Answer:
8.e+21
Step-by-step explanation:
Answer:
16 (D)
Step-by-step explanation:
(-1/2) = -0.5
-0.5^-4 = 16
The answer is A. Two times two is four, and four plus seven (3.5 times 2) is eleven.
Answer:
w = 54°
Step-by-step explanation:
w is the inscribed angle subtended on the same arc with measure of 108°
w is half the size of the central angle, that is
w = 0.5 × 108° = 54°
The easiest ways is to use the quadratic formula that is:
x' = [-b+√(b² - 4ac)]/2a and x" = [-b -√(b² - 4ac)]/2a
Solving : 2x² + 5x - 11 = 0, gives:
x' = [-5+√(25 - 4(2)(-11)]/4 and x" = [-5-√(25 - 4(2)(-11)]/4
x' = (-5+√113)/4 & x" = (-5-√113)/4
