Mathematics

we know that

The measure of <u>the interior angle</u> is the semi-sum of the arcs comprising it and its opposite.

so

Angle\ XYZ=\frac{1}{2}[arc\ UW+arc\ XZ]

In this problem we have

arc\ UW=110\°

arc\ XZ=42\°

substitute the values

Angle\ XYZ=\frac{1}{2}[110\°+42\°]

therefore

the answer is the option B

\frac{1}{2}[110\°+42\°]

Factor of x^3-x^2-24x-36
Basile [38]
The trial and error method is used to find an initial factor:
If we let f(x) = x³ - x² - 24x - 36 and all we have to do is sub' in values of x until
f(x) = 0, we can use this to find an initial factor by the factor theorem:
f(1) = (1)³ - (1)² - 24(1) - 36 = -60
f(2) = (2)³ - (2)² - 24(2) - 36 = -80
f(5) = (5)³ - (5)² - 24(5) - 36 = -56
*** f(6) = (6)³ - (6)² - 24(6) - 36 = 0 ***

f(6) = 0 so (x - 6) is a factor of f(x).
This means that: f(x) = x³ - x² - 24x - 36 = (x - 6)(ax² + bx + c).
To find a,b and c, use long division (or inspection) to divide x³ - x² - 24x - 36 by x - 6.
The other 2 factors of f(x) can then be found by factorizing the
ax² + bx + c quadratic the way you would with any other quadratic (i.e. by quadratic formula, CTS or inspection).

the time it takes to fly from los angeles to new york varies inversely as the speed of the plane. if the trip takes 6 hours at 9
natima [27]
Inverse variation means y=k/x  (direct variation is y=kx) so we can use the info given to find the constant k

y=k/x

6=k/900

k=6(900)

k=5400 so the equation is:

y=5400/x  or more accurately for this problem

t(v)=5400/v  then:

t(800)=5400/800

t(800)=6.75 hours
