Answer:
1 1/8 Cups of flour are needed for 1 fruitcake.
Step-by-step explanation:
This is because if you divide 4 1/2(the amount of flour used for four cups) by 4 (the amount of fruitcakes he made) you would get 9/8 or 1 1/8 which is what you use for 1 fruitcake. I hope this helped!
Plug in D:
-4(1)^2 + 15(1)^2/5
-4 + 15 / 5
-4 + 3 = -1
0
Arc sec(1)=0, tan(0)=0
The scale factor is 1.5! I hope this helps!
