Will mark brainliest! Please help! The first four terms of a sequence are shown below:
9,5, 1, -3
Which of the following functions best defines this sequence? (5 points)
1) f(1) = 9, f(n + 1) = f(n) - 4; for n 2 1
2) f(1) = 9, f(n + 1) = f(n) + 4; for n 2 1
3) f(1) = 9, f(n + 1) = f(n) - 5; for n 2 1
4) f(1) = 9, f(n + 1) = f(n) + 5; for n 2 1

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

answer: 40392

step-by-step explanation:

10098 x 4 = 40392

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36
