Check the picture below, so the parabola looks more or less like so, with a vertex at (0 , -7), let's recall the vertex is half-way between the focus point and the directrix.
so this horizontal parabola opens up to the left-hand-side, meaning that the "P" distance is a negative value.
Answer: The flagpole is 12.1 feet high.
Step-by-step explanation:
We can solve this by using a ratio:
Actual height to shadow length. The fractions must have the same equivalent values.
5.5/10 = x/22 Cross multiply the numerator on the left times the denominator on the right, and the denominator on the left by the numerator on the right:
5.5(22) = 10x
121 = 10x Divide both sides by 10. (10s "cancel" on the right)
12.1 = x
The flagpole is 12.1 feet high.
The solution is x> 4 or x ∈(4,∞)
Here equality given is
x - 1.2> 2.8
Rearrange the variable to the left side of the equation
x > 2.8 + 1.2
Calculate the sum
x > 4
Or we can also say
x ∈ (4,∞)
Therefore the range of x is x∈ (4,∞).
