ASAP HELP ME PLZ IT IS FOR A GRADE

4189 [if you don't need pi in the answer]

1333 [if you do need pi in the answer]

Step-by-step explanation:

So the volume of a sphere is 4/3 * * radius^3

The radius of the sphere is 10.

4/3 10^3

4/3 1000

1333.33333

You never actually specified if you need to keep pi or not so here's both!

yes   because as the functions are graphed they eventually will intersect unless otherwise

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
