Sloan [31]

(this is for fractions!!!!!!!!!!!!) 28/5 or 5 3/5

i think u just make it into 5.6/1 multiply by 10 which gets 56/10 and wala
but it's not simplified. 56 and 10 is divisible by 2 so u get 28/5 which is actually 5 3/5 (which is 5.6!!)

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

Fin find the 31st term in -3, -5, -7, -9

vaieri [72.5K]

Answer:

-63

Find common difference:

-5 -(-3)

-5 + 3

-2

nth term:

a + (n-1)(d) <u>[where a is first term, d is common difference]</u>

-3 + (n-1)(-2)

-3 -2n + 2

-2n -1

So 31st term:

-2(31) -1
