Answer:
Maybe 74
Step-by-step explanation:
42+64=106
180-106=74
K.E=0.5mv^2
GPE=mgh
The child has both K.E and GPE


g is taken as 9.81
The rule for differentiation for variable with exponents has the formula:
d/dx (xⁿ) = nxⁿ⁻¹
where n is the exponent
Thus, for the given equation, the solution is as follows:
y = 2x²
dy/dx = 2(2)x²⁻¹ = <em>4x
Thus, the derived equation of the given would now be 4x.</em>
