You need to prepare 50g of an ointment with 15% of zinc oxide. However, your pharmacy has no zinc oxide powder and the only thing you have is two lots of zinc oxide ointment containing, respectively, 50% and 5% of zinc oxide.
1. How many grams of the 50% ointment you need to prepare this formula?

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
