Answer:
None.
Step-by-step explanation:
The coefficients are a=1, b=-3, c=8, so the discriminant is ...
... b²-4ac = (-3)²-4(1)(8) = 9-32 = -23
This negative value means both the roots are complex.
Answer:
(-6,3)
Step-by-step explanation:
In this problem, an angle like angle BAC where the
vertices like on the circle itself is called the inscribed angle.
While angle BOC, where O is the center of the circle, is
called the central angle.
Using Proposition III.20 from Euclid's Elements, this is called
the Inscribed Angle Theorem wherein:
∠BOC = 2∠BAC
or ∠BOC / 2 = ∠<span>BAC</span>
Answer:
78.75
Step-by-step explanation:
450 is increased by 75%
450 + 450*75%
Change to decimal form
450 +450*.75
450+337.5
787.5
Now decrease by 90%
787.5-787.5*90%
Change to decimal form
787.5-787.5*.9
787.5-708.75
78.75
