Answer :
Answer: Radius of a solid aluminium sphere is 3.67 cm.
Step-by-step explanation:
4/3 · 2.57³ π · 7,860 = 4/3 · r³ π · 2,700 / : 4/3 π
2.57³ · 7860 = r³ · 2,700
r³ = 2.57³ · ( 7,860 : 2.700 ) = 2.57³ · 2.911111... /∛
r ≈ 2.57 · 1.428 = 3.67 cm
For two lines to be parallel, they must have the same slope...
3y=-5x+15
y=-5x/3 +5, y=mx+b, where m=slope so:
A parallel line with have a slope of -5/3
Answer:
3x³ + 12x
Step-by-step explanation:
Given
3x(x² + 4) ← multiply each term in the parenthesis by 3x
= 3x³ + 12x
Answer:
(x+4)^2 + (y+3)^2 = 5^2
Step-by-step explanation:
The equation of a circle is
(x-h)^2 + (y-k)^2 = r^2
now substitute the known values
(x+4)^2 + (y+3)^2 = 5^2
and theres your equation
