The graph of this sinasoid wave is B) f(x) = 3cos(x) + 3
We can tell this for two reasons. Firstly, the multiplier in the beginning is always equal to half of the height of the graph. Since the graph goes as high at 6 and as low as 0, we know the overall height is 6. Half of that is 3. This means that we have a 3 for the multiplier.
Next, we can decide between sin and cos by determining that it starts up and ends down. Sin starts moving up at the beginning and cos moves up at the beginning. Therefore, it must be the cos.
The reciprocal of 1/10 is 10/1 or 10. The reciprocal of 16 is 1/16. Basically to make it easier think of flipping or switching the numerator and denominator. Hope this was helpful.
Answer:
50%
Step-by-step explanation:
Enlarging it in the ratio 2:3 means dividing it by 2 and multiplying it by 3.
Lest's pretend the original size was 100 in. 100/2x3=150
So in this case we enlarged it by 50 in. which is 50% of 100.
So, the enlargement as a percentage is 50%
