Answer: 23
4x4=16 ( it represents the four weeks and the four inch growth each week)
Now just do 16+7 which equals to 23
Definition:
A function is "even" when f(x) = f(−x) for all x.
Geometrically speaking, the graph face of an even function is symmetric with respect to the y-axis, meaning that its graph remains unchanged after reflection about the y-axis.
If point (6, 8) is one the points on the graph of f(x), then f(6)=8 and since function is even, you can state that f(-6)=f(6)=8. This means that point (-6,8) must also be a point on the graph. Geometrically it means that the output of a negative x-value and its opposite is the same.
Answer: correct choice is A.
The answer for number 4 is 13 and number 6 is 121 and the last problem for number 7 is 112
"To solve this problem, the formula can be used
I = P / T
Where I is the fraction of the sample
P is the amount of the sample
T is the total amount of sample
Since P = 252 chicken sandwiches and I = 0.55
And solve for T
T = 252 / 0.52
T = 458 sandwiches in total"
hope this helps
