What does she have to choose to make her ice-cream

foggy mauve Jun 10, 2023, 10:12 PM

#

The answer is just all of the numbers multiplied together

weary scroll Jun 10, 2023, 10:12 PM

#

Or

#

Is she allowed no topping

#

In which case 3 total

#

foggy mauve The answer is just all of the numbers multiplied together

In the case it's just one scoop and one topping

#

I Didn't get it ?

weary scroll Jun 10, 2023, 10:13 PM

#

If she has to choose a flavour, a cone and a topping (2)

#

Then for each flavour she has any choice of cone and topping

storm yacht Jun 10, 2023, 10:14 PM

#

3x6x2 = the number of choices she has ?

weary scroll Jun 10, 2023, 10:14 PM

#

Yes

storm yacht Jun 10, 2023, 10:15 PM

#

so she has 36 choices only

#

#

Am I correct here ?

weary scroll Jun 10, 2023, 10:16 PM

#

Yes

storm yacht Jun 10, 2023, 10:16 PM

#

Ok thank you

storm yacht Jun 10, 2023, 10:22 PM

#

weary scroll Yes

#

the foucs is (0, 1over2) ?

weary scroll Jun 10, 2023, 10:24 PM

#

Ive forgotten what those terms mean

storm yacht Jun 10, 2023, 10:34 PM

#

Oh nps

weary scroll Jun 10, 2023, 10:35 PM

#

Can you tell me what those mean?

storm yacht Jun 10, 2023, 10:37 PM

#

The point where the parabola intersects its axis of symmetry is vertex

foggy mauve Jun 10, 2023, 10:37 PM

#

weary scroll Can you tell me what those mean?

The focus is a point inside a parabola where any pt on the graph is the same distance from the directrix and focii

so the foucs is (0, 1over2) ?

foggy mauve Jun 10, 2023, 10:40 PM

#

Not quite it should be on the axis of symmetry so the x coordinate has to be 1

#

I'm ngl i forgot to formula for it give me a sec

foggy mauve I'm ngl i forgot to formula for it give me a sec

Ok

(open in browser to view more easily)

#

Put the function in the given form and solve for p and then use it as your y-coordinate for the focus

#

The directrix is the same but with -p instead

storm yacht Jun 10, 2023, 10:54 PM

#

Oh i finally got it
