Answer:
31.25
Step-by-step explanation:
25/12=2.083333
15 x 2.0833333=31.24999999995
round up to get 31.25
Answer:
(2x-3)(2x+3)
Step-by-step explanation:
4x^2-0x-9
(4x^2-9)
(2x)^2 - (3)^2
We recognize that this is the difference of squares a^2 - b^2 = (a-b)(a+b)
(2x-3)(2x+3)
M to millimetres is 3 steps. m > dm > cm > mm. since it is 3 steps down, the comma goes 3 places left. 4 > 0,4 > 0,04 > 0,004. so 4 m is equal to 0,004 mm
Answer:
w is the length
Step-by-step explanation:
length squared is always the area of a square
Eccentricity of a given ellipse is dependent on how stretched (flattened) it is. A circle is a special case of ellipse but with no eccentricity. If you stretch a circle into an ellipse of greater eccentricity, the foci will get separated along with it. This implies that as the ellipse gets stretched more and more, the foci gets further apart so is the eccentric.
From the above info we can deduce that as the distance between foci decreases, the eccentricity will also reduce.
