In trevor's biology class, the students tested for bacteria on a kitchen sponge. they found that there were approximately 17,000,000 bacterial colonies on a single sponge. express their findings in scientific notation. 17 × 106 1.7 × 106 1.7 × 107 0.17 × 108

a - base

b - exponent

so,

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
