The $20 estimate is too low. $5.68 was incorrectly rounded down. It should have been rounded up to $6. The correct estimate should have been $24, so $20 will not be enough to buy 4.1 pounds of cherries
Answer:
Step-by-step explanation:
Given is a differential equation of III order,

The characteristic equation would be cubic as

By trial and error, we find that

Thus m=2 is one solution
Since given that
is one solution we get
m = -4+i and hence other root is conjugate 
Hence general solution would be

The first statement, XZ ⊥ XY and XY = XZ = 5 proves that the triangle XYZ is isosceles.
One isosceles triangle has two congruent sides and two congruent angles.
And you should also know the theorem that states that if two sides of a triangle are congruent then the two angles opposite that sides are also congruent.
So, given that the two sides XZ and XY are congruent, their opposite sides are also congruent, and that proves that the the triangle is isosceles.
