Is angle LK 77 degrease??
Answer:
Option (C)
Step-by-step explanation:
Given function is F(x) = x³+ 4x² + x - 6
Possible rational zeros of this function = 
[Possible rational zeros of a function f(x) = ax³+ bx² + cx + d,
= 
]
Let the possible zero of this function is 2.
Now do the synthetic division,
2| 1 4 1 -6
<u> ↓ 2 12 26 </u>
1 6 13 20
Here all the numbers at the bottom are positive by dividing with a positive number 2, therefore, 2 is the upper bound.
There will be no rational zero (Positive) above 2.
Therefore, Option (C) will be the answer.
Answer:
We'll be making 35 liters of 19% glucose.
How much of a 15% solution and a 35% solution do we mix in order to get 35 liters of a 19% glucose solution?
X = liters of 15% and Y = liters of 35%
(.15 X + .35 Y) / 35 = .19
The number of Y liters will equal (35 -X) so the equation becomes
(.15 X + .35 *(35-X) ) / 35 = .19
(.15X + 12.25 -.35X) / 35 = .19
(-.20 X / 35) + (12.25 / 35) = .19
(-.20 X / 35) + .35 = .19
(-.20 X / 35) = -.16
-.20X = -5.6
X = 28 liters of 15% and
Y = 7 liters of 35% glucose
Answer is "c" 28 liters
One of the triangles (that on the left, top) has 2 equal sides, and thus is isosceles. The angle immediately adjacent to and to the right of 110 degrees is 180-110 degrees, or 70 degrees, which means that angle 1 is also 70 degrees. The remaining angle is 180 degrees less 2(70 degrees), or 40 degrees; thus, angle 2, immediately adjacent to and to the right of this 40 degree angle, is 180-40, or 140 degrees. The triangle to the right and below the horiz. line has angle 40 degrees (using the principle of vertical angles); thus, angle 3 is 180-(40+90) degrees, or 50 degrees.
The Answer is = 8x^4
Hope this helps! :)
