The third one is different to the other three.
All the others can be written as x - 17
Meanwhile only the third one is written as x + 17.
Remeber the sequence of numbers can swap and + - makes -
- - makes +
Answer:
minimum at (2, - 2 )
Step-by-step explanation:
The equation of a parabola in vertex form is
f(x) = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
If a > 0 then the vertex is a minimum
If a < 0 then the vertex is a maximum
Given
f(x) = 2x² - 8x + 6 ← factor out 2 from the first 2 terms
= 2(x² - 4x) + 6
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² - 4x
f(x) = 2(x² + 2(- 2)x + 4 - 4) + 6
= 2(x - 2)² - 8 + 6
= 2(x - 2)² - 2 ← in vertex form
with vertex = (2, - 2) and a > 0
Thus minimum at (2, - 2 )
Answer:
13.6%
Step-by-step explanation:
Step 1
Find the actual volume of the box
Volume = Length × Width × Height
You measure the box and find that it has a length of 10 inches, a width of 9 inches, and a helght of 4.5 inches.
Volume = 10 inches × 9 inches × 4.5 inches
Volume of the box = 405 cubic inches
Step 2
Calculate the percent error
|Estimated value - Actual value|/Actual value ×100
Estimated value= 350 cubic inches
Actual value = 405 cubic inches
= |350 - 405|/405 × 100
= |-55|/405 × 100
= 55/405 × 100
= 13.580246914%
Approximately = 13.6%
The Percent error is 13.6%

Answer: (E) Not necessarily, because this wasn't an experiment
Step-by-step explanation:
As much as the results would suggest that the fast-paced music was responsible for the faster finishing time, this conclusion cannot be authoritatively made because this was not technically an experiment but rather a test to satisfy curiosity.
An experiment is planned and is scientific. It has more stringent requirements that ensure causation that Roshanda did not meet before she engaged in this trial so we cannot say for a fact that her findings are objective.
