Answer:
Angle 1 = 41°
Step-by-step explanation:
Since they are both vertical angles
(6x+11)° = (10x-9)°
6x - 10x = -9 - 11
-4x = -20
4x = 20
x= 5.
Therefore,
Angle 1 = 6(5) + 11
Angle 1 = 30 + 11
Angle 1 = 41°
Answer:
You have completed only half in a 1/4 of a day
Step-by-step explanation:
think of it this way
lets say in half a day e.g at 12pm you finish the report
half of 12 is 6
so that would be a 1/4 of the day
100%=24 hours=whole day
50%=12 hours=half a day
25%=6 hours = quarter of a day
25% = 1/4
i hope this helps
The formula to finding a discriminant would be b^2-4ac, the b value of this trinomial being -5, the a value being 2, the c value being 3. Then, you plug the values in the equation and solve: (-5)^2-4(2)(3)
This would simplify to 1, meaning there are two solutions since the discriminant value is positive. If it is 0, there is one solution, if it is negative, then there are no real solutions.
Roots are the same as zeros, and you find them by factoring and solving for y. This one is easiest if done by "taking roots" method. Let's move the 176 over to the other side and then divide both sides by 4 to get the x^2 alone. If we do that have we get x^2 = -44. But we know that we cannot take the square root of a negative number without accounting for it by using the imaginary "i". Since "i" is equal to -1, let's rewrite that [sqrt-44] as [sqrt(-1)(44)]. Now let's simplify the 44 by finding its perfect square hidden in there: [sqrt(-1)(4)(11)]. Now, because -1 = i^2, we can rewrite that as well like this:
[sqrt(i^2)(4)(11)]. Both the i^2 and the 4 are perfect squares so that's what we pull out, leaving the 11 inside for an answer of x = +/- 2i[sqrt(11)]
