Answer:
7/4 +1/6 +X=15/2
1/6+X=15/2-7/4
1/6+X=30/4-7/4
X=23/4 - 1/6
X= 138-4/24
134/24

Answer:
(f ○ g)(- 6) = 1
Step-by-step explanation:
Find g(- 6) from graph then use this value to find f, that is
When x = - 6 then g(- 6) = 4 ← from graph
When x = 4 then f(4) = 1 ← from graph
Thus (f ○ g)(- 6) = 1
It is.c because of its 3x^2 square units
Answer:
W is concave up.
Step-by-step explanation:
We are filling a spherical tank starting at the top half (meaning it is fulled half initially) at a constant rate. So, the tank level will increase in proportion to the tank's diameter at a given height.
Since the area of the circle is π·r² , then W(t) will be an increasing curve of second degree.
So, the curve for W(t) is concave up.
Also, the tank level increases over time at a more rapid rate.
Hence, the graph of W is concave up.
