Answer:

You can't solve this with only this much info.

Step-by-step explanation:

There are 2 varibles y and x. You have to at least have 2 different equations with only variables y and x or know the value of one. Of course you could guess but then there would be multiple answers. like y=1, x=2.5, etc.

A line that is not parallel nor perpendicular to y=2/4x+1

DENIUS [597]

Answer:

y=2x+1

Step-by-step explanation:

Parallel = gradients are the same

Example: y=2/4x+5

Perpendicular = gradients are the inverse of each other

Example: y= -4/2x+1

Any equation would be correct unless the gradient is 2/4 or -4/2

A circle inside of a square. The circle touches all sides of the square. The base is 5 centimeters.

lina2011 [118]

Answer:

19.6 cm²

Step-by-step explanation:

If a circle fits perfectly inside of a square, then its diameter is equal to the length of sides of the square.

The area of a circle is given by:

$A= \pi \frac{d^2}{4}$

In this problem, d = 5 cm, the area of the circle is:

$A= 3.14 *\frac{5^2}{4} \\A=19.6\ cm^2$

The approximate area of the circle is 19.6 cm².
