There exists a trigonometric identity which states that,
sin (A - B) = sin A cos B - cos A sin B
This is very similar to the given expression with A equal to 57° and B equal to 13°. The simplified form of the angle is,
sin (57° - 13°) = sin 44°
P(blue) is 23/82 the sum is 82 and there is 23 blue balls
Answer:
The center is (0,0) and the radius is 4
Step-by-step explanation:
x^2+y^2=16.
The equation of a circle can be written in the form
(x-h)^2+(y-k)^2=r^2 where ( h,k) is the center and r is the radius
(x-0)^2+(y-0)^2=4^2
The center is (0,0) and the radius is 4
Answer: A
Step-by-step explanation:
because i did a quiz with the same and i got it right
Answer:
we use distributive property.
Step-by-step explanation:
for example:
4(5x+7)=
4x5x=20x
4x7=28
so the answer is:
20x+28
hope this helps : )
