Answer:

Sin (E) = √74/(2√23)

Step-by-step explanation:

Reference Angle = E

Hypotenuse = 2√23

Adjacent = 3√2

Opposite = DC = √(2√23)² - (3√2)²) = √(4*23 - 9*2) = √(92 - 18) = √74 (pythagorean theorem)

Recall SOHCAHTOA.

Thus,

Sin (E) = opp/hyp

Sin (E) = √74/(2√23)

Range of 100,212,215,303,308,600
Shalnov [3]

Answer:

The range is 500 :)

Step-by-step explanation:

the range is the difference between the largest number, in this case 600 and the smallest number, 100. So you do 600-100 which gives you 500.

A car traveling at constant speed traveled 262.5 miles in 3 1⁄2 hours. What was the car's speed?
makkiz [27]
Just divide 262.5 and 3 1/2.

262.5 / 3.5 = 75

So the car's speed was 75 miles per hour.
