y = sqrt(9 * 16).
This formula is derived because of similar parts of similar right triangles.
It is called the geometric mean which you can google for right triangles that share a common side.
y = sqrt(144)
y = 12
D is the only possible answer.
=============
x = sqrt(9^2 + 12^2)
x = sqrt(81 + 144)
x = sqrt(225)
x = 15
=============
z = sqrt( (9 + 16)^2 - 15^2)
z = sqrt( 25^2 - 15^2)
z = sqrt(625 - 225)
z = sqrt(400)
z = 20
Answer D
z =

An elliptical mirror has an eccentricity of 0.8. The mirror is surrounded by a 2-inch wide golden frame and is 34 inches tall including the frame. If a replacement mirror is being cut from a rectangular sheet of glass, what is the minimum dimensions needed for the sheet of glass?

Answer:
y-intercept is -6
Step-by-step explanation:
this equation y=mx+b
so we only find the nu,ber the number in b
ex:b is 1, so 1is y-intercept
Answer:
Ok since u want to learn ill teach you :)
Get your 3 points and then your do this
Example= 3 power of 2 plus 5 power of 2
Then ur gonna add and get your answer hope this helps
(if u still don't get it ill just give u the answer)
7.2
Step-by-step explanation:
Hope u kinda got a good start on this :)
