Write the explicit formula that represents the geometric sequence -2, 8, -32, 128
Jet001 [13]

The Geometric Sequence Formula:

a_n=a_1r^{n-1}

We have:

a_1=-2,\ a_2=8,\ a_3=-32,\ a_4=128,\ ...

d=\dfrac{a_{n+1}}{a_n}\to d=\dfrac{8}{-2}=-4

Substitute:

a_n=-22\cdot(-4)^{n-1}=-22\cdot(-4)^n\cdot(-4)^{-1}=-22\cdot(-4)^n\cdot\left(-\dfrac{1}{4}\right)=5.5(-4)^n

Write an equation for the line that passes through (-8.5, 11) and (5, -2.5).
max2010maxim [7]

9514 1404 393

Answer:

  y = -x + 5/2

Step-by-step explanation:

The 2-point form of the equation of a line can be useful.

  y = (y2 -y1)/(x2 -x1)/(x -x1) +y1

  y = (-2.5 -11)/(5 -(-8.5))/(x -(-8.5)) + 11

  y = -13.5/13.5(x +8.5) +11 . . . . . . simplify a bit

  y = -x +2.5 . . . . . write in slope-intercept form

A landscape designer has to construct a rectangular flower bed with a perimeter of 100 feet and the maximum possible area. What
Alinara [238K]

9514 1404 393

Answer:

   625 square feet

Step-by-step explanation:

The greatest area of a polygon with a given perimeter is that of a regular polygon. A regular rectangle is one that has all sides the same length -- a square. The side length of a square with 100 ft perimeter is 25 ft. The area of a square with such a side length is

  A = (25 ft)² = 625 ft²

The maximum possible area is 625 ft².

__

In the attached, x is the length of one side. The area versus side length is plotted. The maximum is seen to be 625 ft² for a side length of 25 ft.
