Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identity
sin²x + cos²x = 1 , then
sin²x = 1 - cos²x and cos²x = 1 - sin²x
Consider the left side
← expand numerator/denominator using FOIL
= 
= 
= 
= 
= cot²A = right side , thus proven
Answer:
<h2><u><em>
66,130</em></u></h2>
I just guessed random numbers until I got 66 and 130.
Step-by-step explanation:
Simple interest =P (1+. R )^n
/100
Where P is the amount
R is rate (%)
n is number of years
So if you are given months your divide ➗ the number of months by 12 years
2710 *(1+ [ 3.8/100])^3/12
Answer:
49π in²
Step-by-step explanation:
Step 1: Find the radius.
- To find radius given diameter, just divide the diameter by 2:
- 14/2 = 7, so the radius is 7.
Step 2: Apply area of circle formula.
- The formula to find the area of a circle is πr², where r = radius.
- Now, plug in the value of r: π(11)².
Step 3: Simplify.
Since we're finding the area in terms of pi, we don't have to multiply 121 by pi, so the answer is 49π in².
