Answer:
15 kg
Step-by-step explanation:
Radius of a solid sphere : mass of a solid sphere
3 cm : 9 kg
Find the mass of a sphere of the same material of radius 5 cm
Radius of a solid sphere : mass of a solid sphere
5 cm : x kg
Equate both ratios to find x
3 cm : 9 kg = 5 cm : x kg
3/9 = 5/x
3 * x = 9 * 5
3x = 45
x = 45/3
x = 15 kg
The mass of a sphere of the same material of radius 5 cm is 15 kg
Answer:
(a) 3 must be factored from 3x^2 + 9x
Step-by-step explanation:
The first step when rewriting a quadratic from standard form to vertex form is to factor out the leading coefficient from the variable terms.
__
y = 3x^2 +9x -18 . . . . . . given
y = 3(x^2 +3x) -18 . . . . . leading coefficient factored out
y = 3(x^2 +3x +2.25) -18 -3(2.25) . . . . . complete the square
y = 3(x +1.5)^2 -24.75 . . . . . simplify to vertex form
