Given: △acm, m∠c=90°, cp ⊥ am

ac: cm=3: 4, mp-ap=1.

find am. ! due in an hour and i have no idea!

 The answer is

Step-by-step explanation:  Given in the question that ΔAM is a right-angled triangle, where ∠C = 90°, CP ⊥ AM, AC : CM = 3 : 4 and MP - AP = 1. We are to find AM.

Let, AC = 3x and CM = 4x.

In the right-angled triangle ACM, we have

Now,

Now, since CP ⊥ AM, so ΔACP and ΔMCP are both right-angled triangles.

So,

Comparing equations (A) and (B), we have

Thus,

b. f(x) = –√x + 3this is the correct answer
