complete question:
A mini game cube is covered in different colors and has a side length of 1.8 inches. Which of the following would represent the amount of space covered in various colors?
A. 116.64 in2
B. 3.24 in2
C. 19.44 in2
D. 10.8 in2
Answer:
C. 19.44 in2
Step-by-step explanation:
A cube is a 3 dimensional figure bounded by 6 square faces. All the sides of a cube are equal in length. The picture below is a cube. The amount of space covered in different colors will be the surface area of the cube.
surface area = 6L²
where
L = length
L = 1.8 inches
surface area = 6 × 1.8²
surface area = 6 × 3.24
surface area = 19.44 inches²
Answer:
<u>Step-by-step explanation:</u>
To find the tangent, you need to find the derivative with respect to x.
Then substitute x = 1 into the derivative.
Given: 0 = 2x² - xy - y²
Derivative: 0 = 4x - y' - 2yy'
Solve for y': 2yy' + y' = 4x
y'(2y + 1) = 4x
