Note: enter your answer and show all the steps that you use to solve this problem in the space provided. solve the equation or formula for the indicated variable. t= 2 r π h + 2 π r ^2; for h

For this case we have the following equation:

We must solve the equation for the variable "h":

We subtract from both sides of the equation:

We divide by on both sides of the equation:

l.jnl.j/n.m,lm,

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
