Answer:
3y^20/x^4
Step-by-step explanation:
Area of a square = pie r^2.
Radius = sqrt 484 = 22.
Diameter = 2 r = 2 x 22 = 44.
Hope this helps!
The minimum is 91. The first quartile is 112. The median is 173. The third quartile is 215. The maximum is 253.
The smallest region that can be photographed is
5*7 = 35 square km
so we want to know how long it takes to zoom out to an area of
35 * 5 = 175 square km.
Notice that the length and width increase at the same rate, 2 km/sec, and they start out with a difference of two, so when the width has increased from 5 to x, the length will have increased from 7 to x+2. At the desired coverage area, then,
x(x+2) = 175
x^2 + 2x = 175
x^2 + 2x + 1 = 176 [completing the square]
(x+1)^2 = 176
x+1 = ±4√11
x = -1 ±4√11
Since a negative value for x is meaningless here, x must be
-1 + 4√11 = about 12.27 km
and the time it took to increast to that value was
(12.27 - 5) km / (2 km/sec) = about 3.63 seconds
If the length is the same as one leg, than all the other legs should be the same exact dimensions, legs can not be different measurements by height.
Hope that this help you!
