EXPLANATION
The given parametric equations are:
and
We make t the subject in the first equation to obtain:
We substitute this into the second equation to get:
When x=1,
When x=2
When x=7,
Therefore the points (1,2) and (7,2) lie on the given curve.
Answer:
65 servings
Step-by-step explanation:
Larry made 5 batches of punch.
In each batch, she uses the amount of lemon juice = 24 fluid ounces
and the amount she uses of orange juice = 5 pints
Since 1 pint = 16 fluid ounces
∴ 5 pints = 16 × 5 = 80 fluid ounces
Total quantity of punch in each batch = 24 + 80
= 104 fluid ounces
Total quantity of punch in 5 batches = 104 × 5
= 520 fluid ounces
If each serving is 1 cup.
and 1 cup = 8 ounces
He made the number of servings all together =
= 65 cups
He made 65 servings all together.
