Answer:
Maximum frequency deviation is 2616.29509 Hz
Maximum frequency deviation=(4000-3000)cos45
Max frequency deviation=2616.29509 Hz
Answer:
Sample mean
Sample variance
Sample proportion
Step-by-step explanation:
Answer: 5
Because the two angles are congruent, these sides are congruent, so:
5x-8=2x+7
3x=15
x=5
Answer: 
Step-by-step explanation:
A line that cuts a circle at two points is called "secant".
There is a theorem known as "Intersecting Secant Theorem". This is the theorem you need to use to find the value of "d".
According the Intersecting Secant Theorem:

Having this expression, the next step is to solve for "d":
Use Distributive property:

Subtract 256 from both sides:


Divide both sides by 16:

The value of "d" rounded to the nearest tenth is:
