Adiver begins at 90 feet below sea level. she descends at a steady rate of 6 feet per minute for 6 minutes. then, she ascends 20 feet. this expression shows her current depth in feet. what is her current depth? feet feet feet feet

Her current depth is 106 feet below the sea level.

Step-by-step explanation:

Since we have given that

Distance a diver covered below sea level = 90 feet

Since it is below the sea level, so it will be written as (-) 90 feet.

After this, she descends at a steady rate of 6 feet per minute for 6 minutes.

So, Speed = 6 feet per minute

Time taken by him = 6  minutes

So, Distance covered =

Again she descends by 36 feet which is written as (-) 36 feet.

So, she reached at

Again, she ascends 20 feet.

Since she ascends by 20 feet then it will be written as (+)20 feet.

So, she reached at

Hence, her current depth is 106 feet below the sea level.

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
