10=25
Step-by-step explanation:
40=100
4=10
2=5
<span>(a) the slope of curve is calculated from the derivative of the curve expression y=5/x. In this problem, the slope m=-5/(a^2).
(b) x=1, y=5，and m=-5, the tangent line is y-5=-5*(x-1).
x=4, y=5/4, and m=-5/16, the tangent line is y-5/4=-5/16*(x-4)</span>
X=11 because 90-43+5x-8 so 5•11=55-8 =47 90-43=47
