Goblin Green Paint is made by mixing blue and yellow paint in the ratio 4 to 3. Show and discuss at least four different ways to represent varying quantities of blue and yellow paint that will mix to make Goblin Green Paint. (These can include ways discussed in previous sections.) Discuss which aspects of proportional relationships are easier to see in some ways than in others.

Explain the errors that were made or the formulas that were misused.Part B: Complete the student's solution correctly, beginning with the location of the error.arrow_forward
- Although 330° is a special angle on the unit circle, Amar wanted to determine its coordinates using the sum and difference formulas.Part A: Determine cos 330° using the cosine sum identity. Be sure to include all necessary work.Part B: Determine sin 330° using the sine difference identity. Be sure to include all necessary work.arrow_forwardA public health researcher is studying the impacts of nudge marketing techniques on shoppers vegetablesarrow_forward4. Let A {w, e, s, t, f, i, e, l, d, s, t, a, t, e}. (a) How many different words (they do not have to make sense) can you spell with the letters in A?

For example 124 is ok, 122 is not ok. Every digit can be used only once, but you do not have to use every digit. A tree might help.arrow_forward5 plsarrow_forward
