4 0

You can use
$\frac{1}{2} ab \sin(c)$
Since it is an irregular triangle.
C refers to the angle and a & b refer to the adjacent sides.

So,
$\frac{1}{2} \times4.3 \times 3.8 \sin(53) \\ = 6.52485211 \\ = 6.52$

Find the distance between the points given. (2, 2) and (5, 5)

mario62 [17]

Distance between two points, d, is given by
$d= \sqrt{ ( x_{2} - x_{1}) ^{2} + (y_{2} - y_{1}) ^{2} }
$
where: (x1, y1) = (2, 2) and (x2, y2) = (5, 5)
$d= 
\sqrt{ ( 5 - 2) ^{2} + (5 - 2) ^{2} } \\ d= \sqrt{ (3)^{2} + 3^{2} } 
\\ d= \sqrt{9+9} \\ d= \sqrt{18} \\ d=3\sqrt{2} \ units$

Vertex form of y=x^2-4x-9

Scrat [10]

Complete the square
first isolate x terms
y=(x^2-4x)-9
complete square inside (take 1/2 of square of b )
-4/2=-2, (-2)^2=4
add 4-4 inside
y=(x^2-4x+4-4)-9
complete the square
y=((x-2)^2-4)-9
y=(x-2)^2-4-9
y=(x-2)^2-13
