Answer:
The answer to your question are A and D
Step-by-step explanation:
If cos Ф = -2/3 means that
adjacent side = -2 and hypotenuse = 3
Opposite side = =
With this information, this angle can be in the second and in the third quadrangle.
sin Ф can be or sin Ф =
tan Ф or tan Ф =
csc Ф = or csc Ф =
Answer:
28 square units
Step-by-step explanation:
1 x 2 = 2
2 x 4 = 8
4 x 1 = 4
each box it on the figure twice so
2 + 2 + 4 + 4 + 8 + 8 = 28
Answer:
x ∈ R, x ≠ 9
Step-by-step explanation:
Given
f(x) =
The denominator of f(x) cannot be zero as this would make f(x) undefined.
To find the value that x cannot be, equate the denominator to zero and solve for x
x - 9 = 0 ⇒ x = 9 ← excluded value
Thus the domain is x ∈ R, x ≠ 9
