Step-by-step explanation:7% is 0.07.
0.07 * 3.1 trillion
3/4=12/16
12/16 is greater than 11/16
$1.79 i hope this helps you
<span>A)2x^2+3 is a transformation of f(x)=x^2: Stretch the graph vertically by a factor of 2 and then shift the entire resulting graph up by 3 units. The graph will still look like a parabola that opens up.
</span>B)-2x^2-3 is a transformation of f(x)=x^2: Stretch the graph vertically by a factor of 2, reflect the resulting graph in the x-axis, and then shift the entire resulting graph down by 3 units. The graph will still look like a parabola that opens down.

Answers to C and D are very similar, except that we compress the graph of x^2 v ertically by a factor of (1/2).
None of these A, B, C, D is wrong.

Answer:
There are 271.74 ft^2 not covered by the rug
The percentage not covered by the rug is 90.58%
Step-by-step explanation:
step 1
Find out the area of the room
The area of the rectangular room is

step 2
Find out the area of the circular rug
The area of the circle is

we have

----> the radius is half the diameter
substitute


step 3
Find out what percentage of the room is not covered by the rug
we know that
300 ft^2 represent the 100%
so
using proportion
Find out what percentage represent the difference (300-28.26)=271.74 ft^2
Let
x ----> the percentage not covered by the rug

Convert to fraction form

Simplify

therefore
There are 271.74 ft^2 not covered by the rug
The percentage not covered by the rug is 90.58%
