<h2><u>Answer</u><u>:</u><u>-</u><u>1</u><u>9</u><u>3</u></h2>
Step-by-step explanation:
<h3>
Given equation:<u>-</u><u> </u><u>6x²</u><u> + x - 8 = 0</u></h3>
- we know that the discriminant of a quadratic is the expression inside the radical of the quadratic formula.
<h3 /><h3><u>lets </u><u>see:</u><u>-</u></h3>
- 6x² + x - 8 = 0
- b²-4(ac)
- here a= 6,b=1,c=-8
- (1)²-4(6×(-8))
- 1-4(-48)
- 1+192
- 193

Answer:
Step-by-step explanation:
Use trigonometry
<u>Let the height of the cloud be x, then we have:</u>
- tan 35° = x/525
- x = 525 tan 35°
- x = 367.6 (rounded)
The height of the cloud layer is 367.6 m
X is rougly equal to .577350269 or see the graph
<span>-2x + 3y=-1
2x + 5y=25
------------------add
8y = 24
y = 3
</span>-2x + 3y =-1
-2x + 3(3) =-1
<span>-2x + 9 = -1
-2x = -10
x = 2
answer
x = 2 and y = 3 or (2,3)
