In regards to bacteria, which is true: a. it will not grow in cold temperatures (below 41 degrees) b. it will not grow in hot temperatures (greater than 135 degrees) c. it will grow rapidly in the danger zone (between 41 and 135 degrees) d. all of these

c. it will grow rapidly in the danger zone (between 41 and 135 degrees)

Explanation:

THe danger zone is what the food industry calls to a range of temperature that goes from 41-135 degrees in which bacteria grows exponentially more than in cooler or hotter temperatures, this creates a great environment for bacteria to reproduce, this is the only sentence that is correct, since bacteria can grow in exreme temperatures, above and below the danger zone but it just wont do it as fast.

c. 7/3

step-by-step explanation:

a rational number is like pi- it is a repeating decimal.

a. is -1.8

b. 2.236068

c. 2.3333333333333333333

d.   is 3

i hope that ! =)

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
