Answer:
Answer C: g(x)
Step-by-step explanation:
I used a graphing calculator to graph f(x) = -x^2 + 4x - 5, and by doing so I immedately saw that the vertex of f(x) is at (2, -1).
The absolute max of g(x) is approximately (3.25, 6.1).
The absolute max of f(x) is approximately (2, -1).
Since the y-coordinate of the absolute maximum of g(x) is greater than the y-coordinate of the absolute maximum of f(x), we conclude that Answer C is correct: g(x) has the greater absolute maximum
Choice D
To factor a quadratic equation ax^2+bx+c, find two factors of a and write them in a column, one up, one down. Then find two factors of c and write them in a column. multiply the factors diagonally and add up the products to make b. if the products do not make b, switch the factors up down and try again till you have a match.
in this case,
-1 and 3 are the factors of -3, -5 and 1 are the factors of -15, -1 times 1 is 1, 3 times -5 is -15, -1 and -15 make a sum of -16. so you have (-1x-5)(3x+1)
take the negative sign out you have -(x+5)(3x+1)
I hope I've made myself clear.
First we get 30% ounces of peanuts in mixed nuts:
(0.3) * (32) = 9.6
To find the percentage of peanut concentration of the final mix if you add x ounces of peanuts:
% of peanuts = ((x + 9.6) / (x + 32)) * (100)
Answer:
An expression can be used is:
% of peanuts = ((x + 9.6) / (x + 32)) * (100)
Answer:
Option B is the answer.
Step-by-step explanation:
Which of the following best describes the memorization technique known as mnemonics?
B. linking information, such as a new vocabulary word, to a mental image that illustrates it in some fashion.
Memorization of the name allows for memorization of the associated idea. Like to remember rainbow colors, you can memorize Roy G. Biv to remember the colors of the rainbow.
