Answer:
Look at the distances
Step-by-step explanation:
vertical and horizontal distances, see how far each vetex is from the center of the dilation. the dilation will be parrell to the image.
Answer: The span of the bridge is 59.77ft
Step-by-step explanation:
The standard form of equation for an ellipse with vertical major axis is:
(x-h)^2/b^2+(y-k)^2/a^2=1,a>b, (h,k)=(x,y) coordinates of center.
For given problem:
Place center of ellipse, (0,0) at center of bridge at ground level.
Given length of vertical major axis=70=2a
a=35
a^2=1225
Equation of an ellipse with horizontal major axis with center at (0,0)
Equation of ellipse:
x^2/b^2+y^2=1
plug in coordinates of given point on ellipse(27, 15)
27^2/b^2+15^2/a^2=1
729/b^2+225/1225=1
729/b^2=1-225/1225= 0.816
b^2=729/0.816≈ 893
b≈29.88
length of minor axis=2b≈59.77 ft
span of bridge≈59.77 ft
In any inequality or equation, a number that does not change is called a constant.
Answer:
Let me know if you want more explanation
Step-by-step explanation:
Alright, to solve for x we need 2 angles that are congruent or equal.
I'm going to use the two we will need later. KLN and MNL
Now to find x ^^
Now we just need to plug it into each angle. I'm going to show you them separately.
should be right now.
The hypotenuse is the longer of the 3 sides:
answer: b.26
