for 7 & 8 you use the equation
your points are (3,8) & (9,5)
so you plug the numbers in
y2= 5
y1=8
x2=9
x1=3
you subtract them get a fraction and that is your slope
9 & 10
use the equation
plug you numbers in for y1 and x2 m is your slope plug it in and that is your equation

Using the shell method, the volume is given exactly by the definite integral,
Splitting up the interval [0, 1] into 5 subintervals gives the partition,
[0, 1/5], [1/5, 2/5], [2/5, 3/5], [3/5, 4/5], [4/5, 5]
with left and right endpoints, respectively, for the -th subinterval
where . The midpoint of each subinterval is
Then the Riemann sum approximating the integral above is
(compare to the actual value of the integral of about 14.45)
Answer:
He needs to sell 100 souvenirs
Step-by-step explanation:
We want to know the number of souveniers John has to sell
Let the number of souveniers he sold at the game be s
At a rate of $0.25 per souvenier, the amount earned on souveniers for s souveniers will be:
Now, if we added this to the amount he earns per game, we will have the total $35 earned for working at one game.
Thus, mathematically:
Answer:Remember that the general formula of geometric sequence is
where
is the nth term
is the difference
is the place of the term in the sequence
Also, to find we will use the formula:
where
is the current term in the sequence
is the previous term
a) Lets find the three first terms of our sequence to check what type of sequence we have:
We know for our problem that the initial value of the computer is $1250, so our first term is 1250. In other words .
To fin our second term , we are going to subtract 10% of the value to our original value:
and , so
To find our third term we are going to subtract yet again 10% to our current value:
and , so
Now that we have our sequence lets check if we have a consistent to prove we have a geometric sequence:
- with , and :
- with , and :
Look! our s are the same, so we can conclude that we have a geometric sequence.
b) To do this we just need to replece the values of our sequence in the general formula of a geometric sequence. We know from our previous point that and . So lets replace those values in geometric sequence formula to find our explicit formula:
c) To find the value of the computer at the beginning of the 6th year, we just need to find the 6th therm in our geometric sequence:
We can conclude that the value of the computer at the beginning of the 6th year will be $738.1125
