Question

A fish is hovering at –320 feet in relation to sea level. Then it descends 2 feet per second for 8 seconds. Brenda says that the new position of the fish in relation to sea level is represented by the equation below.

2 times 8 + (negative 320) = 336

Which explains whether Brenda is correct?
pls help

Answer 1

Brenda is not correct.

Explanation:

Brenda's equation for the new position of the fish in relation to sea level is:

2 times 8 + (negative 320) = 16 - 320 = -304

This means that the fish has descended 2 feet per second for 8 seconds, which is a total descent of 16 feet, and is now at a depth of -304 feet in relation to sea level.

Therefore, Brenda's equation is not correct. The correct equation should be:

new position = initial position - descent

where "initial position" is the starting position of the fish (which is -320 feet in this case), and "descent" is the total distance the fish has descended (which is 2 feet per second x 8 seconds = 16 feet in this case).

Using this formula, we get:

new position = -320 - 16 = -336

So the new position of the fish in relation to sea level is -336 feet, not 336 feet as Brenda's equation suggests.

Therefore, Brenda is not correct.
