Answer:
35) A. 21.2
46) D. 4/7
30) B. 4.4
42) C. Prism
Step-by-step explanation:
35) see first two attached files. 134.3 - 113.1 = 21.2
46) see third attached file. 4/7 = .5714 ish and 112 pi = 351.59 ish
30) see fourth attached file.
42) prisms are in no way circular so it cant have a circular base when cut
Already did this but may as well get the points haha
Answer:
![\boxed{\text{(6, 3)}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7B%286%2C%203%29%7D%7D)
Step-by-step explanation:
The conic form of the equation for a sideways parabola is
(y - k)² = 4p(x - h)
The focus is at (h + p, k)
The equation of Samara's parabola is
(y - 3)² = 8(x - 4)
h = 4
p = 8/4 = 2
k = 3
h + p = 6
So, the focus point of the satellite dish is at

Step-by-step explanation:
Answer:
x²+y²+4x-21=0
Step-by-step explanation:
(x-h)²+(y-k)²=r²
(x--2)²+(y-0)²=(5)²
(x+2)²+y²=25
x²+4x+4+y²=25
x²+y²+4x-21=0
