First of all you times 2.16.... by 100 to get 21.61616.....
you then minus the original number to get 21.4.
You can then times that by 10 to why 214 and you can divide 214 by 99:
214/99 = 2.161616
Hope this helps! :)
If you put it in vertex form, it is easy to see the axis of symmetry.
f(x)-5=x^2-6x
f(x)-5+9=x^2-6x+9
f(x)+4=(x-3)^2
f(x)=(x-3)^2-4 so any value of x other than 3 increases the value of f(x), therefore the axis of symmetry is the vertical line x=3.
Answer:
D, Circle
Step-by-step explanation:
All the other shapes are 3D and have a volume.
Answer:
B. 71.43%
Step-by-step explanation:
The sensitivity is the probability that a test will indicate 'disease' among those with the disease, that is, the test has a positive results:
In this problem, we have that:
150 people with the disease tested positive and 60 tested negative. So the sensitivity is:
The correct answer is:
B. 71.43%
Since this table top is a square, we would expect it to have the same sides. So if your halfway, we can add another 150 1-inch square tile pieces, which makes it 300 inches (150 + 150 = 300; then multiplied by 1 inch).
(a) The dimension can be described using length and width values. So, its dimension is 300 x 300 inches.
(b) The diagonal from one corner to the opposite corner is calculated using the formula: d= √2a, where a represents the measurement of 1 side. Using the values and formula, the diagonal therefore measures 424.26 inches.
