For now I don't know the answer to this problem of yours.
Answer:
6561 / 128
Step-by-step explanation:
The nth term of a geometric sequence is:
a = a₁ (r)ⁿ⁻¹
The first term is 3, and the fourth term is 81/8.
81/8 = 3 (r)⁴⁻¹
27/8 = r³
r = 3/2
The eighth term is therefore:
a = 3 (3/2)⁸⁻¹
a = 6561 / 128
Answer:
4y + 48 - 16x = 0 ~Solve for y~
4y = -48 + 16x
y = -12 + 4x
The slope is 4.
We'll use the point (1, 4) and m = 4.
Plug these into the equation: y - y1 = m(x - x1)
y - 4 = 4(x - 1)
y - 4 = 4x - 4
y = 4x
Use the Pythagoras Theorem in the corresponding right angled triangles.
