Answer:
{(-6, -9), (-6,4),(-1,9), (5, -1)}
Explanation:
because the x value is not repeated twice as it is in {(-8, -2), (7, -2),(-9,2), (0,0) {(5,8), (9,7),(-3,-8),(5,-5)} {(7,-8), (7, - 7), (8,4),(1, -3)}
The second one is a function. {(-8, -2), (7, -2),(-9,2), (0,0)
Its because the y-value is repeated twice.
Hope it helps.
A
100s:160 paces
50s: 80 paces
80*0.80= 64
a transverse (sort of a plot of a sine or cosine graph, basically)
b longitudinal
c Electromagnetic (an electric wave and a magnetic wave travelling together at right angles to each other)
b
just took the test
Explanation:you know
circumference of a circle =2*pi*r=?
r=radius of a circle =3m
total distance of 6 revolution =s=6*2*pi*r
again, linear speed =v=s/t=?
t=time =60sec
