52 inches - 12 inches = 40 inches
amplitude: a = 40 inches / 2 = 20
<span>f(x)=20cos(bx)+c</span>
the value of c is 32... since the centre of the has been moved up 32 units
the minimum amplitude = 32 - 20 = 12
the maximum amplitude = 32 + 20 = 52
<span>f(x)=20cos(bx)+32</span><span>
if the curve takes 6 1/4 hours from low to high tides (9:15 am to 3:30 pm) then it will take 12 1/2 hours to complete a full cycle.
adjust the period by converting 12 1/2 hours to an angle measure.
360</span>°/12 = 30°
30° / 12 = 15°
12 1/2 = 360° + 15° = 375°
f(x) = 20 cos(375°) + 32
f(x) = 20 * 0.97 + 32
f(x) = 19.4 + 32
f(x) = 51.4
Answer:
9.2 ounce
Step-by-step explanation:
To do this, we divide $12 by 16 ounces, because there are 16 ounces in a pound:
12/16 = 0.75
Now, we need to find how many ounces can be bought for $4.80. To do this, we divide 6.90 by 0.75
=9.2 ounce
Answer:
2 dollars.
Step-by-step explanation:
She went 8 times. It costs 1 quarter.
4 quarters = 1 dollar, so 8 quarters = 2 dollars.
