I need help with the following question. What is the capacity of a 3 cubic foot carton in cubic inches?

  5184 in³

Step-by-step explanation:

A cubic foot is (12 in)³ = 1728 in³, so 3 of them is ...

  3 × 1728 in³ = 5184 in³ . . . . capacity of a 3 ft³ carton

answer: 323 is how many she has ☃☃⛄❄

step-by-step explanation:

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
