Acertain city is experiencing a big crime wave. the city decides that it needs to put its police officers out into the streets to bring back security. the city is conveniently arranged into a 100 × 100 grid of streets. each street intersection can be identified by two integers (a, b) where 1 sas 100 and 1 s b s 100. the city 20x 20 subgrid (corresponding to grid points (a. b) with a s a 3a+ 19 and b sbsb+ 19 for valid (a) use the chernoff bound to compute the probability that a single subgrid gets at most 10 police (b) use the union bound together with the result from above to calculate the probability that the city a, b) gets more than 10 police officers. officers fails to meet its goal.

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

you meant circumference well the answer is:

17.27876 miles

area is 23.7583

the radius is 2.75 miles

hope this hmu if needed.
