Answer:
Your answer is D
Step-by-step explanation:
Answer:The period of the sine curve is the length of one cycle of the curve. The natural period of the sine curve is 2π. So, a coefficient of b=1 is equivalent to a period of 2π. To get the period of the sine curve for any coefficient b, just divide 2π by the coefficient b to get the new period of the curve.

Answer:
- boat: 48 km/h
- current: 14 km/h
Step-by-step explanation:
The upstream speed is ...
u = (204 km)/(6 h) = 34 km/h
The downstream speed is ...
d = (372 km)/(6 h) = 62 km/h
The speed of the boat in still water is the average of these values:
b = (34 kph +62 kph)/2 = 48 kph
The speed of the water is the difference between the boat's speed and the speed made good:
w = 48 -34 = 14 . . . km/h
The rate of the boat in still water is 48 km/h. The rate of the current is 14 km/h.
What is the value of the number 3 in the the number 12,532.628
Solution
Here we need to use the place chart. I have attached the place value chart.
According to the place chart 3 is in tens place.
Therefore, the value of the number 3 in the number 12,532.628 is 3 x 10 = 30.
The answer is 30.
Answer:
3.98 cm, 602.18 cm²
Step-by-step explanation:
<u>Given:</u>
<u>To find:</u>
<u>Solution:</u>
- V = πr²h
- h = V/πr² = 800/(π8²) = 3.98 cm
- S = 2πr (r+h) = 16π(8+3.98) = 602.18 cm²
