Draw a right triangle ABC with, the point where the top touches the ground and one leg, BC, the stump, measuring 14 ft.
The height of the tree = hypotenuse + stump BC (14 ft)
If the ∠ of inclination = 43°, then ∠ CAB = 37°
Now let's apply the law of sine:
sin 37°/14 = sin 43°/AB →and AB = 14.sin 43°/sin 37° = 15.86
Hypotenise² = AB² + CB²
Hypotenuse² = 15.85² + 14² = 447.22 → and Hypotenuse = 21.14 ft
Tree Height = hypotenuse + stump = 21.14 + 14 ≈ 35 ft
There's a 1 in 7 chance it will land on G.
Answer:
64
Step-by-step explanation:
180-52/2=128/2=64
Number 5 is 15.9 kilograms
And number 6 is 6 million cubic feet per minute
You just cross multiply
Answer:
(f - g)(x) = x^4 - x^3 - 4x^2 - 3
Step-by-step explanation:
Subtract g(x)=x^3 + 3x^2 + 12 from f(x)= x^4 - x^2 + 9
First, take the negative of every term (including the label g(x) ) of g(x), obtaining -g(x) = -x^3 - 3x^2 - 12.
Now combine this result with f(x):
f(x)= x^4 - 0x^3 - x^2 + 9
-g(x) = - 1x^3 - 3x^2 - 12
---------------------------------------
(f - g)(x) = x^4 - x^3 - 4x^2 - 3
