Answer:
Input:
14 x^2 + 57 x - 27
Plots:
Geometric figure:
parabola
Alternate forms:
(7 x - 3) (2 x + 9)
x (14 x + 57) - 27
14 (x + 57/28)^2 - 4761/56
Roots:
x = -9/2
x = 3/7
Polynomial discriminant:
Δ = 4761
Properties as a real function:
Domain
R (all real numbers)
Range
{y element R : y>=-4761/56}
Derivative:
d/dx(14 x^2 + 57 x - 27) = 28 x + 57
Indefinite integral:
integral(-27 + 57 x + 14 x^2) dx = (14 x^3)/3 + (57 x^2)/2 - 27 x + constant
Global minimum:
min{14 x^2 + 57 x - 27} = -4761/56 at x = -57/28
Definite integral:
integral_(-9/2)^(3/7) (-27 + 57 x + 14 x^2) dx = -109503/392≈-279.344
Definite integral area below the axis between the smallest and largest real roots:
integral_(-9/2)^(3/7) (-27 + 57 x + 14 x^2) θ(27 - 57 x - 14 x^2) dx = -109503/392≈-279.344
Step-by-step explanation:
Answer:
0 sec. I help him get the tourist too :)
Step-by-step explanation:
jk, but her cub takes 13 and the mama 4
Step-by-step explanation:
sum of four angles=360°
a=128
b=126
c=54
d=?,let d=x
128+126+54+x=360°
308+x=360
find like terms
x=360-308
x=52°
Plug 129 for x
(-12 x 129)+(14 x 129)-(6 x 129)
Which would be -1548+1806-774
Which equals -516
Rectangle and square
However, I would need to know which figures are involved seeing as there are no pictures of anything to work with.
