<h3>Answer: Choice A) y = -10x^2</h3>

Explanation:

The equation y = ax^2+bx+c has the value of 'a' determine how wide or narrow the graph is. The closer 'a' is to zero, then the wider it gets; while the further 'a' is from 0, the narrower it gets.

What we need to do is look for equations in which the 'a' value is furthest from 0. In this case, it's with y = -10x^2 since a = -10 is furthest from zero compared to a = -0.9 and a = 9. Set up a number line to help see this. You can also use absolute values to get the job as well.

Therefore, y = -10x^2 has the most narrowest graph.

PLSSS HELP IF YOU TURLY KNOW THISS
jenyasd209 [6]

Answer:

0.143

Step-by-step explanation:

First of all, you're gonna need to know decimal places

0.143

0=ones

1=tenths

4=hundreths

3=thousandths

So now you know that you need to go to the third decimal place

To get your answer you need to divide your numerator (top number) by your denominator (bottom number)

1÷7=0.14285714

You round up the 2 to a 3 because when rounding you take the closest number that isn't being used and if its larger than 5 then you can round up your number

Lastly, you put your answer in the thousandths decimal place

There ya go! Your answer is 0.143
