Step-by-step explanation:

Using the definition

n $C_{r}$ = $\frac{n!}{r!(n-r)!}$

where n! = n(n - 1)(n - 2) × 3 × 2 × 1, note that 0! = 1

Given

9 $C_{9}$ = $\frac{9!}{9!(9-9)!}$ = $\frac{9!}{9!(0!)}$ = $\frac{9!}{9!}$ = 1

Which standard form equation below correctly represents the quadratic function

Charra [1.4K]

Answer: 4) y = -1/3x² + 2x - 1

Step-by-step explanation:

Given :

y = $\frac{-1}{3}$ $(x-3)^{2}$ + 2

Expanding (x-3)² will give :

$x^{2}$ - 6x + 9

substituting into the function , we have :

y = $\frac{-1}{3}$ $( [tex]x^{2}$ - 6x + 9 ) + 2

Expanding , we have

y = $\frac{-1}{3}$ $x^{2}$ + 2x - 3 + 2

y = $\frac{-1}{3}$ $x^{2}$ + 2x - 1

4’1” - 1’ 10” whats is

cluponka [151]

Since inches are out of 12 this would be

4 ft - 1 ft = 3 ft

3' 1" - 1 " = 3 '

3 feet is also 2 ft and 12 inches

2' 12" - 9 " = 2' 3"

So the answer is 2 feet and 3 inches

Hope this helps
