Two rational real solutions -8 & +8
We are given that the passenger's jet is flying at a speed of 185 miles per hour, with a direction of 36 degrees, and the wind speed being 47 mph with a direction of 120 degrees. From this, you could create a diagram is shown in the attachment.
[ 185 cos 36, 185 sin 36 ]
+ [ 47 cos 120, 47 sin 120 ]
_______________________
[ 185 cos 36 + 47 cos 120, 185 sin 36 + 47 sin 120 ]
√( 4263 + 33988 )^2
= ( About ) √38251 = 195.57 mph
<u><em>Solution = 195.6 mph, 069° </em></u>
Answer:
(36) (x+6) (-10 or -2) i got this right on (ed)
Step-by-step explanation:
1 Add to both sides of the equation. The value of in this equation is 36.
2 Write the left side of the equation as a binomial squared. The left side of the equation becomes (x +6)2.
3 Use the square root property of equality.
4 Isolate the variable: x = -10 or -2
Well, here's a harder one
Basically, to find a vertical asymptote, we set the denominator to 0. Like this:
x^3 - 81x = 0
Then we solve for x.
x(x^2 - 81) = 0
x(x+9)(x-9) = 0
x = 0, 9, -9
There are vertical asymptotes at x = 0, x = 9, and x = -9.
