any thoughts? the "vertex" is the highest point of the parabola

1 year ago
mikewwe13:

the third one

1 year ago
Vocaloid:

if it's on the ground, that wouldn't be the highest point any other ideas?

1 year ago
mikewwe13:

not third, fourth or second

1 year ago
mikewwe13:

it's first since you said it's the highest

1 year ago
mikewwe13:

or maybe i'm wrong

1 year ago
Vocaloid:

it's asking about the y-coordinate, what physical property does y represent in this situation? height or time?

1 year ago
mikewwe13:

height

1 year ago
Vocaloid:

good, so the y-coordinate of the vertex would be the highest height which answer choice corresponds with this idea?

1 year ago
mikewwe13:

fourth

1 year ago
Vocaloid:

y is height, not time

mikewwe13:

oh i'm sorry

What does the x-intercept represent? A. The diver was in the air for 2 s. B. The springboard was 2 ft above the surface of the water. C. The diver jumped 2 ft above the springboard. D.

if you look at the parabola, the graph is increasing across a certain range of x values, what would that be?

8

The answer is first

Vocaloid:

any thoughts or ideas so far? I'm not 100% sure myself but I have a few ideas

1 year ago
mikewwe13:

the answer is either C or D

1 year ago
Vocaloid:

the x-intercept occurs when y = 0, so area = 0, so this can't be the max area remember that x represents the length of the fencing used

1 year ago
mikewwe13:

ok not D

1 year ago
Vocaloid:

[this one is kind of hard to conceptualize, but imagine if they take all of the fencing and lay it out on a straight line, this would give us 0 area and the maximum length of fencing 100]

1 year ago
Vocaloid:

so first one is the best choice

1 year ago
mikewwe13:

correct

mikewwe13:

Thank you so much, i couldn't done it without you, you're so smart

Can you believe Toys R us are closing down ?

1 year ago
Vocaloid:

mikewwe13:

I mean this new generation of kids are over the new technology now and Toys R us are shutting down cause Technology took over

1 year ago
mikewwe13:

every time i see a little kid they're on an ipad or iphone

Vocaloid:

I'm going to close this, you could talk about this in the chat/ or open up a new question in the writing section maybe if you still want to talk about this
