The length of a spring varies directly with the mass of an object that is attached to it. When a 30-gram object is attached, the

Artyom0805 [142]

Answer:

$s = \frac{3}{10}m$

Step-by-step explanation:

Given

Mass = 30g

Spring Stretch = 9cm

Variation: Direct Variation

Required

Equation that relates the mass of the object, m, and the length of the spring, s

Let m represents mass and s represents length of the spring

Given that s varies directly to m;

This implies that

$s\ \alpha\ m$

Convert the above to an equation

$s = km$ ; where k is the constant of variation;

The next step is to solve for k

Divide both sides by m

$\frac{s}{m} = \frac{km}{m}$

$\frac{s}{m} = k$

$k = \frac{s}{m}$

From the given parameters;

when m = 30; s = 9.

$k = \frac{9}{30}$

Divide the numerator and denominator by 3

$k = \frac{3}{10}$

To get the equation that relates the mass of the object to the length of the spring

Substitute $k = \frac{3}{10}$ in $s = km$

This becomes

$s = \frac{3}{10}m$

Hence, the equation that relates the mass and length is $s = \frac{3}{10}m$

Which expression is equivalent to the given polynomial expression?

Greeley [361]

Answer:

The equivalent expression is: $-5a^2 + 4ab + 116$

Step-by-step explanation:

An equivalent expression to the one given can be found removing first from the parenthesis, and then combining the like terms. So

$(-4a^2 - 36) + (-2ab - a^2 + 2) + (-82 + 6ab)$

Removing from the parenthesis

$-4a^2 - 36 - 2ab - a^2 + 2 - 82 + 6ab$

Combining the like terms:

$-4a^2 - a^2 - 2ab + 6ab - 36 + 2 - 82$

$-5a^2 + 4ab + 116$

The equivalent expression is: $-5a^2 + 4ab + 116$
