Answer:
a) 96 = 3.57√h
b) h ≈ 723.11 m
Step-by-step explanation:
<h3>a)</h3>
The equation you want to solve is the model with the given values filled in.
D(h) = 3.57√h . . . . model
96 = 3.57√h . . . . . equation for seeing 96 km to the horizon
__
<h3>b)</h3>
We solve this equation by dividing by the coefficient of the root, then squaring both sides.
96/3.57 = √h
h ≈ 26.891² ≈ 723.11 . . . . meters above sea level
Dustin would need to have an elevation of 723.11 meters above sea level to see 96 km to the horizon.
Answer:
g(x) = |x-5|
Step-by-step explanation:
f(x) = |x|
y = f(x + C) C < 0 moves it right
g(x) = |x-5| moves it to the right 5 units
Answer:
h = 12
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
0.75h + 3 = 12
<u>Step 2: Solve for </u><em><u>h</u></em>
- Subtract 3 on both sides: 0.75h = 9
- Divide 0.75 on both sides: h = 12
<u>Step 3: Check</u>
<em>Plug in h into the original equation to verify it's a solution.</em>
- Substitute in <em>h</em>: 0.75(12) + 3 = 12
- Multiply: 9 + 3 = 12
- Add: 12 = 12
Here we see that 12 does indeed equal 12.
∴ h = 12 is a solution of the equation.
I believe the correct answer here would be B. The values x=2 and y=5 make the equation true. The answer is not A, because the graph could also go through 3 and 6. It is not C because that is not the correct order. The answer is not D because D is absurd and does not make sense.
