The anser is 11 you can see
We are looking for functions where f(-x) = f(x)
Let's test every function.
f(-x) = (-x)^4 - (-x)^2 = x^4 - x^2 = f(x)
The first function is even
f(-x) = (-x)^2 - 3(-x) + 2 = x^2 + 3x + 2 ≠ f(x)
The second function is not even.
f(-x) = √(-x-2) ≠ f(x)
The third function is not even
f(-x) = |-x| = |x| = f(x)
The last function is even.
Thus, the first and last choices contain even functions.
Have an awesome day! :)
Answer:
Option c.
Step-by-step explanation:
Exponential growth and decay functions are written in standard form as
.......... (1)
where is an initial amount, b is the growth factor and k is the growth rate.
We have to say what t denotes in the equation (1) and choose from the given options.
I think t denotes the time in this equation, hence, option c will be correct. (Answer)
Time spent on Internet + video games = 10 + 13 = 23 hours.
Total free time in a week = 5 * 7 = 35 hours
Percentage = 23/35 * 100 = 65.71%
In short, Your Answer would be 65.71%
Hope this helps!
Hey there! I'm happy to help!
The words at most means that there is a maximum point that is included as a probability. This means that we will use the less than or equal sign (≤) in our inequality.
Let's write this all out as an inequality now. We will use i to represent how much the baby ate.
1,800≤2i+250
This inequality shows that Alexandria's 1,800 calories is at most 250 more than twice those of her baby sister. Therefore, the correct option is A. 1,800≤250+2i .
Have a wonderful day!
