Answer:

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying the radicals in the expression

$\sqrt{52}$

= $\sqrt{4(13)}$

= $\sqrt{4}$ × $\sqrt{13}$

= 2 $\sqrt{13}$

------------------

$\sqrt{117}$

= $\sqrt{9(13)}$

= $\sqrt{9}$ × $\sqrt{13}$

= 3 $\sqrt{13}$

Then

$\sqrt{52}$ + $\sqrt{117}$

= 2 $\sqrt{13}$ + 3 $\sqrt{13}$

= 5 $\sqrt{13}$ → G

The parallelogram PQRS has vertices P (-2, 3), Q (1, 4), R (2, 6) and S (- 1, 5). Find the coordinates of the point of intersect

kondaur [170]

Call the intersection of 2 diagonal lines as I(a;b)
=> I is the midpoint of the diagonal PR
<=> a= (-2+2)/2. And. b=(3+6)/2
<=> a=0. And. b= 9/2
=> I(0;9/2)

Answer:

4/5

Step-by-step explanation:

Given :

A right angled triangle with sides 24 , 3 and 40 .

And we need to find the value of sinZ .

We know that , sine is the ratio of perpendicular and Hypotenuse. So that ,

$:\implies$ sinZ = p/h

$:\implies$ sin Z = 32/40

$:\implies$ sin Z = 4/5

Hence the renquired answer is 4/5.

State the equation of a line going through the points (4,1) and (-4,5).

Nikolay [14]

Answer:x+2y=6

Step-by-step explanation: Given points: (4,1) and (-4,5)

To find equation we need a slope and a point through which the line passes.

slope = (y1-y2)/(x1-x2)

= 1-5/4-(-4)

= -4/8

= -1/2

let the first point be the passing point,

eq. of a line: (y-y1)=slope(x-x1)

=(y-1)=-1/2(x-4)

=2y-2=-x+4

=x+2y=6
