Below is the formula for the circumference of a circle
C = 2πr
This question gives us the diameter. To find the radius (r) you would divide the diameter by two like so...
16.4/ 2 = 8.2
Plug what you know into the formula and solve...
π = 3.14
r = 8.2
C = 2(3.14)(8.2)
C = 6.28(8.2)
C = 51.496
In the question it asks to round to the nearest tenth like so...
51.5

Step-by-step explanation:
explain to me what you are asking
- Given - <u>the </u><u>difference</u><u> </u><u>between </u><u>two </u><u>numbers </u><u>is </u><u>9</u><u> </u><u>and </u><u>the </u><u>numbers </u><u>are </u><u>in </u><u>the </u><u>ratio</u><u> </u><u>of </u><u>4</u><u>:</u><u>7</u>
- To find - <u>the </u><u>numbers</u>
Let the number be 4x and 7x respectively !
Then ,
therefore ,
<u>first </u><u>number</u> = 4x = 4 × 3 = <u>1</u><u>2</u>
<u>second</u><u> </u><u>number</u> = 7x = 7 × 3 = <u>2</u><u>1</u>

Answer:
I figured all these out by graphing the function. See the attachment for a picture.
h(x) = (x-1)^2
It's <u>increasing over (1, ∞)</u> because the values are going up in that span.
It's <u>decreasing over (-∞, 1)</u> because the values are going down in that span.
Its range is all values of <u>y </u><u> 0</u> (we can see that only y-values above 0 are in the function).
g(x) = -(x+1)(x-1)
It's <u>increasing over (-∞, 0)</u> because the values are going up in that span.
It's <u>decreasing over (0, ∞)</u> because the values are going down in that span.
Its range is all values of <u>y </u><u> -1</u> (we can see that only y-values below 1 are in the function).
