Pls answer will mark Brainy m

Tpy6a [65]

Answer:

d(4) = 64

Step-by-step explanation:

Using the recursive formula

d(n) = d(n - 1) + 17 with d(1) = 13, then

d(2) = d(1) + 17 = 13 + 17 = 30

d(3) = d(2) + 17 = 30 + 17 = 47

d(4) = d(3) + 17 = 47 + 17 = 64

A(x, 1), B(5,3) and C(4,-3) are the vertices of triangle ABC. If AB=AC, find the value of x

Molodets [167]

$\\ \rm\longmapsto AB=AC$

$\\ \rm\longmapsto \sqrt{(x-5)^2+(1-5)^2}=\sqrt{(x-4)^2+(1+3)^2}$

$\\ \rm\longmapsto (x-5)^2+(-2)^2=(x-4)^2+4^2$

$\\ \rm\longmapsto (x-5)^2+4=(x-4)^2+16$

$\\ \rm\longmapsto (x-5)^2-(x-4)^2=16-4=12$

$\\ \rm\longmapsto x^2-10x+25-x^2+8x-16=12$

$\\ \rm\longmapsto -2x+9=12$

$\\ \rm\longmapsto -2x=12-9=3$

$\\ \rm\longmapsto x=\dfrac{3}{-2}=-1.5$
