Mary is twice as old as jean and seven years older than hazel. The sum of their ages is 53. How old is each person?
weeeeeb [17]

Answer:

Step-by-step explanation:

M = 2J

M = H + 7

M + J + H = 53

Then combine first two equations and solve in terms of J:

2J = H + 7 --> H = 2J - 7

Substitute for H & M in last equation:

2J + J + 2J - 7 = 53

5J - 7 = 53

5J = 60

J = 12

Then plug J into other equations:

M = 24

J =12

H = 17

Calculus help needed!
mezya [45]

f(x)=\ln x\\\\g(x)=\ln11x=\ln11+\ln x\ \ (\ln11=const.)\\\\h(x)=\ln x^2=2\ln x\\\\p(x)=\ln3x^2=\ln 3+\ln x^2=\ln3+2\ln x\ \ (\ln3=const.)

Used:

\ln a+\ln b=\ln(ab)\\\\\ln a^n=n\log a


Functions have the same derivatives if they differ a constant.

h(x) = f(x); g(x) = f(x) + const.

h'(x) = f'(x)

g'(x) = (f(x) + const.)' = f'(x) + (const.)' = f'(x) + 0 = f'(x)

h'(x) = g'(x)


Therefore yuor answer is A. f'(x)=g'(x)



f'(x)=(\ln x)'=\dfrac{1}{x}\\\\g'(x)=(\ln11x)=\dfrac{1}{11x}\cdot11=\dfrac{1}{x}

Used:

(\ln x)'=\dfrac{1}{x}\\\\f'(g(x))=f'(g(x))\cdot g'(x)
