To write and equation we call y=oil and x=vinager, so:
To find the constant k we can use the point in the picture (vinager, oil) = (x, y) = (1, 1.5), so:
So, the equation is:
Now, the meaning of the point (1, 1.5) is for 1 amount of vinager you need 1.5 amount of oil.
Answer:
A
Step-by-step explanation:
- to find x we use tan 60 = x/7
- rearrange, tan60*7 = x, x =
- now you have two sides so you can use pythagoras to find z
y^2 + x^2 = z^2
z =
z = 14
