Answer:
Graph B
Step-by-step explanation:
the line is at some point perpendicular to the y-axis, there is no unique y value for this x value, which contradicts the definition of a function.
Answer:
70 hours
Step-by-step explanation:
3500 by 50 is 70
Answer:
real:√2, 3,-1, 1/2 etc
natural: 1,2,3,4,5,6.....(0 is not included)
integers:. .............-4,-3,-2,-1,0,1,2,3,4........ etc
rational: nos. which are in p/q form
:1/2,3/4,4/9 etc
irrational: nos. which cannot be written in p/q form
: √2,√3... etc
irrational: √2, √3, √5, √11, √21, π(Pi)
(-1,-2) and (-1,4)
so these have same x values, but different y values, so these are on differnt sidef of circle
distanc between them is 6
6/2=3
radius=3
so move 3 units up from (-1,-2)
(-1,1)
so
if center is (h,k) and radius is r then
(x-h)^2+(y-k)^2=r^2
(-1,1) is center and r=3
(x-(-1))^2+(y-1)^2=3^2
(x+1)^2+(y-1)^2=9
Answer:
y = (1/2) cos (x)
Step-by-step explanation:
It has the same period as cos x but only goes half as high and half as low. Normalyy, cos(x) goes up to 1 and down to -1.
