In the formula of the distance between a point and a plane (not any plane but a plane parallel to the original one, equation [1] ), keeping <span>D=2</span>, and d as d itself, we get:
<span><span>D=<span><span>|a<span>x1</span>+b<span>y1</span>+c<span>z1</span>+d|</span><span>√<span><span>a2</span>+<span>b2</span>+<span>c2</span></span></span></span></span>
<span>2=<span><span><span>∣∣</span>1⋅0+2⋅0+<span>(−2)</span>⋅<span>(−<span>12</span>)</span>+d<span>∣∣</span></span><span>√<span>1+4+4</span></span></span></span>
<span><span>|d+1|</span>=2⋅3</span> => <span><span>|d+1|</span>=6</span>First solution:
<span>d+1=6</span> => <span>d=5</span>
<span>→x+2y−2z+5=0</span>Second solution:
<span>d+1=−6</span> => <span>d=−7</span>
<span>→x+2y−2z−7=<span>0</span></span></span>
Answer:
I choose 1 and multiplied by 3 and then by 4 so that is 7. 7squared is 49
Answer:
20% of a spig is a spug.
Step-by-step explanation:
Spig = I
Spoog = O
Speeg = E
Spug = U
.4I = O
.25E = O
.7E = U
1I = 5 U To get the percentage of spigs we divideeach side by 5 to get spugs.
1 I / 5 = 5 U / 5
1/5 I = U
1/5 = .2 = 20%
.2I = U
20% of a spig is a spug.
