sin 3 x = sin ( 3 x + 2 π ) = sin [ 3 ( x + 2 π/ 3 ) ] = sin 3 x
This means "after the arc rotating three time of ( x + ( 2 π /3 ) ) , sin 3x comes back to its initial value"
So, the period of sin 3x is 2 π /3 .
Answer:
Option B can be used to find the area of the face of the lamp shade in square inches
Step-by-step explanation:
We know that the area of the Trapezoid is
Area
where
a and b are the parallel sides
h is the height
Substituting the values from the figure
Answer:
Area of a triangle equals 1/2 Bh
base = 2.5 height = 5
2.5 x 5 = 12.5/2 = 6.25
since there are 4 sides you multiply by 4
6.25 x 4 = 25
Now to do the bottom you multiply 2.5 x 2.5 = 6.25
6.25 + 25 = 31.25<----ANSWER
Answer:
3/2
Step-by-step explanation:
to divide fractions you just have to multiply them by the reciprocal.
so, instead of 3/4 divided by 1/2
it's changed to 3/4 * 2/1
then you just multiply the numerators together and the denominators together
3*2/4*1
6/4
3/2
3/2
Goodluck with your schoolwork/homework.

Chris will solve his problem by dividing because using division can tell you a missing factor, and vice versa. 10 / 10 = 1, so 1 is the missing factor. Then Chris can multiply: 10 X 1 = 10. So, Chris will divide, then multiply.
