Answer:
the measure of an angle formed by two secants, two tangents, or a secant and a tangent drawn from a point outside the circle is equal to half the difference of the measures of the intercepted arcs.

Answer:
The total number of reading schedules is
Step-by-step explanation:
Recall that if we have n elements, the number of ways in which we can choose k elements without minding the order is .
At first, suppose that we have already chosen 9 books. If we want to number the order in which we are reading this books from 1 to 9, for position 1 we have 9 options, for position 2, we have 8 and so on. Using the multiplication principle, we have that the number of ways or arranging 9 books is 9!
Recall that we want the same amount from novels, plays and nonfiction. That is, we are choosing 3 books from each group. We can easy calculate the total number of ways of choosing the 9 books by simply multiplying the number of ways we choose 3 from each cathegory. Hence the total number of ways of choosing the 9 books is
For each selection of 9 books, we have 9! different ways of organizing them, then the total number is
Answer:
Step-by-step explanation:
If we want to share £5 to the ratio of 1/3 we should follow this steps :
- our ratio is 1/3 so we should add 1 and 3 together to find the total number of parts : 1+3=4
- divide the total amount by the number of parts : 5/4 = 1.25
- multiply each number in the ratio by 1.25 : 1.25*1=1.25 and 1.25*3=3.75
the answer is 1.25 and 3.75
It was obvious from the beginning that the answer would be the last one since ut had two numbers
- following the same steps you get again in the second question :
6 ; 14
Answer:
none of the above
Step-by-step explanation:
The problem as written cannot have any of the solutions offered.
For any of those choices, the right side expression will be irrational. The left side expression will be rational for any rational value of x, so cannot be equal to the right-side expression.
The solution is an irrational number near ...
x ≈ 1.33682898582
