Answer:
2/n^4
Step-by-step explanation:
Anything to the zero power will become 1 so the m^0 will be 1 and that leaves just 2 in its place. Anything to a negative exponent is equal to its reciprocal so n^-1= 1/n^4. Then you multiple what remains, (2 x 1/n^4) to get the above answer.
Answer:
118°
Step-by-step explanation:
Line b is a perpendicular bisector so 90°+28°=118°
Triangle a - acute
Triangle b - acute
Triangle c - acute
Triangle d - right
Volume of the prism is the area of the triangle x the height.
To find the height find the area of the triAngle first, then divide the volume by the area.
Area = 1/2x 7x18 = 63 square mm
X = 1638/63
X = 26 mm
