Mathematics
1 answer:
pickupchik [31]3 years ago
4 0

Answer:

The second graph

Step-by-step explanation:

In all the other ones the same x coordinate is graphed twice. What makes a function is the x not being there twice, and the only one that shows that is the second graph. Sorry if I'm wrong.

Help!!,!, please
Crank

Answer:

y = 2x + 4

y = 2x + 46x – 3y = -12

y = 2x + 46x – 3y = -12And

y = 2x + 46x – 3y = -12Andy = 2x

y = 2x + 46x – 3y = -12Andy = 2x-8x – 2y = 24

Step-by-step explanation:

An angle whose measure is 405° is in standard position. In what quadrant does the terminal side of the angle fall?
katrin2010 [14]

Answer:

The angle is in the first quadrant

Step-by-step explanation:

For angles greate than360°,subtract

360° from the angle until the angle is less than 360°. Hence

405° = 405° - 360°

= 45°

The angle is in the first quadrant. Since the first quadrant can still take as much as 90°

A homogeneous rectangular lamina has constant area density ρ. Find the moment of inertia of the lamina about one corner
frozen [14]

Answer:

I_{corner} =\frac{\rho _{ab}}{3}(a^2+b^2)

Step-by-step explanation:

By applying the concept of calculus;

the moment of inertia of the lamina about one corner I_{corner} is:

I_{corner} = \int\limits \int\limits_R (x^2+y^2)  \rho d A \\ \\ I_{corner} = \int\limits^a_0\int\limits^b_0 \rho(x^2+y^2) dy dx

where :

(a and b are the length and the breath of the rectangle respectively )

I_{corner} =  \rho \int\limits^a_0 {x^2y}+ \frac{y^3}{3} |^ {^ b}_{_0} \, dx

I_{corner} =  \rho \int\limits^a_0 (bx^2 + \frac{b^3}{3})dx

I_{corner} =  \rho [\frac{bx^3}{3}+ \frac{b^3x}{3}]^ {^ a} _{_0}

I_{corner} =  \rho [\frac{a^3b}{3}+ \frac{ab^3}{3}]

I_{corner} =\frac{\rho _{ab}}{3}(a^2+b^2)

Thus; the moment of inertia of the lamina about one corner is I_{corner} =\frac{\rho _{ab}}{3}(a^2+b^2)
