Answer:
So wavelength in decimal can be written as 0.00000155 m
Step-by-step explanation:
We have given wavelength of light used in optic fibers is 
We have to convert this wavelength in decimal form
We know that 
can be written as 
So 
So wavelength in decimal can be written as 0.00000155 m

Step-by-step explanation:
The diagram consists of different boxes if the same sizes. Each box is a square with sides measuring 1 cm. The area of each box would be
1 × 1 = 1cm^2
The area of the parallelogram is the total number of squares that it contains. To determine this, the first step is to count the total number of complete squares. Looking at the diagram, there are 11 complete squares. This means
11 × 1 = 11 square units.
The next step is to count the number of incomplete squares and divide by 2. The number of incomplete squares are 8
8/2 = 4
4 × 1 = 4 square units
The area of the parallelogram would be
11 + 4 = 15 square units
Solve the equation we have that:
a. S = 3V²/ 4
b. S = 108 feet
<h3>How to solve the parameters?</h3>
We have the equation to be;
V = 2√3S
Where;
- V is the speed
- S is the length
Let's make S the subject from the formula, divide both sides by 2√2S = v/ 2. Take square of both sides:
Now we need to divide both sides by three:
S = 3V²/ 4
b. If v = 12miles per hour, substituting in the equation found earlier:
S = 3 (12²)/ 4
S= 432/ 4
S = 108 feet
Thus, the formula for the length is S = 3V²/ 4

Answer:
138
Step-by-step explanation:
x is an exterior angle of a triangle.
If you didn't know, an exterior angle of a triangle is equal to the sum of its opposite interior angles.
The opposite interior angles of x have measures of 80 degrees and 58 degrees.
Hence, x = 80 + 58 = 138
