ANSWER

The required equation is:

a_n=5(  - \frac{3}{5} )^{n-1}

EXPLANATION

The given sequence is

5, -3 ,  \frac{9}{5}

The first term of the sequence is ;

a_1=5

The common ratio is the subsequent term previous term of any two consecutive terms. This implies that;

r =  \frac{ - 3}{5}

The nth term of the sequence is

a_n=a_1(r)^{n-1}

We substitute the terms to obtain;

a_n=5(  - \frac{3}{5} )^{n-1}

The area of a trapezoid is 168cm2. The height is 16cm and the length of one of the parallel sides is 9cm. Find the length of the
dmitriy555 [2]

Answer:

12 cm

Step-by-step explanation:

The formula for the area of a trapezoid is written as:

1/2(b1 + b2)h

h = height = 16 cm

b1 = Length of one parallel side = 9cm

b2 = Length of second parallel side = ?

Area of trapezoid = 168cm²

The formula to find the length of the second parallel side =

b2 = 2A/h - b1

b2 = 2 × 168/16 - 9

b2 = 336/16 - 9

b2 = 21 - 9

b2 = 12cm

Therefore, the length of the second parallel side is 12 cm
