Larissa argued that since log2(2) = 1 and log2(4) = 2, then it must be true that log2(3) = 1.5. is she correct?
explain how you know.

. This means that Larissa is not correct.

Step-by-step explanation:

To solve logarithms, we have to consider the following:

= c means that .

So, for example:

because .

because .

If , then Larissa is correct. However, . This means that Larissa is not correct.

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
