Answer:
YZ = 8.5
Step-by-step explanation:
Since RY is an angle bisector then the ratio of the sides of the triangle are equal to the corresponding ratio of the base, that is
= 
, substitute values
= 
( cross- multiply )
7YZ = 59.5 ( divide both sides by 7 )
YZ = 8.5
Answer:
see explanation
Step-by-step explanation:
Note that cos315° = cos45° and sin315° = - sin45° and
cos45° = sin45° = 
= 
Hence
12(cos315° + isin315°)
= 12(cos45° - isin45°)
= 12( - i )
= 6
- 6i
Answer:
C
Step-by-step explanation:
x = -1 and -7
I believe your answer is 8.
Three times a number less than twice the number and nine is seventeen can be written as: 3n - 2n + 9 = 17
Solve for n as follows:
3n - 2n = n
n + 9 = 17
17 - 9 = 8
Hope this helps! :)
Answer:
2 sales
Step-by-step explanation:
Based on the plot of discrete probability, it can be seen that the distribution is symmetrical and the peak occurs at the stock of 30. If there is a sale of less than 30 such as 20 or 25, the seller is at a loss. Similarly, if the demand is above 30 such as 35 or 40, the seller is also at a loss. Therefore, there is approximately 2 sales to be lost each day based on the decision made by the seller.
