Complete question :
Tim used the expression below, n³ where n represents side length, to determine the volume of a cube. Using this
expression, what is the volume of a cube with side length 3.5 inches? Show your work.
n?
Answer:
42.875 cubic inches
Step-by-step explanation:
Given that :
The formula to obtain the volume of a cube is n³ ; where n = side length of the cube.
The side length of a certain cube is given as = 3.5 inches.
The volume of the cube is calculated thus :
Volume = n³ = 3.5³
Volume = (3.5 * 3.5 * 3.5) inch³
Volume = 42.875 in³
This sine function has the form y = f(x) = a sin (bx + c), where |a| is the amplitude, b is the frequency, and c determines the phase shift.
The period of this sine curve is 2 pi/b, or (in this problem) 2 pi/(1/2).
The phase shift of this curve is -c/b, or -(pi/4)/(1/2). Simplify this.
The amplitude is |-3|, or just 3.
Draw a set of coordinate axes. Draw light horizontal lines through y=3 and y=-3. These are the max and min. values of this sine function.
Plot the phase shift on your x-axis.
Your sine function will begin at (phase shift value, 0) and continue for one period. Add the period to the phase shift value. Draw a sine curve beginning and ending at these two x-values.
I encourage you to share your calculations and to sketch the graph described here. Then I could give you more specific feedback on your work. Good luck!
Answer:
Step-by-step explanation:
1) divide equilateral tri from the middle you will get two 30-60-90 triangles
2) by using pythagorean law & trigimintory, you will get two unknowns (height and side length) and two functions
