Fine the equation of the line through (o, -3) perpendicular to y =4x+4

svlad2 [7]

Answer:

The equation of the line is $y = -\frac{x}{4} - 3$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept(the value of y when x = 0).

Perpendicular lines:

If two lines are perpendicular, the multiplication of their slopes is -1.

Line perpendicular to y = 4x + 4.

This line has slope 4, so our line will have slope:

$4m = -1$

$m = -\frac{1}{4}$

$y = -\frac{x}{4} + b$

Through (0, -3)

This means that $b = -3$

$y = -\frac{x}{4} - 3$

The volume of a cylinder is 1.54 litre. If the height is 20 cm

11111nata11111 [884]

Answer:

Radius = 4.95 cm

Step-by-step explanation:

I am assuming you need the radius of the base of the cylinder.

Volume = 1.54 * 1000 = 1540 cm^3

Volume = πr^2h so:

1540 = π*r^2*20

r^2 = 1540/20 π = 24.510

r = 4.95 cm.

Step-by-step explanation:

3=3(x-5)-3(x-6)

3=3x-15-3x+18

3+15-18=3x-3x

18-18=0x

0=0x
