The explicit rule for a sequence is given. an=4n−1 What is the recursive rule for the sequence?
Gnom [1K]

Answer:

a_{n+1}=a_n+4

Step-by-step explanation:

Have in mind the definition of the term a_n=4\,n-1, and now work on what the term a_{n+1} is based on the previous definition:

a_{n+1} = 4\,(n+1)-1\\a_{n+1}=4\,n+4-1

In the next step do NOT combine the numerical values, but try to identify the a_n term (4\,n-1) in the expression (notice the use of square brackets to group the relevant terms):

a_{n+1}=4\,n+4-1\\a_{n+1}=[4\,n-1]+4\\a_{n+1}=a_n+4

So now we have the term "a_{n+1}" defined in a recursive manner based on the previous term "a_n"

The cross section of a water bin is shaped like a trapezoid. The bases a a trapezoid are 20 feet and 6 feet long. It has a area
nekit [7.7K]

Answer:

the height of the cross section is 3 feet

Step-by-step explanation:

The computation of the height of the cross section is shown below:

Area = 1 ÷ 2 × (a + b) × h

39 = 1 ÷ 2 × (20 + 6) × h

39 =  1 ÷2 × 26 × h

39  = 26 ÷ 2 × h

39 = 13 × h

h = 39 ÷ 13

= 3 feet

hence, the height of the cross section is 3 feet
