PLEASE HELP ME FFS

Mathematics
1 answer:
AnnZ [28]3 years ago
7 0

Answer:

55.74

Step-by-step explanation:

<em>Since the culture was tested and then the countdown started, you need to multiply the initial value by 3.5. Since it is tested once every 15 minutes, it will be tested two more times by the time 30 minutes is up; a total of 3 times tested.</em>

1.3 x 3.5 = 4.55

4.5 x 3.5 = 15.925

15.925 x 3.5 = 55.7375

16^3x+8^x+6<br><br>Could you please give me the steps as well for this problem? ​
BARSIC [14]

Answer:

x = 2

Step-by-step explanation:

16^{3x} = 8^{x+6} \\2^{4(3x)} = 2^{3(x+6)} --> (16 = 2^{4} and 8 = 2^{3} )

2^{12x} = 2^{3x+18}

Since the base number is 2, the exponents must equal each other.

So:

12x = 3x+18

9x = 18

x = 2

Find a formula for the inverse of the function. f(x)=1-2/x^3.
Elena-2011 [213]
       f(x) = 1 - ²/ₓ₃
          y = 1 - ²/ₓ₃
          y = 1 - ²/ₓ₃
      y - 1 = ⁻²/ₓ₃
      x - 1 = -2/y³
 y³(x - 1) = -2
         y³ = ⁻²/ₓ₋₁
          y = ∛⁻²/ₓ₋₁
          y = -∛(2x² - 4x + 2)/x - 1
      f⁻¹(x) = -∛(2x² - 4x + 2)/x - 1

If that’s not what you mean can you please elaborate to me!
