Y = 2x^2 - 5x
y = x(2x - 5)

x intercepts:-

x(2x - 5) = 0 so these are 0 and 5/2  = 2.5  That is at points (0,0) and (2.5,0)
(Answer)

y-intercept  is when x = 0   so its at 2(x)^2 - 5(0)  = 0 

y intercept at (0,0) Answer

Turning point:-

the x coordinate will be at (2.5 -0 / 2 = 1.25
y coordinate is at  2(1.25^2) - 5*1.25 = -3.125

Turning point is at (11.25,-3.125) Answer

Find the distance between the points (1,8) and (9, 2).
grin007 [14]

Answer:

distance = \sqrt{(x_{1} -x_{2})^2+(y_{1} -y_{2})^2  }\\\\

             =\sqrt{(9-1)^2+(2-8)^2  }\\\\=\sqrt{8^2 + 6^2}\\\\=\sqrt{64 +36 }\\\\=\sqrt{100} = 10units

Can somebody please help answer this word problem using grass method? And showing how u get the answer thanks!!!
siniylev [52]

Answer:

0.25m or 1/4m

Step-by-step explanation:

Given Height of Dorsal Fin = 1/6 of Length of whale Sculpture,

and given length of whale sculpture = 1.5m or 1\frac{1}{2} m\\

Height of Dorsal fin on scuplture = (\frac{1}{6})(1\frac{1}{2} )\\

= (\frac{1}{6} )(\frac{3}{2}) \\= \frac{3}{12} \\= \frac{1}{4}m or 0.25m

What is the completely factored form of d4 -8d2 + 16
irinina [24]
According to Vieta's Formulas, if x_1,x_2 are solutions of a given quadratic equation:

ax^2+bx+c=0

Then:

a(x-x_1)(x-x_2) is the completely factored form of ax^2+bx+c.

If choose x=d^2, then:

\displaystyle x^2-8x+16=0\\\\x_{1,2}= \frac{8\pm  \sqrt{64-64} }{2}=4

So, according to Vieta's formula, we can get:

x^2-8x+16=(x-4)(x-4)= (x-4)^2

But x=d^2:

d^4-8d^2+16=(d^2-4)^2=[(d+2)(d-2)]^2=(d+2)^2(d-2)^2
