Answer:
Well, if you use the quad formula you should get the answer. If you do not know what that means search it up!
Step-by-step explanation:
Answer: D) csc (2π/3)
<u>Step-by-step explanation:</u>
2π/3 is in Quadrant II
Quadrant II has a negative x-value and a positive y-value.
x-values are: cos & sec
y-values are: sin & csc
tan = y/x so will be negative in Quadrant II
A) sec = -
B) tan = -
C) cos = -
D) csc = + this works!
Answer:
(b) 68
Step-by-step explanation:
Distance between two points:
Suppose that we have two points, and . The distance between them is given by:
Diagonal:
Diagonals are a line between opposite points in a square.
In this question, it is between A(0,3) and B(5,0), and between (0,0) and (5,3). Both these diagonals have the same measure, and are the distance between these points. So
Then sum of the squares of its both diagonals is units
Both diagonals measure . Sum of squares is:
The correct answer is given by option b.
Answer:
Step-by-step explanation:
Let "n" be the second odd number in the sequence
(n - 2) + n + (n + 2) + (n + 4) + (n + 6) = 135
5n + 10 = 135
5n = 125
n = 25
23 + 25 + 27 + 29 + 31 = 135

Answer:</h3>
C. x=24, y = 8√3
<h3>
Step-by-step explanation:</h3>
The side ratios in a 30°-60°-90° right triangle are ...
... 1 : √3 : 2 = y : x : 16√3
The shortest side, y, is half the length of the longest, 16√3, so is 8√3.
The mid-length side, x, is √3 times the shortest side, so is 8(√3)(√3) = 24.
The solutions are x = 24, y = 8√3.
