Wilson has already prepared 2 kilograms of dough and will continue preparing 1 kilogram of
dough every hour. how much dough did wilson prepare if he worked for 4 hours?

6 kilograms

Step-by-step explanation:

He starts with 2.

He makes 1 every hour.

He works for 4 hours.

So, we can infer that he makes 4 kilograms within the 4 hours he works. Then, we see that he has already made 2 kilograms. So, you add up those two, giving you 6. Hope this helps!

it’s the first one your welcome

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
