Answer:

see explanation

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 proportion

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

160 = k × 4³ = 64k ( divide both sides by 64 )

2.5 = k

M = 2.5r³ ← equation of variation

(a)

When r = 2, then

M = 2.5 × 2³ = 2.5 × 8 = 20

(b)

When M = 540, then

540 = 2.5r³ ( divide both sides by 2.5 )_

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

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

(6+3)-+8-7)=<br>(1+4)+(10-8)=<br>(3-3+(9+1)=<br>(10-2)+(10-8)=<br>2+(0+1+2+3)=<br>(10-1-2-3)+4=​
JulijaS [17]

Answer:

6+3-8-7 = 8

1+4+10-8 = 7

3-3+9+1 = 10

10-2+10-8 = 10

2+0+1+2+3 = 8

10-1-2-3+4 = 8

Semmy [17]
7v² - 47v + 30

7v² - 5v - 42v + 30       split the second term into two terms.

v(7v - 5) - 6(7v - 5)      factor out common terms in the first two terms, then the last two terms.

(7v - 5)(v - 6)      << is your answer

hope this helps, God bless!
