Answer:
90 km/h
Step-by-step explanation:
To solve this problem you first need to convert minutes to hours since the unit is km/h. Doing this we get half an hour (1 hour=60 mins so you divide 30 by 60) after converting you simply divide 45 by 1/2 or .5 to get the answer.
Answer:
y=1x +8
5
Step-by-step explanation:
y-y1 = m(x-x1)
y+2 = -5(x-2)
y+2 = -5x + 10
y = -5x +8
Now to find line L we have to change the slope because it is perpendicular
y= 1x +8 (The slope is one fifth, but idk
5. to put it, I'm sorry)
A.) some irrational numbers are natural numbers.
1.30 represents the rate of growth of the mold spores. This decimal is a representation of the percentage growth, which would be 130%.
Since the function is written in terms of weeks, x will equal 4 to represent the amount of spores after 4 weeks. Plug the value into the function:

Rounded to the nearest ones value, there will be 985 mold spores after 4 weeks.
