I believe it is Row operations I took that class last year
Answer:
61%
Step-by-step explanation:
Reasoning: Theres 39% unshaded which means 61% is the shaded area
You are taking away 2 every time.
8
, 12 and 18 are less than 19 and have more factors than 19
, 21
, 23 and 25
.
Let's first take a look at our x here. --- (x + 2)^2
Because we are adding a two to our x, this means that we are shifting our graph 2 to the left. Remember that with functions, it's always the opposite!
There is nothing attached to the y, so we are not moving our function up or down.
And then the radius of our circle. Remember that the equation requires us to square this value (... = r^2), so we need to take the square root of 4. The square root of 4 is 2.
With this information, let's now look at our options.
Option A - INCORRECT, the radius is too large
Option B - INCORRECT, this was shifted 2 units to the right
Option C - INCORRECT, the radius is too large
Option D - CORRECT, the radius is 2 and the circle was shifted 2 units to the left
Hope this helps!! :)
