He should use the Pythagorean Theorem to find the missing length.
Since KT is tangent to the circle and TL reaches the center of circle L, the measure of angle LTK is 90 degrees. This means that triangle LTK is a right triangle which means the Pythagorean Theorem can be used.
So,
TL²+(12)²=(13)²
=> TL²+144=169
=> TL²=25
=> TL = 5
Therefore, the radius of circle L is 5 feet.
Answer: F (cos(230)).
Explanation:
Cosine corresponds to the x coordinate of points on a circle when the radius is drawn in like this, so the answer would be the cos of that angle, but you have to account for the fact that the 50 degree angle marked is just the reference angle not the entire angle so you have to add 180 degrees to that to get 230.

__________________________________________________________
Step-by-step explanation:
First you had to divide by 2 from both sides of equation.

Simplify.


Divide by the numbers.



Apply the fraction rule.


Then you divide by the number.



Add by 4 from both sides of equation.

Simplify it should be the correct answer.

Answer:
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 206 mg
Sample mean,
= 217.5 mg
Sample size, n = 14
Sample standard deviation, s = 14.9 mg
Claim:
The mean sodium content for the sports drink is not 206 mg. It is different than 206 mg.
Thus, we design the null and the alternate hypothesis
We use two-tailed t test to perform this hypothesis.
T(n) = 0.2n
