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
Answer:
x > 1
Step-by-step explanation:
-26 + 13x + 2 > 2 - 13x (Given)
13x - 24 > 2 - 13x (Add like terms)
26x - 24 > 2 (Add 13x on both sides)
26x > 26 (Add 24 on both sides)
x > 1 (Divide 26 on both sides)
Answer:
3.6
Step-by-step explanation:
convert 120 centimeters to meters by moving the decimal point 2 places to the left and them multiply that by 2 and multiply that by 1.5
Answer:
Explicit: -2*2^(n-1)
Recursive: 2*aₙ₋₁
Step-by-step explanation:
To write a explicit formula for this geometric sequence you follow the following formula/template
Firstnumber*commonratio^(n-1)
Seeing that the common ratio is 2 we can start plugging numbers in and get
-2*2^(n-1)
For a recursive formula we follow the following template
common ratio * the n-1 term
So we could write this as
2*aₙ₋₁
