Answer:
any coordinate outside the parabola is a reasonable answer.
Step-by-step explanation:
test the solution (0, 0) and if if that number is greater than 0 then the rest of the points outside on the inside are.
x = 0
y = 0
(0)^2 - 2(0) - 3 = -3
-3 is less than 0 so (0, 0) is not a possibility so any coordinate outside the parabola is a reasonable answer.
Answer:
Step-by-step explanation:
Solution,
The perimeter of a triangle=Sum of all sides
Hope it will help you a lot.
you will need to use the law of cosines since this picture does not indicate that this is a right triangle
c^2 = a^2 + b^2 – 2ab cos C,
16^2 = 17^2+8^2 -2*17*8*cosC
256=289-272cosC
-33=-272cosC
33/272 = cosC
cos^-1 (33/272)=C taking the inverse cos
C=83.0 (to the nearest tenth)
b^2 = a^2 + c^2 – 2ac cos B,
8^2 = 17^2 +16^2 -2*17*16cosB
64=289-544cosB
-225=-544cosB
225/544=cosB
cos^(-1) =B
B=65.5
A=180-83-65.6
A=31.4
Answer is B Mr James
Lets convert all the fractions, percentages to decimals:_
Mr James: 5/8 = 0.625
Miss Smith: 0.61
Mrs Lawson: 9/16 = 0.5625
Mr Tosh: 0.58
Mrs Cagle 0.53
So Mr James corrected the most homework.
