Answer:
cos(X+Y) = cos(55+35) = cos(90) = 0
Step-by-step explanation:
cos(X+Y) = cosXcosY - sinXsinY
cos(55+35) = cos(55)cos(35) - sin(55)sin(35)
cos(55+35) = cos(55)cos(35) - cos(90-55)cos(90-35)
cos(55+35) = cos(55)cos(35) - cos(35)cos(55)
cos(55+35) = 0
cos(90) = 0
The Surface area of the cube will be 433.5 square feet. Then the correct option is C.
<h3>What is a surface area of a cube?</h3>
Suppose that: The side length of the considered cube is L units. Then, we get:
Surface area of that cube = 6L² square units.
Bella is wrapping a cube shape box that measures 8.5 inches along each side.
The edge length of the cube is 8.5 meters.
Then the Surface area of the cube will be
Surface area = 6 x 8.5²
Surface area = 6 x 72.25
Surface area = 433.5 square feet
The Surface area of the cube will be 433.5 square feet.
Then the correct option is C.

Answer:
The slope intercept form involves solving for y, such that the equation looks like this: y = mx + b, where m is a constant representing the slope of the line, and b is a constant representing the value of the y-intercept.
Starting with the equation x+2y=6 and subtracting x from both sides gives 2y = -x + 6.
If we then divide each term by 2, we get the final result of y = -1/2x + 3.
Here we see that the slope (m) is equal to -1/2, and the y-intercept (b) is 3.
