A groundhog crawls out from a hole 3 feet below the surface of the ground. Joan wrote −3 feet to represent the depth from which the groundhog crawls out. What does 0 represent in this situation? the surface of the ground
the distance the groundhog crawled
the height above the surface of the ground
the level from which the groundhog crawled out

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

i can you with this question sweetie!

step-by-step explanation:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
