80
Answer:
x > -1
Step-by-step explanation:
Domain is the set of x-values that can be inputted into function f(x).
From the graph we can see that our x-values span from -1 to infinity. Since -1 is open dot, it is not included in the domain:
(-1, ∞) or x > -1
Answer:
10.6 cm to the nearest tenth.
Step-by-step explanation:
If we let one side = x. So as each side of a square are equal, and using Pythagoras we have:
x^2 + x^2 = 15^2
2x^2 = 225
x^2 = 112.5
x = √112.5
x = 10.61.
Answer:
t ≤ 225r
Step-by-step explanation:
Distance = 225 miles
Time taken = t
Average speed = r miles per hour
Recall :
Speed = distance / time
Time, = distance / speed
t = 225 miles / r
All possible values of t :
t ≤ 225r
