The number 4 represents the number of pieces of candy she eats each day.
Answer:
Total number of trees planted = 
trees
Step-by-step explanation:
Trees planted by each student = 
Total number of students = 
Using unitary method to find total number of trees planted by all the students in school.
1 student plants = trees
student would plant = 
We apply the product rule of exponents to multiply ![[a^xa^y=a^{x+y}]](https://tex.z-dn.net/?f=%5Ba%5Exa%5Ey%3Da%5E%7Bx%2By%7D%5D)
⇒ 
⇒ 
⇒ trees
Total number of trees planted = trees

Answer:
y = -0.5(x - 4)^2 + 5.
y = -0.5x^2 + 4x - 3.
Step-by-step explanation:
The vertex is at (4, 5). so we have:
f(x) = a(x - 4)^2 + 5
When x = 0 y = -3 so substituting in the above:
- 3 = a(0-4)^2 + 5
-8 = 16a
a = -0.5.
So the vertex form is y = -0.5(x - 4)^2 + 5.
Standard form:
y = -0.5(x^2 - 8x + 16) + 5
y = -0.5x^2 + 4x - 8 + 5
y = -0.5x^2 + 4x - 3.
