Write an equation in point-slope form of the line having the given slope that contains the given point. then graph the line

Natali5045456 [20]

Answer:

$y=-\frac{5}{3}x-3$

Step-by-step explanation:

Equation of straight line in point slope form is given a s

$(y-y_1)=m(x=x_1)$

Here

$m=-\frac{5}{2} \ and\ (x_1, y_1)=(0, -3)$

$(y+3)=-\frac{5}{3}(x-0)$

$y=-\frac{5}{3}x-3$

Paper rectangle ABCD is folded in such a way that the fold passes through point B, and so A coincides with point H where H ∈ CD.

The answer is BC = 38.22 cm.

<u>Step-by-step explanation</u>:

We have, ∠BKD = 120° ,BK = 28 cm, Draw a perpendicular from point K on BC let it intersect at point M. In right angled ΔBMK, ∠BKM=30° and BK = 28 cm

sin30° = perpendicular/hypotenuse

1/2 = BM/BK

1/2 = BM/28

BM= 14 cm

Now , In right angled ΔBMK ,

cos30° = base/hypotenuse

√3/2 = MK/28

MK = 14√3 = 24.22 cm

KMCD is a square MK = MC = 24.22 cm

also, BC = BM + MC , putting values of BM & MC we get :

BC = 14 cm + 24.22 cm

BC = 38.22 cm.
