area \:  = \pi {r}^{2} \\  circumference  = 2\pi \: r
where r = radius
\pi {r}^{2}  = 28.26 \:  {yd}^{2}  \\  {r}^{2}  = 28.26 \div \pi \\  {r}^{2}  = 8.99 = 9 \\  \sqrt{ {r}^{2} }  = r  =  \sqrt{9}  = 3
circumference = C
c = 2\pi \: r = 2(3) \times \pi \\  = 18.85 \: yd = 18.9 \: yd

the base must be raised

for example

log_{10} 55 = n ( the base is 10 ), then

55 = 10^{n}

Could someone explain this?

Answer:

  2

Step-by-step explanation:

The curve's highest value is -1.

The curve's lowest value is -5.

For a symmetrical wave like this*, the amplitude is half the difference between the highest and lowest values:

  1/2(-1 -(-5)) = 2

The amplitude is 2.

_____

* There is no general agreement as to how to compute the amplitude when the wave is asymmetrical. Some authors use the same formula. Some consider the amplitude to be the maximum deviation from average. Some define only a "peak-to-peak" amplitude in those cases. The meaning of "amplitude" in those cases depends on the context in which the question is asked.
