Answer:
60000 square miles
Step-by-step explanation:
Step 1: Great lakes beginning with consonant: Huron, Michigan, Superior
Great lakes beginning with vowel: Ontario, Erie
Step 2: Estimate the areas to nearest thousand.
Estimation of area of Huron = 23000 square miles
Estimation of area of Michigan = 22000 square miles
Estimation of area of Superior = 32000 square miles
Total area of Great lakes beginning with a consonant = 23000 + 22000 + 32000 = 77000 square miles
Estimation of area of Ontario = 7000 square miles
Estimation of area of Erie = 10000 square miles
Total area of Great lakes beginning with a vowel = 7000 + 10000 = 17000 square miles
Step 3: Difference between the total area of Great lakes beginning with a consonant and the vowel
77000 – 17000 = 60000 square miles

Answer:
Step-by-step explanation:
y = ax² + bx + c
Plug the points into the equation to get a system of 3 equations with 3 unknowns a, b, and c.
-27 = 4a - 2b + c
-42 = 9a + 3b + c
-12 = a + b + c
(a,b,c) = (-4,1,-9)
y = -4x² + x - 9
