over the week the daily low temputures in degrees Fahrenheit have been -4, 6.2, 18 1/2, -5.9, 21, -1/4, and 1.75. list these numbers in order from least to greatest
we have that
1/2=0.5
1/4=0.25
so
order from least to greatest
<h2>-5.9,-4,-1/4,1/2,1.75,6.2,18,21</h2>
Answer:
It'll take 12 minutes to be at 30 degrees.
Step-by-step explanation:
Since the metal is cooling at a linear rate then the rate of degrees per minute should be the through the cooling process. From 4 minutes to 7 minutes there was a span of 3 minutes and in that time the metal cooled 105 degrees. So the metal is cooling at a rate of
rate = 105/3 degrees/minute = 35 degrees/min
To reach 30 degrees from 205 it should cool down an additional 175 degrees so it'll take:
minutes = deegrees/rate = 175/(35) = 5 minutes
Since the metal had a temperature of 205 degrees in 7 minutes, then it'll take 12 minutes to be at 30 degrees.
Answer:1700
Step-by-step explanation:
Answer:
y=x^2-2x+1 is matched to the second graph
Y=x^2-2x is matched to the third graph
Y=2x^2+4 is matched to the first graph
Well if you use graph paper you can graph the points you already have and then you can find the slope of the line easiest that way, the next point would be. (-1,8)
