If r is a region in the xy plane, then what does rr r 1 da represent geometrically? there are at least two possible answers. if e is a solid in space, then what does rrr e 1 dv represent geometrically?

their is no graph showing

step-by-step explanation:

with btw u said 100pts but it clearly says

i answerd and just got 10pts

no hate

answer: -0.5 would be the most likley outcome

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
