In the ΔABC, the altitude AN= 24 in, BN= 18 in, AC = 40 in. Find AB and BC. Consider all possible cases:Case 1 : N∈BC, AB = ___in, BC = ___in. Case 2 : B∈NC, AB = in, BC =in. Case 3 : C∈BN, AB = in, BC = in. Leave unused fields blank.
On your explanation & answer please be clear. Thanks.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
