18 (goes down): 17, 16, 15
12 (goes up): 13, 14, 15
The shortest height at which the two stacks of boxes will be the same height is 15.
Hope I was able to help!
The formula is in a quadratic formula shape: ![y = ax^2+bx+c](https://tex.z-dn.net/?f=y%20%3D%20ax%5E2%2Bbx%2Bc)
The function is negative since the value 'a' the coefficient of x^2 is negative meaning that the quadratic function is facing downards. If you don't get this explanation, take a look at the diagram I uploaded.
That means the highest point of the graph is its vertex.
But we must find where the vertex is at or the 't' value.
't' value at which vertex is = ![-\frac{b}{2a} =-\frac{16}{2*(-16)} =\frac{1}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7Bb%7D%7B2a%7D%20%3D-%5Cfrac%7B16%7D%7B2%2A%28-16%29%7D%20%3D%5Cfrac%7B1%7D%7B2%7D)
Now plug this 't' value into h(t) to find the maximum height, and we will get 36 feet.
Hope that helps!
Answer:
a. 99.99 * .15 = 15 dollars off (14.9985 dollars)
b. 175000 *.07 = $12,250
c. rent = $2500 = x
y = total budget
y = 2500/.12 = $20,833.33
d. d = .19 * r
Step-by-step explanation:
Y÷1 =y
answer : y
because 1y means 1 times y
