: Let y = f(x) = x^1/3
Then dy = 1/3*x^(−2/3) dx
Since f(64) = 4.
We take x = 64 and dx = ∆x = 1
This gives dy = 1/3*(64)^(−2/3)* (1) = 1/48
∴65^(1/3) = f(64 + 1) ≈ f(64) + dy = 4 + 1/48 ≈ 4.021 <span>

tangent
Step-by-step explanation:
because it gave u an angel and and adjacent so your x is the opposite so sin20=x÷17 just use your calculator u will find the ans
Answer:
8 pounds of 4% solution of borax
Step-by-step explanation:
Let x be the 4% solution
24 pounds of 12% solution
obtain a 10% solution of borax that is (x+24) pounds
4% is 0.04 and 12% is 0.12 , 10% is 0.1

solve the equation for x

so 8 pounds of 4% solution of borax
