Let the side of the square = a units,   the area of the square = a^2 sq units

Area of the 4 semicircles  = area of 2 circles = 2 pi r^2 =  2pi (1/2 a)^2
  =   pi a^2 / 2

Probability of a point in the unshaded square being picked)  = area square / area of the total figure  = a^2  / (a^2 * pi/2)   = 1 / pi/2 = 2 /pi

which is approximately  65%

Verify the identity: (1-sinx)/cosx = cosx/(1+sinx)
Tresset [83]
Cross multiply the expression so that we can get

(1+sinx)(1-sinx) = cos^2 x

1 - sin^2 x = cos^2 x

cos^2 x + sin^2 x = 1

since

cos^2 x + sin^2 x = 1 

therefore 

1 = 1

the two expressions are identical in a trigonometric sense

A car traveling at 88 km an hour over takes a bus traveling at 64 km an hour if the bus has a 1.5 hour Headstart how far from th
PIT_PIT [208]

Answer: 352 miles

Step-by-step explanation:

At the point where the car overtook the bus, the car and the bus would have travelled the same distance.

Let x represent the distance covered by bus and the car before the car overtook the bus.

Let t represent the time taken by the bus to travel x miles.

The bus was traveling at 64 km an hour.

Distance = speed × time

Distance travelled by the bus in t hours would be

x = 64 × t = 64t

if the bus has a 1.5 hour Headstart, it means that the car started moving 1.5 hours after the bus has moved.

Therefore, time spent by the car would be t - 15 hours.

The car traveling at 88 km an hour

Distance covered by the car in t - 1.5 hours would be

x = 88(t - 1.5) = 88t - 132

Since the distance covered is equal, then

88t - 132 = 64t

88t - 64t = 132

24t = 132

t = 132/24

t = 5.5 hours

Therefore, the distance from the starting point when the car overtook the bus would be

x = 64 × 5.5 = 352 miles
