What is the amplitude of sin ?
sp2606 [1]

You haven't provided a graph or equation so I will tell the simplified meaning of amplitude instead.

Amplitude, is basically a distance from midline/baseline to the maximum or minimum point.

For sine function, can be written as:

\displaystyle \large{ y = A \sin(bx  -  c) + d}

  • A = amplitude
  • b = period = 2π/b
  • c = horizontal shift
  • d = vertical shift

I am not able to provide an attachment for an easy view but I will try my best!

We know that amplitude or A is a distance from baseline/midline to the max-min point.

Let's see the example of equation:

\displaystyle \large{y = 2 \sin x}

Refer to the equation above:

  • Amplitude = 2
  • b = 1 and therefore, period = 2π/1 = 2π
  • c = 0
  • d = 0

Thus, the baseline or midline is y = 0 or x-axis.

You can also plot the graph on desmos, y = 2sinx and you will see that the sine graph has max points at 2 and min points at = -2. They are amplitude.

So to conclude or say this:

If Amplitude = A from y = Asin(x), then the range of function will always be -A ≤ y ≤ A and have max points at A; min points at -A.

What should be added to 6.125 to get 10
WITCHER [35]
3.875 Should be adding to 6.125 to get 10, however if you want an easier way of checking this. Do 3.875 + 6.125 and you'll get exactly 10. Click thanks <3

You can buy shampoo in a 6 oz bottle for 2.79 or in a 14 oz bottle for 10.89
Lady bird [3.3K]

Answer:

Step-by-step explanation:

Find and compare the unit costs of the two different bottle sizes.

First:  

$2.79/(6 oz) = $0.465/oz

Second:

$10.89/(14 oz) = $0.778/oz

Clearly, the larger (14 oz) bottle is a much better buy
