Wren's bedroom is 12 feet long x 10 feet wide. She plans to purchase carpet for the entire room. The carpet costs $25 per square meter. What are the dimensions in meters? Round each to nearest tenths place.
There are 3.28084 feet in a meter.
12*3.28084=39.30078
10*3.28084=32.8084
Length:39.3
Width:32.8
For a parabola equation ax^2+bx+c, the vertex would be -b/2a
Therefore, the x coordinate of the minimum would be -(-32)/2(2)=32/4=8
That is the "h" part of the equation.
Now, we need to find the y coordinate, which will be the "k" part of the equation. We can find that by plugging in x=8 into the equation: 2(8)^2-32(8)+56= -72
Therefore, we plug (h,k) and a in, and get the equation y=2(x-8)^2-72
The x coordinate of the minimum is 8
Answer:
5 months
Step-by-step explanation:
120 * 10m = 150 * 4m
subtract 4m to 10m
120 * 6m = 150
subtract 120 to 150
6m = 30
divide 6 to 30
30 / 6 = 5

The answer would be C
Because 20 x 20 is 400 and -20 x-20 is also 400
