(14cos51, 14sin51)
8.81 i, 10.88 j
Answer:
2
Step-by-step explanation:
this is a 30-60-90 Δ and the ratio of the sides are 1 : 
: 2
1 / 2 = / x
cross-multiply: x = 2
a. 6/22 or 27.27% b. 3/22 or 13.63%
there are 22 days in the range from March 18th till March 30th. each day has a probability of 1/22. add all the days together in a range to find the probability of each. A. 25,26,27,28,29,30 is 6/22 dates. B. 18,19,20 is 3/22.
Answer:
x = 9 ± √14
Step-by-step explanation:
x² − 18x + 67 = 0
Move the constant to the other side:
x² − 18x = -67
Take half of -18, square it, and add to both sides.
(-18/2)² = (-9)² = 81
x² − 18x + 81 = -67 + 81
x² − 18x + 81 = 14
Factor the perfect square:
(x − 9)² = 14
Solve for x:
x − 9 = ±√14
x = 9 ± √14
You can do 8 + 8 = 16 then minus 1 cuz thats how much you added
