17.1 =17.1
Answer:
√10 / 10
Step-by-step explanation:
tan θ > 0 and sin θ < 0, so θ is in quadrant III. That means cos θ < 0.
cos(θ + π/4)
Use angle sum formula.
cos θ cos(π/4) − sin θ sin(π/4)
½√2 cos θ − ½√2 sin θ
Factor.
½√2 cos θ (1 − tan θ)
½√2 cos θ (1 − 2)
-½√2 cos θ
Write in terms of secant.
-½√2 / sec θ
Use Pythagorean identity (remember that cos θ < 0).
-½√2 / -√(1 + tan²θ)
-½√2 / -√(1 + 2²)
½√2 / √5
√10 / 10

(b) Isabel takes 7 minutes to run a mile
Answer:
Answer will be 
Step-by-step explanation:
We have given the expression 
We have to simplify this expression with the help of property of exponent
According to property of exponent when there is exponent to exponenet then both the exponent are multiplied with each other
So 
Here 4 and 3 are exponent to exponent so these are multiplied with each other
