Answer:
-3 < x ≤ 7
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
We can see from the graph that our x-values that can be inputted are from -3 to 7. Since -3 is an open dot, we cannot include this in our domain.
∴ -3 < x ≤ 7
Answer:
not sure,but I think the answer is 3 to 4
You would divide them both my two to get 9/7
Answer:
Volume is 3.05m³
Step-by-step explanation:
This problem bothers on the mensuration of solid shapes, sphere
Step one
The formula for the volume of a sphere is expressed as
V=4/3πr³
Step two
Given data
Diameter d = 1.8m
Radius r = d/2= 1.8/2= 0.9m
Step three
Substituting our given data we have
V= 4/3*3.142*0.9³
V= 4/3*3.142*0.729
V= 9.162/3
V=3.05m³
8/14 boys, 6/14 girls which means 4/7 boys and 3/7 girls
