Answer:

The center of the circle is c=50 and radius of the circle is r=\sqrt{3}

Step-by-step explanation:

Given circle equation is

x^2-4x+y^2+14y=-50\hfill(1)

Equation (1) can be written as x^2-4x+y^2+14y+50=0\hfill(2)

we know that the equation of the circle is of the form

x^2+y^2+2gx+2fy+c=0\hfill(3)

with centre (-g,-f) and radius=\sqrt{g^2+f^2-c}

when, g,f and c are constants

Now comparing the (2) and (3) equations we get 2g=-4

                                                                          g=\frac{-4}{2}

                                                                          g=-2

                                                                          2fy=14

                                                                          f=\frac{14}{2}

                                                                          f=7

                                                                 and  c=50

Now to find the centre and radius of the given circle equation, substituting the values of g,f,c in the formulae of centre and radius

                  centre=(-g,-f)

                             =(-(-2),-7)

                  centre=(2,7)

                  Radius=\sqrt{g^2+f^2-c}

                              =\sqrt{(-2)^2+(7)^2-50}

                             =\sqrt{4+49-50}

                            =53-50

                   Radius=\srqt{3}

The center of the circle is c=50 and the radius of the circle equation r=\sqrt{3}

Which statement is true about the extreme value of the given quadratic equation? y = -3x2 + 12x − 33
Zina [86]

Answer:

The equation has a maximum value with a y-coordinate of -21.

Step-by-step explanation:

Given

y =-3x^2 + 12x - 33

Required

The true statement about the extreme value

First, write out the leading coefficient

Leading = -3

-3 < 0 means that the function would be a downward parabola;

Downward parabola always have their vertex on top of the parabola and as such, the function has a maximum value.

The maximum value is:

x = -\frac{b}{2a}

Where:

a= -3; b =12; c =-33

So, we have:

x = -\frac{12}{2 * -3}

x = -\frac{12}{-6}

x =2

Substitute x =2 in y =-3x^2 + 12x - 33

y = -3*2^2 + 12 * 2 - 33

y = -21

<em>Hence, the maximum is -21.</em>

Given that the mass of an average linebacker at Ursinus College is 250 lbs and the radius of a pea is 0.50 cm, calculate the num
Brilliant_brown [7]

Answer:

1.544*10⁹ Linebackers would be required in order to obtain the same density as an alpha particle

Step-by-step explanation:

Assuming that the pea is spherical ( with radius R= 0.5 cm= 0.005 m), then its volume is

V= 4/3π*R³ = 4/3π*R³ = 4/3*π*(0.005 m)³ = 5.236*10⁻⁷ m³

the mass in that volume would be  m= N*L (L= mass of linebackers=250Lbs= 113.398 Kg)

The density of an alpha particle is  ρa= 3.345*10¹⁷ kg/m³ and the density in the pea ρ will be

ρ= m/V

since both should be equal ρ=ρa , then

ρa= m/V =N*L/V → N =ρa*V/L

replacing values

N =ρa*V/L = 3.345*10¹⁷ kg/m³ * 5.236*10⁻⁷ m³ /113.398 Kg  = 1.544*10⁹ Linebackers

N=1.544*10⁹ Linebackers
