Answer:
Step-by-step explanation:
First, as you can see, the sequence is alternating its sign everytime, so you can deduce this term:
The sequence start from 3, and the following terms are the product between 3 and . Take a look:
For n=1
For n=2
And so on...
Let's verify the formula including all terms:
Since the sequence start from 3, we must change the 3 for -3. Because is always negative for the first term:
For n=1
For n=2
For n=3
For n=4
So, one possible sequence is:
And the serie would be given by:
The elephant weighs 9,430 pounds more than the donkey.
Answer:
i dont knpw haha. sorry
Step-by-step explanation:
Look back at the rules of exponents.
(a^n)^d = a^(n×d)
Therefore,
(17^1/7)^7
=17^(1/7×7)
=17^(7/7)
=17^1 or 17
Hope I helped :)
Answer:

Step-by-step explanation:
(a)
For the graph to display direct proportion it must pass through the origin.
The graph shown does not pass through the origin thus does not represent direct proportion.
(b)
Given that q is directly proportional to r then the equation relating them is
q = kr ← k is the constant of proportion
To find k use the condition q = 76 when r = 20, thus
76 = 20k ( divide both sides by 20 )
3.8 = k
q = 3.8r ← equation of proportion
When r = 45, then
q = 3.8 × 45 = 171
