Hello :
hello :
the nth term is : An=A1×r^(n-1)
<span>The first term of the sequence is 0.01
r =An/an-1 =20
</span><span>An =0.01(20)^n-1...(answer :D )
</span>
I guess he needs to save $4 more to buy the shoes
Assuming the order does not matter, you want the number of combinations of 9 things taken 5 at a time. The combinations can be shown as C(9,5), 9C5.
C(9, 5) =
9/5(9-5) =
9*8*7*6*5 / 5*4
The 5 terms cancel.
9*8*7*6 / 4*3*2 =
9*7*2 =
126
The above change is because 4*2 cancels the 8 in the numerator and 6/3 = 2
Therefore, the solution is 126.
The solution is x=-4, y=-2
Answer:
-12
Step-by-step explanation:
-8 * ( 1/4) * (6)
= -12
