Answer:
1416.925 km cubed
Step-by-step explanation:
v = 3.14 x (9.5 squared) x 5
v = 1416.925
Answer:
1
Step-by-step explanation:
The function with the given zeros will factor as ...
f(x) = a(x +15)(x^2 +9) . . . . with leading coefficient 'a'
You have ...
f(2) = 221 = a(2+15)(2^2+9) = a(17)(13) = 221a
Then a = 221/221 = 1
The leading coefficient is 1.

<em>Additional comment</em>
As you know, a function with zero x=p has a factor of (x -p). The given zeros mean the function has factors (x -(-15)), (x -3i). and (x -(-3i)). The product of the last two factors is the difference of squares: (x^2 -(3i)^2) = (x^2 -(-9)) = (x^2 +9). This is how we arrived at the factorization shown above.
Answer:
4x-111
Step-by-step explanation:
let 'my number' be 'x'
x-15 -> (subtract from x)
4(x-15) -> (multiply result from (x-15) by 4)
4(x-15) - 51 -> (subtract 51 from result from [4(x-15)])
4x-60-51
4x-111
This is the expression for the number
