(01.01 MC)Which number line shows the solution to 3 + (−3)? A: A number line from 3 to 0 is shown. B: A number line from -3 to 3 is shown C: A number line from 3 to 6 is shown D: A number line from -3 to 6

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

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
