<span>My answer -
f(x)=x^3+2
To find the inverse function f(x)^-1 , we will assume"
y=x^3+2
y-2= x^3
==> x= (y-2)^1/3
==> f(x)-1= (x-2)^1/3</span>
P.S
Happy to help you have an AWESOME!!!!! day
Answer:
Step-by-step explanation:
We would apply the law of Cosines which is expressed as
a² = b² + c² - 2abCosA
Where a,b and c are the length of each side of the triangle and A is the angle corresponding to a. Likening the expression to the given triangle, it becomes
JK² = JL² + KL² - 2(JL × KL)Cos10
JK² = 61² + 53² - 2(61 × 53)Cos10
JK² = 3721 + 2809 - 6466Cos10
JK² = 6530 - 6367.767
JK² = 162.233
Taking square root of both sides of the equation, it becomes
JK = √162.233
JK = 12.73 to the nearest tenth
Solution1 Add <span>88</span> to both sides

2 Simplify <span>10+8<span>10+8</span></span> to <span>18<span>18</span></span>
<span>3x=18<span>3x=18</span></span>
3 Divide both sides by <span>33</span>
