Answer:
y = (5/4)2^x
Step-by-step explanation:
The function value increases by a factor of 40/10 = 4 when x increases by 2. The function can be written as ...
y = (reference value)·(growth factor)^((x -reference)/(change in x for growth factor))
y = 10·4^((x-3)/2) . . . . . . using point (3, 10) as a reference
This can be simplified to ...
y = 10·2^(x -3) = 10/8·2^x
y = (5/4)2^x
Answer:
The volume of the solid is either 346.5 in³ or 693 in³.
Step-by-step explanation:
The solid can either be a triangular prism or a rectangular cube.
- Consider the solid as a triangular prism.
The volume of a triangular prism is:
Here,
B = base
H = height
L = length
Let,
B = 7 in
H = 9 in
L = 11 in
Compute the volume of a triangular prism as follows:
Thus, the volume of a triangular prism is 346.5 in³.
- Consider the solid as a rectangular cube.
The volume of a rectangular cube is:
The values of L, B and H remains the same as above.
Compute the volume of a rectangular cube as follows:
Thus, the volume of a rectangular cube is 693 in³.
