Answer: -1

Step-by-step explanation:

xz/-2y, given x=-3, y=6, and z=-4

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

xz/-2y

=(-3)(-4)/-2(6) ⇔ substitute x y and z value

=12/-12 ⇔ calculate it

=-1 ⇔ simplify fraction

Hope this helps!! :)

What is the General form of the parabola of (y-3)^2=6(x+8)

MatroZZZ [7]

Answer:

x = 1.5 $t^{2}$ , y = 3 + 2at.

Step-by-step explanation:

For the parabola $Y^{2}$ = 4aX ,

General form will be

(X = a $t^{2}$ , Y = 2at) ,

Thus , for the parabola $(y-3)^{2}$ = 6(x +8)

Here , a = 1.5 and Y from the above equation should be substituted by y - 3 and X must be substituted by x + 8. After substitution of the same we can use the general equation formula for this parabola also.

Thus , general equation comes out to be :-

x + 8 = 1.5 $t^{2}$ , y - 3 = 2at

x = 1.5 $t^{2}$ , y = 3 + 2at.

Question 3

Elza [17]

Answer:

Perimeter is 126cm and area is 972 $cm^2$

Step-by-step explanation:

Scale factor means you multiply the dimensions by the factor. In this case 4.5

The width 6cm becomes 27cm. The length 8cm becomes 36cm.

Perimeter = 2*L + 2*W, L is length and W is width.

$P=27*2cm+36*2cm\\P=54cm+72cm\\P=126cm$

Area = L*W

$A=27cm*36cm\\A=972cm^2$
