2 seperate questions
what is the weight of 1 gallon and what is the cost per gallon
weight/1gallon=wieght/gallons=129.8lb/22gal=5.9lb/1gal
weigth is 5.9lb per gallon
cost per gallon=cost/gallons=$91.30/22gal=$4.15/1gal
cost is $4.15 per gallon
if ya wanted to estimate
lb per gallon is 129.8lb/22gal≈130/20=6.5lb/gal=6.5lb per gal
cost is $91.30/22gal ≈90/20=9/2=$4.50 per gal
No,
is not a subspace of
because it doesn't contain the zero vector.
Answer:
C) 6x+2
Step-by-step explanation:
if you multiply 6 by all the x factors and add 2 you get the y factors
Answer:
Step-by-step explanation:
Assuming the complete question :"It took 16 seconds for a mercury thermometer to rise from -4C degrees to 100C degrees when it was taken from a freezer and placed in boiling water. Show that somewhere along the way the mercury was rising at the rate of 6.5degreesC/second.
"
For this case we can find the rate of change like this:
For this cas we have the following data:
represent the initial temperature
represent the final temperature
we assume that we star at 0 seconds
represent the final time
So we can replace the info and we got:
And that satisfy the proof.
