[random dagger]

MNP is a triangle such that NP = 6. I is the midpoint of [NP] and H the orthogonal projection of M onto (NP). We have H ∈ [NI] and IH = 2.  Calculate the vectors →NP·→NM and →NP·→PM

Can you please just tell me if it is 6×1 or 6×2 for the first one? I got 6×1 but another person got 6×2

If the first one is right than the second one is too

There is a dot between the vectors

-12 and 7.5

are there any more info given? like info about the point E or that MNP is a right-angled triangle etc?

[tacit glade]

how?

[random dagger]

No

[random dagger]

This is a mistake. There is no point E, it scanned the symbol of belongs to as an E

[tacit glade]

symbol of what?

[random dagger]

Symbol of "belongs to"
