Jillian walked 0.5 miles before she started jogging at an average pace of 5 miles per hour. The equation d=0.5+5t can be used to relate the total distance, d,in miles to the time ,t, that Jillian spend jogging what are the independent and dependent variables

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

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
