Answer:
-cos(2x)
Step-by-step explanation:
I did trig last year and tutor a trig class this year :)
If it were a complete circle, its circumference would be
(π) x (diameter) = (π) x (2R) = 70 π inches .
Since it's only half of the circle, the length of the curved part is
70 π / 2 = 35 π = <em>109.9 inches</em> .
Answer:
It looks like the third one, C
Step-by-step explanation:
Every time c increases by 1, d increases by 2
That means the slope will be 1/2
That means the slope is positive
Which means that there can only be one answer, C
Its a
because you add 6x to the other side with the 42 which would look like 6x + 42
and divide by 2 on each side which equals
