An alloy is composed of nickel, zinc, and copper in a ration of 7:2:9. How many kilograms of each metal are needed to make 3.6kg
motikmotik
Well, the short answer is, we divide that 3.6 by (7+2+9) and then we give as many pieces at the ratio to each, so let's do so,

\bf \stackrel{nickel}{7}~~:~~\stackrel{zinc}{2}~~:~~\stackrel{copper}{9}
\\\\\\
\stackrel{nickel}{7\cdot \frac{3.6}{7+2+9}}~~:~~\stackrel{zinc}{2\cdot \frac{3.6}{7+2+9}}~~:~~\stackrel{copper}{9\cdot \frac{3.6}{7+2+9}}
\\\\\\
\stackrel{nickel}{7\cdot 0.2}~~:~~\stackrel{zinc}{2\cdot 0.2}~~:~~\stackrel{copper}{9\cdot 0.2}
\\\\\\
\stackrel{nickel}{1.4}~~:~~\stackrel{zinc}{0.4}~~:~~\stackrel{copper}{1.8}

Find the coordinates of the center of the given circle. (x - 5)2 + (y + 3)2 = 25 (5, 3) (5, -3) (-5, 3)
Stella [2.4K]

When you write the equation of a circle in the form

(x-x_0)^2+(y-y_0)^2=r^2

Then the center has coordinates (x_0, y_0) and the radius is r

So, in your case, the center is (5,-3) and the radius is 5.

What is the recursive formula for this geometric sequence?<br> 6, -24, 96, -384, ...
djyliett [7]

Answer: a1=6

               An = An-1 - 4

Step-by-step explanation:

N represent what number in the sequence you choose. So in the equation n-1 would be the umber in the equation subtracting 1 then subtracting the difference. The factor you are multiplying by in this sequence is -4. You find the difference by taking any number in the sequence and dividing it by the previous number in the sequence.
