first lets normalize the equation into y=... form. We can do this by dividing all by 4:
y=(5/4)x - 2
5/4 is the gradient of this line. The perpendicular line will have the negative reciprocal gradient, ie., -4/5, so we're looking for a value of -4/5 in front of the x.
That's only answer B. But it has to go through (-5,4). If you fill in -5, you get -5*-4/5 = +4. So y=(-4/5)x is indeed the correct answer.
The volume of the cylinder with a height of 9 cm and a radius of 5 cm is 706.9 cm³, if the radius is doubled, the volume would be 2827.4 cm³ (4 times)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Volume of cylinder = π * radius² * height = π * 5² * 9 = 706.9 cm³
If the radius is doubled:
Volume of cylinder = π * (2 * 5)² * 9 = 2827.4 cm³
The volume of the cylinder with a height of 9 cm and a radius of 5 cm is 706.9 cm³, if the radius is doubled, the volume would be 2827.4 cm³ (4 times)
