Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result

x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7

x=4, y=28, 28=k(4), k=7

The constant of proportionality is 7; we check 2×7=14, 11×7=77

Answer: k=7, y=7x

Answer:

y=kx

y=k(7)x

y=7x(11)

y=7*11

y=77

Step-by-step explanation:

So with useing the equation that I used the porportional relationship is 7 so just fill 7 in for k. Then take the x number and fill it in for x. you will then multiply and get the y value.

Gravity pulls the metal down at 10 N, but the metal pieces RISES! At least how much force is needed to make it move upward?

prisoha [69]

Answer: Greater than 10 N

Step-by-step explanation:

Given

Gravity force on metal is 10 N

But the metal piece is rising i.e. there must be an upward force greater than 10 N

Suppose the force is F

So, we can write

$\Rightarrow F>10\ N$

Any force greater than 10 N is sufficient for the metal to move upwards

The greater the amount of force faster will be the movement

Dimas [21]

Answer:

572000

Step-by-step explanation:

The population reduced by 12%, so (100-12)=88% is remaining.

So, 88% of 650000= 0.88 x 650000

= 572000

What is the rationalizing factor of √3?

Vanyuwa [196]

Answer:

$± \sqrt{3} \: \: ( \sqrt{3} \: \: or \: \: - \sqrt{3} )$

Step-by-step explanation:

$\sqrt{3} \times \sqrt{3} = 3 \: \: (rationalize)$

$\sqrt{3} \times ( - \sqrt{3} ) = - 3$

The rationalizing factor of $\sqrt{ 3}$

is $\boxed{\green{\sqrt{3} \: \: or \: \: - \sqrt{3}}}$
