The last one is my favorite
C. f(x) = – 2 cos 6x + 1
Start by determining the amplitude. Since we've deduced the amplitude is 2, the equation can include either a positive or negative 2 (since amplitude measures absolute value).
Next is the period. The equation for period P is P = (2pi)/b. If P is pi/3, then
pi/3 = (2pi)/b. Thus your b value should be 6.
Finally, the midline would be given by + 1 since adding a unit shifts the function upwards. This means that instead of the highest y value being 2 and the lowest -2, instead you'd have values of 3 and -1.
(3 – 1)/2 = 1 (midpoint theory).
Answer:
I think this is a probability problem.
Step-by-step explanation:
201*0.9 the divide by 179??
Answer:
Your answer would be:
Since 6 is in the tenths places, the value of the digit is 0.6
Hope this helps Buddy!

Answer:
I can tell you the first one and you can figure it out from there. 70 is 40% persent of what number? Well, we can chop 40% to 20% and chop 70 in half and we get 35. So 35 = 20% So we multiply 35 by five, and get 175. So 70 is 40% of 175.
