Answer:
see explanation
Step-by-step explanation:
Using identities
sec²x = tan²x + 1
cosec²x = cot²x + 1
cos²x =
(1)
sin²θ +
= sin²θ + cos²θ = 1
(2)
9sec²θ - 9tan²θ
= 9sec²θ - 9(sec²θ - 1)
= 9sec²θ - 9sec²θ + 9
= 9
(3)
- 8cot²A + 8cosec²A
= - 8cot²A + 8(cot²A + 1)
= - 8cot²A + 8cot²A + 8
= 8
(4)
- 10cosec²β + 10cot²β
= - 10(cot²β + 1) + 10cot²β
= - 10cot²β - 10 + 10cot²β
= - 10

Answer:
25/416
Step-by-step explanation:
Maybe you want to know the value of ...
(1 1/4)/(20 4/5) = (5/4)/(104/5) = (5/4)×(5/104) = (5×5)/(4×104) = 25/416
Answer:
31°
Step-by-step explanation:
Rotations about the origin are rigid transformations, meaning that they preserve segment length and angle measure. Therefore, since ∠BCD and ∠B'C'D' are corresponding angles, we know that m∠BCD ≅ m∠B'C'D' = 31°.
Subtract the minimum data value from the maximum data value to find the data range,so in this case yur data range is
10 - 0.08 = 9.92
so yur answer is 9.92
Given : (5x + 8 - 6x) (4 + 2x - 7)
The given question can be written as : (8 - x) (2x - 3)
⇒ 8(2x - 3) - x(2x - 3)
⇒ 16x - 24 - 2x² + 3x
⇒ -2x² + 19x - 24
