Simplify 4 n5 + 3.5 n5 + (-2.1 n5 ).
Alona [7]

Step-by-step explanation:    

<u>Step 1: Let's simplify step-by-step.</u>

4n^5 + 3.5n^5 - 2.1n^5

= 4n^5 + 3.5n^5 +  -2.1n^5

<u>Step 2: Combine Like Terms:</u>

= 4n^5 + 3.5n^5 + -2.1n^5

= (4n^5 + 3.5n^5 + -2.1n^5)

= 5.4n^5

 

Answer:    

=5.4n^5

 

Hope this helps.

Derive the equation of the parabola with a focus at (−5, 5) and a directrix of y = −1. (2 points)
umka2103 [35]

Focus of the parabola is (-5,5) and directrix is y = -1.

Let's assume a point (x,y) on parabola.

According to definition of parabola, the distance between point (x,y) and focus (-5,5) would be same as the distance between the point (x,y) and directrix y = -1.

\sqrt{(x+5)^2+(y-5)^2} = \sqrt{(y+1)^2} \\\\(x+5)^2+(y-5)^2=(y+1)^2 \\\\(x+5)^2 + y^2 - 10y +25 = y^2 +2y +1 \\\\(x+5)^2 =  -y^2 +10y -25 + y^2 +2y +1 \\\\(x+5)^2 = 12y -24 \\\\12y =  (x+5)^2  +24 \\\\ y = \frac{1}{12} (x+5)^2  +2

Hence, option D is correct, i.e. f(x) = one twelfth (x + 5)2 + 2.

cupoosta [38]
Check the picture below.

\bf 5i\implies \stackrel{a}{0}~~\stackrel{b}{+5}i\implies \stackrel{\stackrel{absolute~value}{modulus}}{r=\sqrt{a^2+b^2}}\implies r=\sqrt{0^2+5^2}\implies r=5
