3.2 x 10^5
Step-by-step explanation:
Scientific Notation
3.2 x 10^4 = 32000
3.2 x 10^5 = 320000
Given:
area of square, A = 16 ![cm^{2}](https://tex.z-dn.net/?f=cm%5E%7B2%7D)
error in area, dA = 0.03 cm^{2}
Step-by-Step Explanation:
Let 'a' be the side of the square
area of square, A =
(1)
A = 16 = ![a^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D)
Therefore, a = 4 cm
for max tolerable error in length 'da', differentiate eqn (1) w.r.t 'a':
dA = 2a da
![0.03 = 2\times 4\times da](https://tex.z-dn.net/?f=0.03%20%3D%202%5Ctimes%204%5Ctimes%20da)
da = ![\frac{0.03}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B0.03%7D%7B8%7D)
da = 0.0375 cm
Answer:
The answer would be 1/6
Step-by-step explanation:
That is because 1/3 divided by 2 equals 6. Hope this helps.
Answer:
Point N will be located between 0 and -1.
Step-by-step explanation:
Points A and D are placed at (-4, 0) and (4, 0) on a number line.
We have to find the location of a point N which divides AD in the ratio of 3 : 4.
Coordinates of a point (x, y) which divides a segment with extreme ends at
and
in the ratio of m : n is given by,
x = ![\frac{mx_2+nx_1}{m+n}](https://tex.z-dn.net/?f=%5Cfrac%7Bmx_2%2Bnx_1%7D%7Bm%2Bn%7D)
y = ![\frac{my_2+ny_1}{m+n}](https://tex.z-dn.net/?f=%5Cfrac%7Bmy_2%2Bny_1%7D%7Bm%2Bn%7D)
By this formula, coordinates of the point N will be,
x = ![\frac{3(4)+4(-4)}{3+4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%284%29%2B4%28-4%29%7D%7B3%2B4%7D)
x = ![-\frac{4}{7}](https://tex.z-dn.net/?f=-%5Cfrac%7B4%7D%7B7%7D)
y = 0
Therefore, coordinates of the point N are
.
Point N will be located between 0 and -1.
