Answer: 8.4
Explanation: Substitute y = 0.8 into the equation.
4x + 8(0.8) = 40
4x + 6.4 = 40
4x = 33.6
x = 8.4
Answer:
The highest you could reach with this ladder is 30 feet or 9.14 meters.
Its like a polynomial.
cosx=x
so it'll be like
2x^2+3x-2=0
<span>(2x−1)(x+2)
</span>
which makes your life easy because you do not have to solve cos(x)=−2 because it cannot be, so only solve cos(x)=1/2
