Tides are cyclical phenomena caused by the gravitational pull of the sun and the moon. On a particular retaining wall, the ocean

generally reaches the 2.1 m mark at high tide. At low tide, the water reaches the 0.8 m mark. Assume that high tide occurs at 12:00 p.m. and at 12:00 a.m., and that low tide occurs at 6:00 p.m. and 6:00 a.m. What is the height of the water at 9:30 a.m.?

1.5581 m

Step-by-step explanation:

For every cycle, it takes 6 hours to get from a high to low tide and another 6 hours back to high tide.

The change in the height of the tide in meters is;

2.1 – 0. 8 = 1.3 m

Therefore for every 6 hours, the tides shift by 1.3 meters. The average change is;

1.3 m / 6 hr

= 0.217 m / hr

= 0.00361 m / min

At 9.30 am, the tides are rising from low tides of 6.00 am

9.30 – 6.00 = 3.30

3hrs 30 min

= 210 min

The rise of the tide at this time is by;

0.00361 * 210

= 0.7581 m

The height of the tides will therefore be;

0.8 m + 0.7581m

= 1.5581 m

Korolek [52]

Answer:

30 plants.

Step-by-step explanation:

Elizabeth has 1 and 7/10 as many plants as Rosalie, so she has more plants than her, since the fraction is greater than one. So that means you need to take the number of plants Elizabeth has and divide it by the fraction.

51 / (1 7/10) = 30

To do this, remember to make both sides into a mixed number fraction, flip the second fraction, and then multiply them together. So 1 and 7/10 becomes 17/10 and 51 becomes 51/1. Then flip 17/10 and multiply.

51/1 * (10/17) = 510/17

Then simplify.

510/17 = 30

Hope this helps.

Answer:

Roots are x=6 and - 4

Step-by-step explanation:

2(x-6)(x+4)=0

(x-6)=0 or (x+4)=0

x=6 or x=-4, their multiplicities is 1
