true a segment has a finite length and to determent endpoints
Answer:
y-interspet i think
Step-by-step explanation:
∠VUR and ∠QRU are alternate interior angles, the line that links them is Z-shaped, which means that these angles are equal, so that:
Answer:
f(x) = 7/(x+3) -38/(x+3)²
Step-by-step explanation:
The denominator is a perfect square, so the decomposition to fractions will involve both a linear denominator and a quadratic denominator.
You can start with the form ...
... f(x) = B/(x+3) + A/(x+3)²
and write this sum as ...
... f(x) = (Bx +3B +A)/(x+3)²
Equating coefficients gives ...
... Bx = 7x . . . . . B = 7
... 3B +A = -17 . . . . the constant term
... 21 +A = -17 . . . . filling in the value of B
... A = -38 . . . . . . . subtract 21 to find A
Now, we know ...
... f(x) = 7/(x+3) -38/(x+3)²
Let us say that t is number of months and n is the number
of cases of Bangkok flu, therefore the equation we can create here is:
dn / dt = 10 t + 450
<span>where 10 represents the slope and 450 represents the
y-intercept</span>
