The leopard population in an African wildlife area is currently 17. Due to a new conservation effort, conservationists hope the
kykrilka [37]

Answer:

a{_n} = 17 + (n - 1)4 for n = 1, 2, . . . , 20.

Step-by-step explanation:

This is an arithmetic sequence, because the population is said to increase by 4 animals yearly. The formula for the nth term in an arithmetic sequence is given by:

a{_n} = a{_1} + (n - 1)d where a_n is the nth term, [/tex]a_1[/tex] is the first term, n = 1, 2, . . . and d is the common difference.

Since they are currently 17, this implies that the first number in the population sequence will be 17. In order words, the first term is 17.

Since they increase by 4 yearly, then the common difference is 4.

Since it's for 20years, the n = 1, 2, . . ., 20. The explicit formula is therefore:

a{_n} = 17 + (n - 1)4 for n = 1, 2, . . . , 20.

Given the function g(x) = 8x − 2, compare and contrast g(−2) and g(4). Choose the statement that is true concerning these two va
kramer

Answer:

The value of g(−2) is smaller than the value of g(4).

Step-by-step explanation:

To solve this, simply plug in the values in the given equation g(x)=8x-2.

g(-2)=8(-2)-2  -----> -18

g(4)=8(4)-2   ------> 30

here it is obvious that -18 is smaller than 30, therefore the value of g(−2) is smaller than the value of g(4).
