Hey there! I'm happy to help!
We have a room that is 22 by 17 feet. We know that for every foot, we draw a 1/2 inch. This means that we need multiply our dimensions by 1/2 to find the dimensions of the drawing.
22×1/2=11
17×1/2=8.5
Therefore, the dimensions of the room are 11 feet by 8.5 inches. These are the dimensions of a normal white paper!
Have a wonderful day! :D
$18.72
20% of $15.60 is $3.12
$15.60+$3.12=$18.72
For given problem:
Put midpoint of ellipse, (0,0) at epicenter of bridge at
ground level.
Specified length of vertical major axis = 70=2a
a=35
a^2=1225
Equation of ellipse:
x^2/b^2+y^2=1
plug in coordinates of given point on ellipse(25, 10)
25^2/b^2 + 10^2/a^2 = 1
625/b^2 + 100/1225=1
625/b^2 = 1 - 100/ 1225 = .918
b^2 = 625/.918 ≈ 681
b ≈ 26.09
length of minor axis = 2b = 2(26.09) ≈ 52.16 ft
Span of bridge ≈ 52.16 ft

Hello from MrBillDoesMath!
Answer:
P = ( sqrt(2)/2), sqrt(2)/2 )
Discussion:
The circle has a radius of 1 as passes it passes through the point (1,0). P makes an angle of 45 degrees with respect to the positive x axis, so by the Pythagorean theorem (or equivalently, trigonometry),
P = (x,y) = ( [email protected], [email protected]) = (1 cos(45), 1 sin(45)) =
( sqrt(2)/2), sqrt(2)/2)
Thank you,
MrB
