130.1 because 1 rounds down to 0 it isn't over 5
Hello.
1. Switch y and x.
x = 10y^2 - 4
2. Isolate y.
x + 4 = 10y^2
(x + 4)/(10) = y^2
y = sqrt[(x + 4)/(10)]
3. Replace y with f^-1(x)
f^-1(x) = sqrt[(x + 4)/(10)]
Good luck to you!
Answer:
use the firmula
area of triangle =1/2b×h
Step-by-step explanation:
let the ratio be 6x and 5x
- 6x+5x=135
- now solve this
- this may help you
LA = (2l + 2w)h
Plug in what we know:
LA = (2(11) + 2(7))(4)
Multiply:
LA = (22 + 14)(4)
Add:
LA = 36(4)
Multiply:
LA = 144
