Answer:
sin(∅) = -√65/65
Step-by-step explanation:
The identities that relate the cotangent, the cosecant, and the sine are ...
csc² = 1 +cot²
sin = 1/csc
_____
For the given values, we find ...
csc(∅)² = 1 +cot(∅)² = 1 +8² = 65
csc(∅) = -√65 . . . . . . . . . . . . . . . . square root with attention to sign
sin(∅) = -1/√65 = (-√65)/65
The first equation is 
(Equation 1)
The second equation is
(Equation 2)
Putting the value of x from equation 1 in equation 2.
we get,


by simplifying the given equation,


Using discriminant formula,


Now the formula for solution 'x' of quadratic equation is given by:


Hence, these are the required solutions.
Answer:
f(5)= -85
Step-by-step explanation:
f(x)= 1-3x-61-10
now,
f(5)= 1-3×5-61-10
=1-15-71
=--85
hope u want this..
Answer: 12 cups
Step-by-step explanation:
Number of slices in a cake = 8 slices
Number of cups of icing used by each slice = 1/3
Number of cups of icing for each cake will then be:
= 1/3 × 8
= 8/3
= 2 2/3 cups of icing
If she plans to bake 4 1/2 cakes, the number of cups of icing will she use will be:
= 4 1/2 × 2 2/3
= 9/2 × 8/3
= 72/6
= 12 cups of icing
