I assume that there should be a equal sign somewhere in here and if there is then the answer will look something like this r=5 if there is not then the answer would be 7r+35 the photo below should explain why.

9(r + 3) - ¹/₂(4r - 16)
9(r) + 9(3) - ¹/₂(4r) + ¹/₂(16)
9r + 27 - 2r + 8
9r - 2r + 27 + 8
7r + 35

How do i find the first term of a geometric sequence when i know a3= 1/8 and a6= 1 ?

ale4655 [162]

Answer:

Step-by-step explanation:

nth term = ar^(n-1)

a3 = 1/8; ar² = 1/8

a6 = 1; ar⁵ = 1

$ar^{2}*r^{3}=1\\\\\frac{1}{8}*r^{3}=1\\\\r^{3}=1*8\\\\r^{3}=8\\\\r^{3}=2^{3}\\\\r=2$

$ar^{2}=\frac{1}{8}\\\\a*2^{2}=\frac{1}{8}\\\\a*4=\frac{1}{8}\\\\a=\frac{1}{8*4}\\\\a=\frac{1}{32}\\\\$

M is the midpoint of AB. Find the coordinates of B given A(3,8) and M(5,4).

Harlamova29_29 [7]

Answer: B(7,0)

Step-by-step explanation:

Since coordinate of A(3,8) and M(5,4), where M is the midpoint of AB.

Let the coordinate of B be (x,y)

Therefore, the distance AM is equal to distance MB.

Distance = sqrt{ (5 - 3)² + (4-8)² } =sqrt { (x-5)² + (y-4)²}

Comparing corresponding coordinates,

5-3 = x-5

x= 5+5-3 = 7

4-8 = y-4

y= 4-8+4= 0

Therefore, the coordinate of B is (7,0)
