Step-by-step explanation:
Process
1.- Use the exponent law "Power"
2.- Simplify
3.- Use the exponent law "Negative exponent"
4.- Conclusion
He should have applied the exponent -3 to 4 to get
A quadratic equation has either two different real roots, one real root, or two conjugate complex roots (this is the case when the discriminant is negative, i.e. when you have no real roots).
Two conjugate complex roots have the same real part and opposite imaginary parts. So, the solutions to Amina's equation will be in this form:
For some
Answer:
$750 cost of the washer.
Step-by-step explanation:
3x+x=1,000
4x=1,000
x=1,000/4
x=$250 cost of the dryer.
3*250=$750 cost of the washer.
Proof:
750+250=1,000
1,000=1,000
Answer:
I don't think it can, because the two smaller sides cannot have a sum of less than the third side. 6+6=12, and 12 is less than 15, so it cannot be possible. You can even test this out on a piece of paper and you will see that it is not possible.
Let P(x,y) be a point on the parabola. The definition of a parabola is the squared distance from P to focus F(2,2) equals the squared distance to the directrix x=8.
squared distance from P(x,y) to focus F(2,2)
(x - 2)² + (y - 2)²
squared distance from P(x,y) to the directrix x=8.
(x-8)²
Those are equal in a parabola,
(x - 2)² + (y - 2)² = (x-8)²
x² - 4x + 4 + y² - 4y + 4 = x² - 16x + 64
y² - 4y - 46 = -12x
That's a sideways parabola,
x = -(y² - 4y - 46)/12
