Ruth sets out to visit her friend ward, who lives 20 mi north and 100 mi east of her. she starts by driving east, but after 70 mi she comes to a detour that takes her 15 mi south before going east again. she then drives east for 8 mi and runs out of gas, so ward flies there in his small plane to get her.

Solution:

Distance between Ruth House and Ruth Friend House =20 Meter north and 100 meter east of Ruth

Now , Ruth Starts Driving,

but after 70 mi she comes to a detour that takes her 15 mi south before going east again. she then drives east for 8 mi and runs out of gas.

The Diagram of Ruth Driving is depicted below.

Now , when ward flies in small plane to get Ruth,

So, Distance between Ruth and Ward , when Ruth is at Point S=SM

In Right Δ SVM, By Using Pythagoras theorem

SM²=SV² + VM²

DT=VS=15 m

VM=100 - (70+8)

     = 100 -78

     =22 meter

SM²=(15)² + (22)²

       = 225 + 484

       = 709

So, Ward has to travel 26.62 miles east north to reach Ruth.

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
