garik1379 [7]

Answer:

Richard bought 128 total batteries

Step-by-step explanation:

1. Multiply 4 by 4 to find the total batteries in one package

4 * 4 = 16

2. Now we know that there are 16 batteries per package. There are 4 packages in a box. Multiply 16 by 4

16 * 4 = 64

3. 64 represents the total number of batteries in a box. Since Richard bought <u>two</u> boxes, multiply 64 by 2

64 * 2 = 128

Find a quadratic model for the set of values: (-2, -20), (0, -4), (4,-20) Show your work

Usimov [2.4K]

A quadratic function:
$y=ax^2+bx+c$

First, take the point (0,-4) and plug the values (x,y) into the equation:
$-4=a \times 0^2+b \times 0 +c \\
-4=c$

So the equation is $y=ax^2+bx-4$ .

Now plug the values of the other two points into the equation and set up a system of equation:
$-20=a \times (-2)^2+b \times (-2)-4 \\
-20=a \times 4^2+b \times 4-4 \\ \\
-20+4=4a-2b \\
-20+4=16a+4b \\ \\
-16=4a-2b \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ | \div 2 \\
-16=16a+4b \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ |\div 4 \\ \\
-8=2a-b \\
\underline{-4=4a+b} \\
-12=6a \\
\frac{-12}{6}=a \\
a=-2 \\ \\
-8=2a-b \\
-8=2 \times (-2)-b \\
-8=-4-b \\
-8+4=-b \\
-4=-b \\
b=4$

The function is:
$\boxed{y=-2x^2+4x-4}$
