Answer:
(1,-4)
Step-by-step explanation:
x = -b/2a
a = 2
b = -4
x = 4/4
x = 1
Then substitute x = 1 into the equation to find y
y = 2(1)^2 - 4(1) - 2
y = -4
So, (1,-4)
A.

Answer:
See below
Step-by-step explanation:
(7 x 10³) × 2
7 x 10³ × 2
14 × 10³
14 × 1,000
14 × 1,000 = 14,000 or 1.4 × 10^4
<em>Final Answer: 14,000 / 1.4 x 10^4</em>

Answer:
The height of the parallelogram is 20m
Step-by-step explanation:
Given the area of a parallelogram
A = bh where;
b is the base and h is the height
If the base and height of a parallelogram are in the ratio of 6:5. It's area is 480 inches, this means that b/h = 6/5
5b = 6h
b = 6h/5
Substituting equation 1 into the volume if the parallelogram we have;
A = 6h/5×h
480 = 6h²/5
6h² = 480×5
6h² = 2400
h² = 2400/6
h² = 400
h = √400
h = 20m
