M is directly proportional to r cubed when r = 4, m = 160. Find the value of r when m = 540
Anarel [89]

Answer:

r = 6

Step-by-step explanation:

Given that M is directly proportional to r³ then the equation relating them is

M = kr³ ← k is the constant of proportionality

To find k use the condition r = 4 when M = 160

k = \frac{M}{r^3} = \frac{160}{64} = 2.5, so

M = 2.5r³ ← equation of proportionality

When M = 540, then

540 = 2.5 r³ ( divide both sides by 2.5 )

216 = r³ ( take the cube root of both sides )

r = \sqrt[3]{216} = 6

What is the square root of 75 to the nearest integer
kodGreya [7K]

<u><em>5√3 is the correct answer.</em></u> First you had to find the prime factorization of 75, and it gave us, 3*5^2=5*5=25*3=75, or =\sqrt{5^2*3}. Then you can use apply radical rule, and it gave us, \sqrt{3} \sqrt{5^2}, or \sqrt{5^2}=5, and it gave us the answer is 5√3 is the correct answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie
