Answer:
53.2 kg
Step-by-step explanation:
Let E represent Esther's weight. Then Henry's weight is E/2, and David's weight is E-5.2. Their average weight is ...
((E-5.2) + E + (E/2))/3 = 42.6
2.5E -5.2 = 127.8 . . . . . . . . . . multiply by 3, simplify
2.5E = 133 . . . . . . . . . . . . . . . . add 5.2
E = 133/2.5 = 53.2 . . . . kg
Esther's weight is 53.2 kg.
251+11x that’s the answer

Hello!
Interval notation is written using brackets or parentheses. Brackets mean that the value of the corresponding side is equal to the function. Parentheses are the opposite of brackets in this case, and it is not part of the equation.
I will post the graph of this equation below.
Therefore, the domain of this equation in interval notation is (-∞, 6/7).
Note that it is parentheses not brackets. The graph does not go past 6/7, and infinity is not a number, it is a concept.
Answer: 2.01%.
Step-by-step explanation:
Suppose Alex invests $1 into the account for one year. The formula is A=P0⋅(1+rk)N⋅k with P0=$1. We know that r=0.02 and k=2 compounding periods per year. Now, N=1 year. Substituting the values we have A=$1⋅(1+0.022)2=$1.0201. Now, to calculate the effective annual yield, we will use the formula rEFF=A−P0P0. rEFF=1.0201−11=0.0201 or 2.01%. When rounded to two decimals, rEFF=2.01%. However, do not include the % in your answer.
