Three more than twice the number is 25
The number you're looking for is 25. Simply work backwards.
25 - 3 (three more...) = 22
22 ÷ 2 (twice the number) = 11
Answer:
c a(n+10)
Step-by-step explanation:
[(-1)^(n+1)] × (5^n)
an > 0
a(n+5) = (-1)⁵ × 5^(n+5) < 0
a(n+10) = (-1)¹⁰ × 5^(n+10) > 0
a(n+15) = (-1)¹⁵ × 5^(n+15) < 0
Since a^n is positive, n is even
Odd powers of -1 are negative
Answer:
first graph option A
Step-by-step explanation:
Rule is y= 2x
Lets make a table to find out some point for graphing
Plug in some values for x and find out y
x y= 2x
-2 y=2(-2) = -4
0 y= 2(0)=0
2 y = 2(2)= 4
So the coordinates for graphing are (-2,-4) , (0,0) and (2,4)
The first graph has all the same coordinates .
So first graph represents the same relation
The distance is 52.5 cm when weight is 7kg
Step-by-step explanation:
Distance is 15 cm when weight is 2 kg
We need to find the distance d when weight is 7 kg
Since distance and weight varies directly so,
Solving the above expression:
So, The distance is 52.5 cm when weight is 7kg
