Answer:
(a) (-12/13, 5/13)
(b) (12/13, -5/13)
(c) (-12/13, -5/13)
(d) (12/13, 5/13)
Step-by-step explanation:
(a) The terminal point is effectively reflected across the y-axis, so the sign of the x-coordinate changes. (-12/13, 5/13)
__
(b) The terminal point is effectively reflected across the x-axis, so the sign of the y-coordinate changes. (12/13, -5/13)
__
(c) The terminal point is effectively reflected across the origin, so the signs of both coordinates change. (-12/13, -5/13)
__
(d) The terminal point is mapped to itself, so its coordinates remain unchanged. (12/13, 5/13)
First we find the factors
a^3-8 is the differnce between 2 perfect cubes and is factored out to
(a-2)(a^2+2a+4)
the factors are (a-2) and (a^2+2a+4)
a^4+16
this is not factorable, unless you mistiped it and it was really a^4-16
the factor is 1
a^3+2a^2+4a
factor out the a
a(a^2+2a+4)
this is the most factored out form
the factors are (a) and (a^2+2a+4)
there are no common factors except 1 so 1 is the answer
Answer:
35% chance
Step-by-step explanation:
add up total number of marbles 4+6+3+7= 20
add up number of red and yellow marbles 4+3= 7
there is a 7 out of 20 chance that a red or yellow marble is chosen or in other words 35% chance
