8 0

The trigonometric function are:
sin (opposite/hypotenuse)
cos (adjacent/hypotenuse)
tan (opposite/adjacent)

Their inverses are:
Inverse of sin: csc (hypotenuse/opposite)
Inverse of cos: sec (hypotenuse/adjacent)
Inverse of tan: cot (adjacent/opposite)

Hope this helps :)

Marlene rides her bicycle to her friend jon's house and returns home by the same route. marlene rides her bike at constant spee

To solve the problem:

Let f = distance one way distance on level ground

Let h = distance rode on the hill

Write a time equation; where Time = distance/speed:

level time + uphill time + downhill time + level time = 1hr

f/9 + h/6 + h/18 + f/9 = 1 hr

Multiply equation by 18 to get rid of the denominators

2f + 3h + h + 2f = 18

4f + 4h = 18

Simplify by dividing this by 4

f + h = 4.5 miles is took her to get to Jon’s house.

Which fraction has the same value as 0.6

Zinaida [17]

Using the place value chart we can see that the decimal 0.6 is six tenths, so we can write 0.6 as the fraction $\frac{6}{10}$ . Notice however that $\frac{6}{10}$ is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 6 and 10 which is 2.
