We can rewrite this by subtracting the right side to get

... 3^(-x) -x^3 -x = 0

A graphing calculator shows this to have a solution near x=0.5.

_____

There are no algebraic means for solving such a combination of exponential and polynomial functions.

Answer:

6200

Step-by-step explanation:

first find how much she would make purely based on hours worked:

8x40 = 320 dollars

next subtract this from total on her paycheck so 692-320 is 372

we know that 372 is 6% of a number so...

$\frac{6}{100}$ x = 372

$\frac{6x}{100}$ = 372

6x= 37200(100)

x=6200 $ divide by 6

so she sold $6200 worth of merchandise to earn $372 of commission

Step-by-step explanation:

sin theta is equal to perpendicular by hypotenuse

here perpendicular is equal to 15 and base is equal to 8 therefore hypotenuse will be equal to 17

on putting on putting the value of perpendicular by hypotenuse we get 15 by 17 as sin theta
