Split up the interval [2, 5] into
equally spaced subintervals, then consider the value of
at the right endpoint of each subinterval.
The length of the interval is
, so the length of each subinterval would be
. This means the first rectangle's height would be taken to be
when
, so that the height is
, and its base would have length
. So the area under
over the first subinterval is
.
Continuing in this fashion, the area under
over the
th subinterval is approximated by
, and so the Riemann approximation to the definite integral is
and its value is given exactly by taking
. So the answer is D (and the value of the integral is exactly 39).
Let us assume then that the center is the origin. If the major axis is 18, then a = 9 and a^2=81. If the minor axis is 16, then b = 8 and b^2=64. Now you can write the equation. Remember that this ellipse is vertical and so a^2 goes under y^2
Answer:
y=mx+b is slope-intercept form
Ax+By=C is standard form.
IN y=mx+b, m represents the slope and B represents the y intercept.
To switch from standard form to slope-intercept form all we need to do is get y alone. thats it. By folowing these steps:
-6x+5y=-30
-6x+6x+5y=-30+6x - this cancels the x on the left side of the equation bringing us one step closer to getting y alone
5y=-30+6x
5y / 5=(-30+6x) / 5 -this last step leaves y alone and brings us to slope intercept form.
y=-6+30x
y=30x-6 - i switched the 30x and 6 because y=mx+b not y=b+mx
y=30x-6
SInce m represents the slope and b represents the y itnercept, 30 is the slope and -6 is the y intercept
30=m(slope)
-6=b(y-intercept)
Btw because the slope is 30 it means the line with point like so: / since it has a positive slope.
