Find the vertex for y=3x^2-6x+5

Mkey [24]

The x value of the vertex in
ax^2+bx+c is -b/2a

y value is just sub for x

3x^2-6x+5
x value of vertex is -(-6)/(2*3)=6/6=1

sub back
y=3(1)^2-6(1)+5
y=3(1)-6+5
y=3-1
y=2

vertex is (1,2)

9. A rectangle has an area of 45m²

love history [14]

Answer:

$Lenght=3\,m$

Product of length and width= $45$

Step-by-step explanation:

The product of the length and width of the rectangle is called the area of the rectangle.

Area of the rectangle= $45\,m^2$

$Width=15\,m$

Area of the rectangle= $Length\times Width$

$45=Length\times 15\\\\Length=\dfrac{45}{15}\\\\ Length=3\,m$

The product of the Length and Width of the rectangle is :

$=3\times15\\\\=45 m^2$ i.e area of the rectangle.
