Mathematics
1 answer:
kirza4 [7]3 years ago
8 0

Answer:

(k + 9)(k - 8)

Step-by-step explanation:

Given

k² + k - 72

Consider the factors of the constant term ( - 72) which sum to give the coefficient of the k- term ( + 1)

The factors are + 9 and - 8, since

9 × - 8 = - 72 and 9 + 8 = + 1, hence

k² + k - 72 = (k + 9)(k - 8)

An E. coli bacterium has a diameter of about 5×10^-7 meter. Write this measurement as a decimal in standard notation. Explain .
Archy [21]
5<span>×</span>10^-7 = 0.0000005 
When 10 is to a negative power, you move the decimal to the left because the number is less than positive 1. Here 10 is to the power of -7, so you move the decimal (which is after/behind 5) to the left 7 times.
