1. given:
csc(x) + sin(x)
2. definition of csc(x) :
1/sin(x) + sin(x)
3. combining fractions with a common denominator:
(1 + sin²(x))/sin(x)
4. expanding 1 = cos²(x) + sin²(x) :
(cos²(x) + sin²(x) + sin²(x))/sin(x)
5. simplifying:
(2 sin²(x) + cos²(x))/sin(x)
6. employing the same identity as in (4) :
(2 (1 - cos²(x)) + cos²(x))/sin(x)
7. expanding 2 (1 - cos²(x)) :
(2 - 2 cos²(x) + cos²(x))/sin(x)
8. simplifying:
(2 - cos²(x))/sin(x)
Answer:
48,0675
Step-by-step explanation:
como que vende los zapatos a 55,25 entonces lo divides entre 100 y lo multiplicas por 87 que es el porcentaje
que gana
If the span is 16-ft, then the half-span is 8-ft.
Pitch = (rise) / (half-span) = 6/8 = 3/4 or 0.75 or 75% .
That's a VERY steep roof !
12? im not sure
i think u need to multiply 6 and 2 to get your answer.
Answer:
2/17 Orange
Step-by-step explanation:
1. 2/3 x 12/17 x 1/4 with cancelling 2 and 4 and 3 and 12 becomes...
1/1 x 4/17 x 1/2
2. 1/1 x 4/17 x 1/2 = 4/34 = 2/17
