Answer:

The red one is electron since it is in the outer part of the atom.

The black ring is nucleus since it is where the protons are nuetrons are enclosed in.

The blue one is proton, since the number of electrons is equal to the number of protons.

Therefore, the last one, yellow, is Neutrons.

Hope u understand

Please mark as brainliest

Thank You

Step-by-step explanation:

If 15 is the total then it goes on the other side of the equal sign. You have one side so if you add it to the missing side it should equal 15.

Find the equations of the tangents to the curve y = x²-x-12 at each of the points where the curve crosses the x-axis.

poizon [28]

Step-by-step explanation:

First, find the zeroes of the parabola

${x}^{2} - x - 12$

${x}^{2} - 4x + 3x - 12$

$x(x - 4) + 3(x - 4)$

$(x + 3)(x - 4) = 0$

$x = - 3$

$x - 4 = 0$

$x = 4$

So the zeroes or where the curve crosses the x axis is at 4 and -3.

Now, we take the derivative of the function.

$\frac{d}{dx} ( {x}^{2} - x - 12) = 2x - 1$

Plug in -3, and 4 into the derivative function

$2( - 3) = - 7$

$2(4) - 1 = 7$

So at x=-3, our slope of the tangent line is -7 and must pass through (-3,0). So we use point slope formula.

$y - y _{1} = m(x - x _{1})$

$y - 0 = - 7(x - ( - 3)$

$y = - 7x - 21$

At x=4, our slope of tangent line is 7, and pass through (4,0) so

$y - 0 = 7(x - 4)$

$y = 7x - 28$

So the equations of tangent is

$y = - 7x - 21$

$y = 7x - 28$
