Suppose a town wants to design two landfills shaped as a cone and a cylinder. The base diameter and the volume of both designs will be the same. Which statement is true? A. The height of both designs are the same.
B. The height of the cylinder will be 3 times the height of the cone.
C. The height of the cone will be 3 times the height of the cylinder.
D. The volume cannot be the same when the bases have the same diameter.

34

step-by-step explanation:

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

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
