Answer:
Step-by-step explanation:
use formula
F = 1/2*sqrt[ 4* r^2 -CD^2 ]
F = 4.4721
Answer:
x=1/14
Step-by-step explanation:
2/7x+2=6
left part times 7x = right part times 7x is:
2+14x=42x
2=28x
x=1/14
Answer:
2(7x + 2)
Step-by-step explanation:
Perimeter of a Rectangle = 2 x Length + 2 x Width.
Given Length = 4x, Width = 3x + 2,
Perimeter of Rectangle = 2(4x) + 2(3x + 2)
= 8x + 6x + 4
= 14x + 4 (Degree one polynomial)
= 2(7x + 2)
Answer:
y = 5/2 or 2.5
Step-by-step explanation:
If cos θ = (-5/13), then θ should be in quadrant II or III. The given says sin θ < 0, so θ should be in quadrant III. In this case, tan <span>θ should be equal to number greater than zero. Hence we get sqrt of (13^2 - 5^2 ) equal to 12. tan </span><span> θ should be equal to A 12/5. </span>
