measure of angle A increases im the trianes, the measure of angle A on line p also increases. This is angle A in the triangle and angle A on line p are equivalent to each other. Hence, if there is an increase to one of the angle As then there is also an increase to the other.
Therefore, the answer must be:
A ) It also increases.
