Answer:
x = 15
Step-by-step explanation:
The right angle is formed at at the tangent line and the radius
So to solve for the missing angle we can solve for x using the Pythagorean Theorem
The Pythagorean theorem states that the sum of the two legs squared equal the hypotenuse squared
Knowing this we can create an equation to solve for x
now we solve for x
So we can conclude that x = 15
The first option is your answer.
Sigma notation is just a fancy way to shorten a sum of a series of numbers using a set equation. The "n =" tells you where to start in the sequence and the top number tells you where to stop.
Answer:
<u>Recursive:</u>
<u>Explicit:</u>
Explanation:
<u>1. Sequence:</u>
<u>2. Recursive formula</u>
The recursive formula permits to calculate the value of the nth term in the sequence using the (n-1)th term in the sequence.
<u>3. Explicit formula</u>
The explicit formula permits to calculate any value of a term in the sequence:
Diameter = 30
30/2 = 15 15 is the radius
To find area:
3.14 x 15 x 15 = 706.5
706.5 is the answer
9/10 or 0.9
