Answer:
density =
g/cm^3
Step-by-step explanation:
Step 1: Volume of soda can

=> 
volume = 4048.3
Step 2: Using answer from step 1 to calculate density

density = 
density =
g/cm^3
Answer:
Step-by-step explanation:
Using closest Wolfram|Alpha interpretation: P (7 4) P (6 3)
Assuming
"P"
is referring to prime numbers
|
Use as
instead
Input interpretation:
primes | between 28 and P(18)
Values:
2 | 3 | 5 | 7 | 11 | 13 | 17 | 19 | 23 (9 primes)
If x is the first integer, then x+1 is the second. x(x+1)=132 or x^2+x-132=0. This factors as (x-11)(x+12)=0. Thus either x=11 or x=-12
<span>So either 11 and 12 or -12 and -11 will do.</span>
Answer:
11r²-4r-3
Step-by-step explanation:
soo,, now firstly change the signs of 2nd expression
so,
9r²+5r-11+2r²-9r+8
now
we will combine the same terms like , see next step
9r²+2r²+5r-9r-11+8
11r²-4r-3
Let <em>a</em> be the first term in the sequence. If <em>r</em> is the ratio between consecutive terms, then the second term is <em>ar</em>, the third term is <em>ar </em>^2, the fourth is <em>ar</em> ^3, and so on, up to the <em>n</em>-th term <em>ar</em> ^(<em>n</em> - 1).
So the third, fourth, and fifth terms are such that
<em>ar</em> ^2 = 18
<em>ar</em> ^3 = 27
<em>ar</em> ^4 = 81/2
Solve for <em>a</em> and <em>r</em> :
(<em>ar</em> ^3) / (<em>ar</em> ^2) = 27/18 => <em>r</em> = 3/2
<em>ar</em> ^2 = <em>a</em> (3/2)^2 = 9/4 <em>a</em> = 18 => <em>a</em> = 8
Then the <em>n</em>-th term in the sequence is
<em>ar</em> ^(<em>n</em> - 1) = 9 (3/2)^(<em>n</em> - 1)
You can rewrite this by first rewriting 9 = 3^2, then
9 (3/2)^(<em>n</em> - 1) = 3^2 * 3^(<em>n</em> - 1) / 2^(<em>n</em> - 1) = 3^(<em>n</em> + 1)/2^(<em>n</em> - 1)
