Rational number just means that you can express it as a fraction, where both the numerator and denominator are integers & the denominator isn't 0.
Remember: whole numbers can be fractions. But, for example, the sqrt of 2 is irrational.
So:
-1.5
-1.75
-1.2
-1.9
-1.3
All of these are btwn -2 and -1. And they are all rational.

Step-by-step explanation:
W^7/W^-2=W^7+2=W^9 ( when divide subtract the exponent (7-(-2))
W^?/W² = W^?-2
W^9=W^(?-2)
9=?-2
?=11
W^7/W^-2 = W^11/W²

Answer:
AD/AB = AB/AC
Step-by-step explanation:
If we take two triangules in that figure: ABC and ABD, both are triangles rectangles. We need to use the definition of cosine, with the angle in th A corner, we called ∅.
For the ABC triangle: cos(∅) = adjacent cathetus/hypotenuse = AD/AB
For the ABD triangle: cos(∅) = adjacent cathetus/hypotenuse = AB/AC
Then:
cos(∅) = AD/AB = AB/AC
