A cylinder fits inside a square prism as shown. For every
cross section, the ratio of the area of the circle to the area
of the square is for pi/4
Since the area of the circle is
volume of the cylinder equals
the area of the square, the
Cross section
the volume of the prism or (21)(h) or arh.
the volume of the prism or L (42)(h) or 2nrh.
the volume of the prism or (2)(h) or Iph.
the volume of the prism or (472)(h) or arh.

i dont really.know

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
