The area of the rectangle is length times width, that is
A = L*W
The problem requires the width so
W = A/L
Given that A = 437 sq. cm and L = 19 cm, therefore
W = 437/19 = 23 cm

That is the answer.

Find the point-slope equation for

iris [78.8K]

Answer: y+9=-2(x-9)

Step-by-step explanation:

The point-slope equation is $y-y_{1} =m(x-x_{1} )$ . All we have to do is fill in all the values except for y and x.

To find m, you use $\frac{y_{2}-y_{1} }{x_{2} -x_{1} }$ . Since we are given 2 points, we cna plug them in.

$\frac{13-(-9)}{-2-9} =\frac{22}{-11} =-2$ . Now that we have our slope m, we can fill in the point slope equation.

$y-(-9)=-2(x-9)$

$y+9=-2(x-9)$

The density of copper is 9.86 g/cm3.

eimsori [14]

Answer:

1.479 kg

Step-by-step explanation:

density = mass / volume

9.86 g/cm3 = mass / (3 x 10 x 5)

9.86 = mass / 150

9.86 x 150 = 1479 g

1479 / 1000 = 1.479kg
