Angle 1 and angle 8 are congruent
Answer:
-3x^2+2xy-4y^2
Step-by-step explanation:
(x^2+xy-3y^2)-(4x^2-xy+y^2)
x^2-4x^2+xy-(-xy)-3y^2-y^2
-3x^2+xy+xy-4y^2
-3x^2+2xy-4y^2
Volume should be 226.08
volume of a cone= 1/3 pi radius squared multiplied by height
6x6=36 multiply by height 36x6=216 divide by 3=72 now multiply by pi =226.08
your answer is 226.08
Answer:
The discriminant is the part under the square root in the quadratic formula, b²-4ac. If it is more than 0, the equation has two real solutions. If it's less than 0, there are no solutions. If it's equal to 0, there is one solution.

Step-by-step explanation:
The CPI increased from 29.6 to 82.4.
The rate of increase, is:
82.4/29.6 = 2.78
Now multiply this rate to the $0.14 price of grapes from 1960.
$0.14 x 2.78 = $0.39
Now to get the amount of increase subtract the new price from the original price:
$0.39 - $0.14 = $0.25 increase.
