Answer: Vertex (5 ,-9)
Step-by-step explanation:
Given : Function f(x) = (x – 8)(x – 2).
To find : What is the vertex of the quadratic function .
Solution : We have given that f(x) = (x – 8)(x – 2).
On removing parenthesis
f(x) = x²-2x -8x +16.
f(x) = x²-10x +16.
We need to find vertex of this function ,
Vertex: (h, k)
h = -.
Plugging values
h = -.
h = 5 this is the x- coordinate,
Now , we will plug x= 5 in quadratic function .
k = (5)²-10(5)+16.
k = 25-50 + 16
k= -9.
Vertex (5 ,-9)
Therefore, Vertex (5 ,-9).
10 * 2 TENS IS BASICALLY... 10 * 20. 10 * 20 IS 200.
Answer: option B
Step-by-step explanation:
Suppose you take a measure for each 5 seconds in a given observation, and the thing you are observing seems to change in the same amount in each meassure. This may mean that you are observing a linear relationship of the form y = a*x + b
Then, the simpler way to study this data set is by fiting with a linear equation.
The next bigger tenth is 0.5 .
The next smaller tenth is 0.4 .
0.473 is closer to 0.5 than it is to 0.4 . So the nearest tenth is 0.5 .
