Answer:
Z=1.055
Step-by-step explanation:
Z is inversely proportional to X: 
Where K is a constant
X=18, Z=1.583333333333 we can find K value
K=Z*X =1.58333333333*12= 19
So, Using X=18 We have the following
= 1.055
Answer:
0.0425
Step-by-step explanation:
Answer:
The equation that can be used to solve for a is 1 = a(0=1)²-3.
Explanation:
In this case, I would model the parabola in vertex form. Vertex form is y = a(x-h)²+k, where (h,k) is the vertex of the parabola. Using the information from the question, we can plug in values to get 1 = a(0+1)²-3. (This could be simplified as 1 = a(1)²-3 ⇒ 1 = a-3 ⇒ a = 4, but we are only interested in finding the equation that can solve for a.)
There is some missing information here. There is nothing to select.
