Answer:
x = 5
Step-by-step explanation:
Answer:
F = 0
Step-by-step explanation:
F(x) = 2 - 2
fx/3 = 0/x
f=0
answer: 39.3 feet
explanation:
- because you need to find the length of an arc, you should think about circumference. the formula for that is 2πr, where r is the length of the circle's radius.
- you don't need the whole circumference, though, so you'll need a fraction (in this case, it's 225/360, because 225° is the measure of the arc's angle and 360° is the measure of a full circle's rotation)
- multiply the circumference by this fraction to get the length of the arc.
work:
enter 12.5π into a calculator and it's about 39.3 after being rounded to the nearest tenth.
In an hour, she can write 3,750 words and in one minute she can write 62.5
22,500/5 = 3,750
3,750/60 = 62.5
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.
