Answer:
B. sine; 46.5 feet high
Step-by-step explanation:
In this case, we use trigonometric ratio.
Assuming the horizontal ground, the cable and the height of the cliff forms a triangle,
The cable is the hypotenuse, the height of the cliff is opposite to the angle formed by the cable and the horizontal ground.
Thus; the most appropriate function is sine
Such that;
Sine θ = Opposite/Hypotenuse
Where; θ = 25°, opposite is the height of the cliff and hypotenuse is the cable, 110 ft
Therefore;
Sine 25° = Opp/ 110
Hence;
Opp = 110 ft × sine 25°
= 46.488 ft
= 46.5 ft
Therefore;
The function is Sine, and the height of the cliff is 46.5 ft high
Given :
A stack of 500 pieces of paper is 1.654 inches tall.
Mulan guesses that each piece of paper is 0.045 inches thick.
To Find :
The actual thickness of paper and how is Mulan's answer is incorrect.
Solution :
Let, actual thickness is t.
So,
So, actual thickness is 0.003308 inches.
Therefore, the Mulan's answer is incorrect.
Answer:
Put those equations into desmos
Step-by-step explanation:
X=4
Step-by-step explanation:
Solve for x by moving all terms to the left side
7x+9=13+6x
subtract 6x from both side
7x+9-6x=13
subtract 6x from 7x
x+9=13
subtract 9 from both sides
x=4
The second one would be my best to choose out off all.
