Answer
Since the lyla deleted it actually for a good reason let me explain. But you dont just delete random answers, you can give a comment. I can report you for doing that.
So since it burns at 1.3 per hour. Notice that since it gets removed per hour. so it would be 1.3t so it multiplies per hour. Then we need to subtract. Thats because it lowers the length of the candle. So we get the original length - 17 and get the function
f(t) = 17-1.3t
Answer:
180 min
Step-by-step explanation:
The first thing is to get the number of days in two weeks that he would read the book, since he only does it when he goes to school. School goes from Monday to Friday, that is to say 5 days, how two is two weeks would be a total of 10 days. Mathematically, it would be the equation, where X would be the number of minutes inside the parentheses and the minutes read before and after school:
X = 10 * (10 + 8)
Solving:
X = 180
In other words, in two weeks he has read a total of 180 minutes.
Answer:
For t=3 sec the velocity change from positive to negative
Step-by-step explanation:
we have
This is the equation of a vertical parabola open downward (the leading coefficient is negative)
where
s(t) is the distance in feet
t is the time in seconds
We know that
To find out when the velocity change from positive to negative, we need to determine the turning point of the quadratic equation
The turning point of the quadratic equation is the vertex
so
Convert the quadratic equation into vertex form
Factor -16
Complete the square
Rewrite as perfect squares
The vertex is the point (3,244)
therefore
For t=3 sec the velocity change from positive to negative
Answer:
32 divided (10-8) divided by 2-3
