How would i solve this problem using log base 10

Mathematics

Archy [21]3 years ago
8 0

First isolate the power of 10 on the right side by dividing both sides by 5:

100=5\cdot10^{0.3t}\implies20=10^{0.3t}

Now you're free to take the logarithm and simplify where you can:

\log_{10}20=\log_{10}10^{0.3t}=0.3t\log_{10}10=0.3t

Then solve for t:

t=\dfrac{\log_{10}20}{0.3}\approx4.34

Which set of numbers could represent the side lengths of a right triangle?
sveticcg [70]

Answer:  D) 8, 15, 17

<u>Step-by-step explanation:</u>

In order for three side lengths to represent a right triangle, they must satisfy the Pythagorean Theorem: a² + b² = c²    where c is the largest side.

A) 2² + 3² = 4²

   4  +  9   = 16      

       13      = 16      FALSE

B) 4² + 5² = 6²

  16  + 25 = 36

       41     = 36       FALSE

C) 6² + 9² = 12²

   36 + 81 = 144

       117    = 144       FALSE

D) 8² + 15² = 17²

  64 + 225 = 289

       289    = 289     TRUE!
