Answer:

5.428571

Step-by-step explanation:

5\frac{3}{7}

take the fraction and divide that:

\frac{3}{7} =0.428571

then just add 5:

5 + 0.428571 = 5.428571

or...

convert the mixed fraction to improper fraction:

5\frac{3}{7} = \frac{38}{7}

divide like normal:

\frac{38}{7} = 5.428571

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.

Which expression is equivalent to 18 1/5- (22 2/5) - (40 1/5)
Mekhanik [1.2K]

Answer: 18 1/5 + 22 2/5 + 40 1/5

Step-by-step explanation:

To get equivalent expression we need to remove the parenthesis multiply negative sign inside the parenthesis when we multiply negative and negative it becomes positive. So the expression becomes 18 1/5 + 22 2/5 + 40 1/5
