Answer:
The Answer is A. the first one
Step-by-step explanation:
Sorry cant tell you
Tanx = opp/adj
tan39=x/32
(32)(tan39)= 25.9 or approx 26
x = 25.9 or approx 26
Answer:
The correct option is 1.
Step-by-step explanation:
The difference of cubes is defined as
The given expression is
It can be written as
Using the property of exponent, the above expression can be written as
This is a difference of cubes.
Therefore the correct option is 1.
For this case we have the following equation:
-2y2 + 6y = -2
Rewriting we have:
-2y2 + 6y + 2 = 0
Using the quadratic formula we have:
x = (- b +/- root (b ^ 2 - 4 * a * c)) / (2 * a)
Substituting values:
x = (- (6) +/- root ((6) ^ 2 - 4 * (- 2) * (2))) / (2 * (- 2))
Rewriting:
x = (- 6 +/- root (36 + 16)) / (- 4)
x = (- 6 +/- root (52)) / (- 4)
x = (- 6 +/- root (4 * 13)) / (- 4)
x = (- 6 +/- 2 * root (13)) / (- 4)
x = (- 3 +/- root (13)) / (- 2)
The roots are:
x1 = (- 3 - root (13)) / (- 2)
x2 = (- 3 + root (13)) / (- 2)
Rewriting:
x1 = -0.3
x2 = 3.3
Answer:
–0.3, 3.3
Answer:
x= 131
