Step-by-step explanation:
Given formula
an = n² + 4
Now the first four terms of the sequence are
a1 = 1² + 4 = 5
a2 = 2² + 4 = 4 + 4 = 8
a3 = 3² + 4 = 9 + 4 = 13
a4 = 4² + 4 = 16 + 4 = 20
The terms are
5 , 8 , 13 and 20.
Answer:
-3
Step-by-step explanation:
Option A: d(t) = 360-60t is the right answer
Step-by-step explanation:
We will write the given problem in terms of function to find the correct answer.
Let d(t) be the function and t be the number of hours.
Total distance is 360 miles and with each passing hour the distance will reduce 60 miles
So,
The function is:
Hence,
Option A: d(t) = 360-60t is the right answer

Answer:
b=1
Step-by-step explanation:
6*1=6
6*8=48
2x + 2x+2 = -134
4x + 2 = -134
4x = -136 |: 4
x = -34
2x = 2 * (-34) = -68
2x + 2 = -68 + 2 = -66
This numbers are -66 and -68.
