Answer:
50
Step-by-step explanation:
your expression: 2j²
plug in j = 5: 2(5)²
solve for the exponent: 2(25)
multiply: 50
5 is 25 percent of 20. 5 times 4 is 20. 100 divided by 4 is 25.
The value of asked for is obtained by subtracting the distance traveled downward by the climber from the peak elevation. This is shown below,
d = 14,090 ft - 490 ft
The value is equal to 13600 ft. Thus, the climber is 13,600 ft from the ground.
