Square root to the nearest tenth √1.001 ,√1.1212 ,√2.895, √4.005 ,√6.2533

Svetlanka [38]

Answer:

1.0 ; 1.1 ; 1.7 ; 2.0 ; 2.5

Step-by-step explanation:

Given the following :

√1.001 ,√1.1212 ,√2.895, √4.005 ,√6.2533

The square root to the nearest tenth :

Using calculator :

√1.001 = 1.0004998 = 1.0

√1.1212 = 1.0588673 = 1.1

√2.895 = 1.7014699 = 1.7

√4.005 = 2.0012496 = 2.0

√6.2533 = 2.5006599 = 2.5

Solving simultaneous equations with one quadratic, x^2+y^2=16 and y=x+3

Svetlanka [38]

If $y=x+3$ , then in the first equation you have

$x^2+(x+3)^2=x^2+(x^2+6x+9)=2x^2+6x+9=16$

Rewriting a bit, you get

$x^2+3x+\dfrac92=8$

$x^2+3x+\dfrac94+\dfrac94=8$

$\left(x+\dfrac32\right)^2=\dfrac{23}4$

$x=-\dfrac32\pm\dfrac{\sqrt{23}}2$

Now, since $y=x+3$ , you also get

$y=-\dfrac32\pm\dfrac{\sqrt{23}}2+3=\dfrac32\pm\dfrac{\sqrt{23}}2$

So, there are two solutions here:

$(x,y)=\left(-\dfrac32+\dfrac{\sqrt{23}}2,\dfrac32+\dfrac{\sqrt{23}}2\right)$
$(x,y)=\left(-\dfrac32-\dfrac{\sqrt{23}}2,\dfrac32-\dfrac{\sqrt{23}}2\right)$
