Answer:
Not Enough Information.
Step-by-step explanation:
Recall that
sin²(<em>θ</em>) + cos²(<em>θ</em>) = 1
for all <em>θ</em>, and given that cos(<em>θ</em>) < 0, we find that
cos(<em>θ</em>) = -√(1 - sin²(<em>θ</em>)) = -√(1 - (2/5)²) = -√(21)/5
Now,
csc(<em>θ</em>) = 1/sin(<em>θ</em>) = 1/(2/5) = 5/2
and
cot(<em>θ</em>) = cos(<em>θ</em>)/sin(<em>θ</em>) = (-√(21)/5)/(2/5) = -√(21)/2
Answer:
Step-by-step explanation:
first off he took the photo at -20 feet below sea level
expression colud be -11+8+-13
and the answer for the expression would be -20 i do hope this helps
5x=-35 divide both sides by 5 to get
x=-7
The answer is B
Answer:
-4
Step-by-step explanation:
The two equations you have are:
y = 3x - 7
x = 1 (this comes from the x value being 1)
To solve for y, use the substitution property of equality to replace x in the equation:
where x = 1,
y = 3(1) - 7
y = -4
