Answer: 39ft²

Option 1: A= a+b/2 (h)

Trapezoid 1:

8+5/2(3)

13/2(3)

6.5*3

=19.5

Trapezoid 2:

9+4/2(3)

13/2(3)

6.5*3

=19.5

Now add both areas together

19.5 + 19.5 = 39ft²

Option 2: A= a+b/2(h)

Work both trapezoids at the same time

Base 1: top of trapezoids: 5 +4= 9ft

Base 2: Bottom of trapezoids: 8+9=17ft

Height is 3ft

A=9+17/2(3)

26/2(3)

13(3)

A=39ft²

Hope that this helps you.

Find the 6th term of a geometric sequence with t1=5 and r = -1/2
Hoochie [10]
In this item, we are to calculated for the 6th term of the geometric sequence given the initial value and the common ratio. This can be calculated through the equation,
   
                 An = (A₀)(r)ⁿ ⁻ ¹ 
where An is the nth term, A₀ is the first term (in this item is referred to as t₀), r is the common ratio, and n is the number of terms. 

Substitute the known values to the equation,

                   An = (5)(-1/2)⁶ ⁻ ¹
                   An = -5/32

Hence, the answer to this item is the third choice, -5/32.
