Tara goes skydiving and falls at a constant rate toward the ground. the equation y = -32x + 13,000 represents the situation where y is the height of tara in feet above the ground and x is the seconds since she jumped.

which statement describes the situation?

from a starting position of 13,000 ft above the ground, she is descending at 32 feet per second

from a starting position of 32 ft above the ground, she is ascending at 13,000 feet per second

from a starting position of 13,000 ft above the ground, she is ascending at 32 feet per second

from a starting position of 32 ft above the ground, she is descending at 13,000 feet per second

probably .5

i can on others if necessary.

the solution of the equation is 2.23 ⇒ answer b

step-by-step explanation:

* lets revise the meaning of exponential function

- the form of the exponential function is y = ab^x, where a ≠ 0, b > 0 ,  

  b ≠ 1, and x is any real number

- it has a constant base b

- it has a variable exponent x

- to solve an exponential equation, take the log or ln of both sides,  

  and solve for the variable

* lets solve the problem

∵

- the base is 7 and the exponent is x

- insert ㏑ in both sides

∴

- use the rule

∴ x ㏑(7) = ㏑(77)

- to find x divide both sides by ㏑(7)

∴

* the solution of the equation is 2.23 to the nearest 2 decimal places
