The function f(x) = 2x + 210 represents the number of calories burned when exercising, where x is the number of hours spent exer
Alex787 [66]

This means 339 calories burned while combining diet with 1 hour of exercise

Step-by-step explanation:

Given the functions as:

f(x)=2x+210  

g(x)=2x+125 then

(f+g)(x) = 2x+210 +2x+125 = 4x +335

(f+g)(1) = 4(1)+335

           =339

This means 339 calories burned while combining diet with 1 hour of exercise

Find the 64th term of the arithmetic sequence
Margaret [11]

Answer:

The 64th term of the arithmetic sequence is -1075.

Step-by-step explanation:

Arithmetic sequence:

In an arithmetic sequence, the difference between consecutive terms, called common difference, is always the same.

The nth term of an arithmetic sequence is given by:

a_n = a_1 + (n-1)d

In which a_1 is the first term.

−4,−21,−38

First term -4, so a_1 = -4

Common difference of d = -38 - (-21) = -21 - (-4) = -17

Thus

a_n = a_1 + (n-1)d

a_n = -4 - 17(n-1)

Find the 64th term of the arithmetic sequence

This is a_{64}. So

a_n = -4 - 17(n-1)

a_{64} = -4 - 17(64-1) = -4 - 1071 = -1075

The 64th term of the arithmetic sequence is -1075.
