Answer:
21.3541565041
Step-by-step explanation:
You can look it up online to easily find it. Thats how i found this answer.
Hope this helps!
<span>First of all, there should be coherence for the units of measurement -- either they are all meters or they are all ft. I would assume they are all ft.
The correct answer is 75 ft above. T
The explanation is the following: suppose the ground level is the x-axis, the 2 feet of the arch lie respectively on (0,0) and (100,0) on the ground level. Since the arch is 100ft high, the vertex of the parabola will be the point (100,100). Thus, we can find the equation describing the parabola by putting the three points we know in a system and we find that the equation of the parabola is y=(-1/100)x^2+2
To find the focus F, we apply the formula for the focus of a vertical axis parabola, i.e. F(-b/2a;(1-b^2+4ac)/4a).
By substituting a=-1/100, b=2 and c=0 into the formula, we find that the coordinates of the focus F are (100,75).
So we conclude that the focus lies 75ft above ground.</span>
Answer:
B
Step-by-step explanation:
Also the answer must be under 9 so that rules out option D
Because We know CE = 2 and AD is visibly larger than CE, 6We can rule out option A
And that brings us down to B and C
CB is equal to 6, And I'm no genius, but I'm pretty sure AD is DEFINATLY not equal to 6.
so the answer is B
Answer:
From largest to smallest: FG, FH, GH
Step-by-step explanation:
Given
Required
Order the sides in descending order
First, we need to solve for x.
Perimeter of FGH is calculated as thus:
Substitute values for FG, GH, FH and Perimeter
Collect Like Terms
Reorder
Divide through by 24
Substitute 4 for x in FG, GH and FH
In order of arrangement in descending order, we have:
