mafiozo [28]2 years ago
7 0

The equation of a straight line with gradient m passing through the origin is:

\displaystyle y=mx

The line passes through the origin, so the y-intercept is 0

\displaystyle y=mx+b

\displaystyle y=mx+0

\displaystyle y=mx

Which relationship is always true for the angles r, x, y, and z of triangle ABC?
mariarad [96]

That's the second one,


180 - x = r


Whenever two lines cross we get congruent opposite angles and supplemental adjacent angles, i.e. they add to 180 degrees.


The first one is almost right; we have r+y+z=180 and r+x=180 so x=y+z not quite what was written.

A cone has a volume of 226.08 cubic millimeters and a height of 6 millimeters. What is its
dezoksy [38]

Answer:

r≈5.36656314

Step-by-step explanation:

Since A=πr(r+\sqrt{h^2+r^2}) so we get that 226.08/pi≈72 or 226.08/3.14=72 we then plug it in to get 72=r(r+\sqrt{36+r^2}) so we get r≈5.36656314

ANSWER

(x - 5) ^{5}  =  {x}^{5}  - 25 {x}^{4} + 250 {x}^{3}   - 1250 {x}^{2} + 3125x- 3125

EXPLANATION

From the Pascal's triangle,

The coefficients are :

1, 5, 10,10, 5,1

Because of the negative sign, the expansion will alternate sign.

(x - y) ^{5}  =  {x}^{5}  - 5 {x}^{4} y + 10 {x}^{3}  {y}^{2}  - 10 {x}^{2}  {y}^{3}  + 5x {y}^{4}  -  {y}^{5}

We now put y=5 into the expansion to get,

(x - 5) ^{5}  =  {x}^{5}  - 5 {x}^{4} (5) + 10 {x}^{3} ( {5}^{2})  - 10 {x}^{2}  ({5})^{3}  + 5x( {5})^{4}  - {5}^{5}

(x - 5) ^{5}  =  {x}^{5}  - 25 {x}^{4} + 250 {x}^{3}   - 1250 {x}^{2} + 3125x- 3125
