Answer:
sine 52 degrees = height / 78
height = 78 * sine 52
height = 78 * 0.78801
height = 61.46478 feet
rounded to nearest tenth 61.5 feet
Step-by-step explanation:
-13+3b = -5-b
4b -13 = -5
4b = 8
b= 2
It is unknown since there is a 50-50 chance it could be heads or tails
Answer:
both plumbers charge $120 for 3 hours of work
Step-by-step explanation:
1) x=3 and x stands for hours.
2) 120=y and y stands for money charged
so the points (3, 120) show that the plumbers both charge 120 for 3 hrs.
So, f(x) is a composite function. This means that g(x) is inside of h(x); in other words, you would substitute g(x) for x in h(x).
Something happened to g(x) (in the form of h(x)) to turn it into f(x). You should notice that f(x) is simply g(x) raised to the third power.
Therefore, h(x) = x^3
You can check this by working it backwards.
Start with: h(x) = x^3
Substitute: x = g(x) = 4x^2-11
Now you have: h(x) = (g(x))^3 = (4x^2-11)^3
Hope this helps!
