Let x or y be 0
4x-2y=5
4(0)-2y=5
-2y=5
Divide -2 and 5 by -2.
y=-2.5
4x-2y=5
4x-2(0)=5
4x=5
Divide 4 and 5 by 4.
x=1.25
I did not check my math, feel free to correct me.
Ok, base area: triangle sides are 25cm each, or .25m
s=semiperimeter
area=s(sqrt(s-side)^3)
s=75/2
s-side=37.5-25=12.5
area=37.5*12.5*sqrt12.5
let E6 mean 10^6
.075E6m=1/3 (37.5*12.5*(sqrt12.5))h
solve for h
I get:137cm
I hope that helped
Answer:
The slope is the percentage of test score per number of days absent
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
we have
y -----> is the percentage of test score
x ----> is the number of days absent
so
That means -----> The slope is the percentage of test score per number of days absent
In this problem the slope is negative
so
If the percentage test score increases----> the number of days decreases
If the percentage test score decreases----> the number of days increases
Let
. Then
and
are two fundamental, linearly independent solution that satisfy
Note that
, so that
. Adding
doesn't change this, since
.
So if we suppose
then substituting
would give
To make sure everything cancels out, multiply the second degree term by
, so that
Then if
, we get
as desired. So one possible ODE would be
