C. y= -28/x
y=k/x
cross multiply
k= y×x
k = -2×14
k = -28
y = -28/x [ equation connecting x and y]
Answer:
B and C
Step-by-step explanation:
Sin 45 or Cosine 45.
They are already rounded?; unless you need to round lower
Answer:
They are congruent
Step-by-step explanation:
Answer:
![x=49/4](https://tex.z-dn.net/?f=x%3D49%2F4)
Step-by-step explanation:
we know that
If two figures are similar, the the ratio of its corresponding sides is equal
In this problem we have
smaller cone
![r1=8/2=4\ units](https://tex.z-dn.net/?f=r1%3D8%2F2%3D4%5C%20units)
![h1=7\ units](https://tex.z-dn.net/?f=h1%3D7%5C%20units)
larger cone
![r2=7\ units](https://tex.z-dn.net/?f=r2%3D7%5C%20units)
![h2=x\ units](https://tex.z-dn.net/?f=h2%3Dx%5C%20units)
so
![\frac{h2}{h1}=\frac{r2}{r1}](https://tex.z-dn.net/?f=%5Cfrac%7Bh2%7D%7Bh1%7D%3D%5Cfrac%7Br2%7D%7Br1%7D)
![\frac{x}{7}=\frac{7}{4}\\ \\x=7*7/4\\ \\x=49/4](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B7%7D%3D%5Cfrac%7B7%7D%7B4%7D%5C%5C%20%5C%5Cx%3D7%2A7%2F4%5C%5C%20%5C%5Cx%3D49%2F4)
