a pool is 10 meters long and 8 meters wide. if you place flower pots around the pool 1 meter apart, center to center, how many flower pots do you need? (there should be a flower pot at each corner of the pool.)

18 pots.

Step-by-step explanation:

10/2 to get one of the longs. 5(2) to get the other one. 10.

8/4 to get one of the wides. 2(2) to get the other one. 4.

There are 4 corners so there are 4 extra pots. 4.

Add the numbers: 4+4+10. 18

18 pots.

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
