Answer:
(d) f(x) = 2x^2 - 16x + 35
Step-by-step explanation:
The x-coordinate of the extreme will be found at ...
x = -b/(2a)
where the function is f(x) = ax²+bx+c.
The extreme will be a minimum when a > 0. (eliminates choices A and B)
The x-coordinates of the extremes are ...
C: -(-4)/(2(4)) = 1/2
D: -(-16)/(2(2)) = 4 . . . . . matches the requirement
The appropriate choice is ...
f(x) = 2x^2 - 16x + 35
Answer:
x
Step-by-step explanation:
x^5
---------
x^4
When we divide exponents with the same base, we can subtract the exponents
x^(5-4)
x^1

Answer:
<em>m=1.7</em>
<em>C=68 gr</em>
Step-by-step explanation:
<u>Function Modeling</u>
We are given a relationship between the carbohydrates used by a professional tennis player during a strenuous workout and the time in minutes as 1.7 grams per minute. Being C the carbohydrates in grams and t the time in minutes, the model is

The slope m of the line is the coefficient of the independent variable, thus m=1.7
The graph of C vs t is shown in the image below.
To find how many carbohydrates the athlete would use in t=40 min, we plug in the value into the equation

15.80 * 1.05 should give you the answer
A method to solve it would be would be:
First converting 5% to a decimal then multiplying that by 15.80 in order the find 5 percent of 15.80...Afterwards you have to add that value to the original 15.80 ..And you should end up with the same answer.
