Find xy if x + y=3, x^2 + y^2 = 5

Answer:

mark me

Step-by-step explanation:

x+y=3

x=3-y

putting the value of x

in this

x²+y²=5

(3-y) ²+y²=5

9-6y+y²+y²=5

2y²-6y+9-5=0

2y²-6y+4=0

2y²-4y-2y+4=0

2y(y-2)-2(y-2)=0

(2y-2) (y-2) =0

2y-2=0 or y-2=0

y=1 or y=2

so x=2 or 1

so x×y=2×1 or 1×2=2

I HOPE THIS WILL HELP YOU MARK ME BRAINLIEST

In a circle with center P and radius 10cm. If one of the chord is of length 12 cm.

juin [17]

Look at the attachment

The line bisects the cord which we have to find

Length of chord=12cm
Half of the cord=12/2=6cm
Radius=10cm

Its a right angle triangle

using Pythagorean theorem

$\boxed{\sf P^2=H^2-B^2}$

$\\ \Large\sf\longmapsto P=\sqrt{H^2-B^2}$

$\\ \Large\sf\longmapsto P=\sqrt{10^2-6^2}$

$\\ \Large\sf\longmapsto P=\sqrt{100-36}$

$\\ \Large\sf\longmapsto P=\sqrt{64}$

$\\ \Large\sf\longmapsto P=8cm$

Distance of the chord from centre is 8cm.
