Ah is derived from h^2. it's derivative is 2h^2-1, thus the constant a = 2
b is derived from bh. where it's derivative is h^1-1, thus the constant b = 1
Uh for the second question, his height in decimal form would be 4.75, kind sir.
Hope this helped,
Answer:
Step-by-step explanation:
Let q represent the number of quarters Theresa has. Then the value of her coins is ...
0.25q + 0.10(20 -q) = 2.75
0.15q = 0.75 . . . . . . . . . subtract 2.00, collect terms
q = 0.75/0.15 = 5
Theresa has 5 quarters and 15 dimes.
For this case we must simplify the following expression:
We eliminate the parentheses taking into account that:

So:

We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.
