Find the coordinates of P so that P partitions the segment AB in the ratio 1:7 if A(7,14) and B(−1,−2).

love history [14]

Answer:

P(6, 12 )

Step-by-step explanation:

Using the Section formula, then

$x_{P}$ = $\frac{7(7)+1(-1)}{1+7}$ = $\frac{49-1}{8}$ = $\frac{48}{8}$ = 6

$y_{P}$ = $\frac{7(14)+1(-2)}{1+7}$ = $\frac{98-2}{8}$ = $\frac{96}{8}$ = 12

Hence P(6, 12 )

ELEN [110]

$15(2z+1)^3+10(2z+1)^2-25(2z+1)\\\\subtitute\ x=2z+1\\\\15t^3+10t^2-25t=5t\cdot3t^2+5t\cdot2t-5t\cdot5=5t(3t^2+2t-5)\\\\=5t(3t^2-3t+5t-5)=5t[3t(t-1)+5(t-1)]\\\\=5t(t-1)(3t+5)\\\\=5(2z+1)(2z+1-1)[3(2z+1)+5]\\\\=5(2z+1)(2z)(6z+3+5)=5(2z)(2z+1)(6z+8)\\\\=10z(2z+1)(6z+8)=10z(2z+1)(2)(3z+4)\\\\=\boxed{20z(2z+1)(3z+4)}$
