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
Answer:
d=(−3−4)2+(−7−(−7))2−−−−−−−−−−−−−−−−−−−−√
d=(−7)2+(0)2−−−−−−−−−−√
d=49+0−−−−−√
d=49−−√
d=7
Hope This Helps!!!
Full year membership=$325
Monthly membership= (30)(12)=360+ 100 upfront fee.
Full year membership =$325
Mounted membership =$460
Full year membership is $100 cheaper.
P = $2000
R = 5.4%
T = 2 yrs
Interest = PTR/100 = 2000*2*5.4/100 = $216
Balance = $2000 + $216 = $2216
Answer:
y= 3x^{3} + 10
Step-by-step explanation:
* 3(x) = 3x
* 3(2) = 6
* x^{2} + 3x = 3x^{3} because you add the x's
* 6+4 = 10
hope that helps if not i can try to go more in depth :)
