Montano1993 [528]

Answer:

a

Step-by-step explanation:

Cylinders:

Ratio of radii = 1 : 4

Radius of two cylinders are: r , 4r

Ratio of height = 3 :1

Height of two cylinders are: 3h , h

Lateral surface area of cylinder =  2πrh

Ratio of lateral surface area= 2π* r * 3h   : 2π* 4r * h

                                             = 3 : 4

Solve the system by graphing.<br> 19) y = x2 + 2x + 7<br> y = 3x – 4
Sedbober [7]

Answer:

  no real solutions

  complex solutions: x = 0.5±i√10.75, y = -2.5±i·3√10.75

Step-by-step explanation:

The graph shows the line and parabola do not intersect, so there are no real solutions to this system of equations.

__

However, the complex x-solutions can be determined from the graph to be ...

  x = 0.5 ±i√10.75

The corresponding y-values can be found from the equation

  y = 3x -4 = 3(0.5 ±i√10.75) -4

  y = -2.5 ± i·3√10.75
