Ipatiy [6.2K]

Answer:

a_n = -11-14n

Step-by-step explanation:

Given

a_1 = -25

a_n = a_{n-1}-14

Required

The explicit formula

First, calculate a_2

Set n=2; So:

a_2 = a_{2-1}-14

a_2 = a_{1}-14

Substitute -25 for a_1

a_2 = -25-14

a_2 = -39

Calculate the common difference (d)

d = a_2 - a_1

d = -39 --25

d = -14

So, the nth term is:

a_n = a_1 + (n - 1)d

a_n = -25+ (n - 1)*-14

Open bracket

a_n = -25-14n + 14

Collect like terms

a_n = 14-25-14n

a_n = -11-14n

onyango wishes to fence a rectangular research plot using 100 m of wire .one end of the plot has a wall already erected .calcula
earnstyle [38]

Answer:

1250 m²

Step-by-step explanation:

Let x and y denote the sides of the rectangular research plot.

Thus, area is;

A = xy

Now, we are told that end of the plot already has an erected wall. This means we are left with 3 sides to work with.

Thus, if y is the erected wall, and we are using 100m wire for the remaining sides, it means;

2x + y = 100

Thus, y = 100 - 2x

Since A = xy

We have; A = x(100 - 2x)

A = 100x - 2x²

At maximum area, dA/dx = 0.thus;

dA/dx = 100 - 4x

-4x + 100 = 0

4x = 100

x = 100/4

x = 25

Let's confirm if it is maximum from d²A/dx²

d²A/dx² = -4. This is less than 0 and thus it's maximum.

Let's plug in 25 for x in the area equation;

A_max = 25(100 - 2(25))

A_max = 1250 m²
