Answer:
Step-by-step explanation:
Note that 20 (an approximation for 205) less 4 (an approx. for 431) comes out to 16.
This tells us that the proper placement of the decimals is
20.50
- 4.31
----------
and this comes out to 16.19.
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
5(1.60+0.80)
(8+4)
12
Therefore Michelle spends 12 dollars in 5 days
So,
1. Tawni swam a 50-m Freestyle in 40.8 secs.
2. Pepita swam a 100-m Butterfly in 60.2 secs.
3. Susana swam a 200-m Medley in 112.4 secs.
Manipulate the distances so that they are the same.
Tawni would swim a 200-m in 163.2 secs.
Pepita would swim a 200-m in 120.4 secs.
Susana woulld swim a 200-m in 112.4 secs.
Susana swam the fastest.
