Answer:
2
Step by step:
1•2=2
2•2=4
3•3=6
And so on...
Hope this helps!!
U= 9.4m/s
v= -7.4m/s (Negative sign because it is in the opposite direction as he is rolling back)
t= ?
s= ?
a= ?
Now, a= v-u/t
= -7.4-9.4÷3
=-5.6
By the second equation of motion.
s= ut+1÷2at*2 ( *2 is the power)
s= 9.4×3+1÷2×-5.6×3*2
= 28.2 +(-25.2)
=3
Therefore s or the distance travelled is 3m.
Answer:
y-2=3(x+6)
Step-by-step explanation:
you place the axis y and the x in the proper form; y - y1 = 3 ( x - x2)
since axis x is a negative, and in the slope form it is in need of a subtraction, you reverse it; a positive number.
Answer:
a) 9r=63
b) 14 mi/h
Step-by-step explanation:
Let say r the speed of the slower cyclist,
2*r the speed of the faster cyclist,
they meet 3 hours later:
a)
<u> (r+2*r)*3=63 </u>
3r*3=63
9r=63
r= 63/9
r=7 (mi/h)
b)
<u>2r=14 (mi/h)</u>
Answer:
0.5
Step-by-step explanation:
-20 and -40
quotient means divide one another
-20 / -40
= 20/40
= 2/4
= 0.5
I made these into tiny tiny steps, enjoy.
