Answer:
7) (f+g) (x) = 4^x + 5x -5
8) (f-g) (x) = 4^x + x - 5
Step-by-step explanation:
7) Find (f +g)(x)
(4^x + 3x + 2x - 5)
(4^x + 5x -5)
(f+g) (x) = 4^x + 5x -5
8) Find (f-g)(x)
(4^x + 3x - 2x - 5)
(4^x + x - 5)
(f-g) (x) = 4^x + x - 5
Answer:
Choice D
y = 3(2/3)^x
Step-by-step explanation:
a) y = 2(3/2)^x = 3^x (pretty close)
b) y = (2/3)^x (wrong, coming from the wrong side)
c) y = 2(3)^x = 6^x (too close to y line)
d) y = 3(2/3)^x = 2^x (looks right)
The volume (V) is the product of base area (B) and height (h).
For Max's carton ...
V = Bh
V = (12 in²)*(6 in) = 72 in³
For Tucker's carton ...
V = Bh
V = (10 in²)*(7 in) = 70 in³
Max's carton has more volume than Tucker's carton by ...
72 in³ -70 in³ = 2 in³
We know this because we computed the volume of each carton and found the difference of those volumes.
