Sorry if this is wrong I don't know a lot about circle arcs
Answer:
sec²-2scθ+tanθ+tan²θ=1-sinθ/1+sinθ
sec²-2scθ+tanθ+tan²θ
= 1+sin²θ-2sinθ/cos²θ
=-1+sinθ/1+sinθ
=1-sinθ/sinθ+1
1-sinθ/sinθ+1=-1+sinθ/1+sinθ True
Answer:
Percentage increases and decreases, are found by setting the problem up proportionally.
You are trying to find what percentage of 17.37 is 8.30 first.
so What %/100 = 8.30/17.37
Now define a variable:
Let x = What%
x/100 = 8.30/17.37
17.37x = 830
x = 830/17.37
x ≈ 47.78
8.30 is approximately 47.78% of 17.37, so the percentage decrease is 100% - 47.78% = 52.22%
The percentage decrease is approximately 52.22%
Answer:
25 degrees below zero, -3, 32, 34, 78
Answer:
275.63 mm^2
Step-by-step explanation:
The measurements of the pyramids are
Edge length: 10
Egde width: 8.66 (because 10x8.66/2 = 43.3)
Height: 9
To find the surface area, use this formula, and you will get 275.63:
