f(x) is a quadratic equation with the x-side squared and a is positive which means that the graph of the function is a parabola facing up. The range of f(x) is given by {y|y ≥ k}, where k is the y-coordinate of the vertex.

, written in vertex form is

, where (h, k) = (-1, -11)

Therefore, range ={y|y ≥ -11}

pshichka [43]

Step-by-step explanation:

15,729 = 10 000 + 5 000 + 700 + 20 + 9

= (1 x 10000) + (5 x 1000) + (7 x 100) + (2 x 10) + (9 x 1)

We can also write it like this :

(1 x 10⁴) + (5 x 10³) + (7 x 10²) + (2 x 10¹) + (9 x 10⁰)

At a soccer game, 70% of the fans were rooting for the Tornadoes. If 40% of the Tornadoes fans were girls, what percent of the f
IRISSAK [1]

The answer is A.30%

The way I did this problem was from a number line. I don't have a one: so I'll just make one.

10%     20%    30%    40%    50%    60%    70%    80%    90%   100%

So, what you do here is you take out 30% because those are NOT tornadoes fans. 10%     20%    30%    40%    50%    60%    70% .

It says that 40% are girls so... 10%   20%    30%.

Hope you get it right!
