Answer:The three dimensional diagonal of a rectangular prism is:
d^2=x^2+y^2+z^2, and since this is a cube, x=y=z=s, and we are told that s=3
d^2=3s^2 and s=3
d^2=3(3^2)
d^2=3(9)
d^2=27
d=√27
Answer:
105, because 50% means it is half or in the middle of the box graph
Answer:
The angle subtended by the arc is 171.8873385 degrees (3 radians)
Step-by-step explanation:
The formula of the length of an arc of a sector is L = × 2 π r, where
- x is the central angle subtended by the arc
- r is the radius of the circle
∵ An arc of a sector is three times its radius
∴ L = 3r
→ Equate the formula of the length of the arc by 3r
∵ × 2 π r = 3r
→ Divide both sides by r
∴ × 2 π = 3
→ Simplify the left side
∵ x = 3
→ Divide both sides by
∴ x = 171.8873385°
∴ The angle subtended by the arc is 171.8873385 degrees (3 radians)
Answer:
A. 3x+14≥ 2 or 1-x ≥-5
Step-by-step explanation:
the solutions should be x≥ -4 or x ≤6
and the right answer is :
3x + 14≥ 2
3x ≥ -12
x≥ -4
1-x ≥ -5
-x ≥ -6
x ≤ 6
A. 3x+14≥ 2 or 1-x ≥-5
