Answer:
For the first question: y = x^2
For the second question: y = x^2 - 2x + 1
For the third question: y = x^2 + 2x + 1
For the fourth question: y = x
For the fifth question: y = -x
Hope this helps:) Have a great day!
So multiply 2 x 1.10 = 2.20
3 x 95 = 2.85
5 x 2.15 = 10.75
Now add all that up 15.80 divide 15.80 by 5 to get 3 dollars and 16 cents(thats how much everyone pays)
or if your going to include tracy to the 5 people which would make 6 it would be 2.63333333333 so round that up to either 2.60 or 2.63
Since there is 16 cups in a US gallon, and there is 7 days in a week. First, you would multiply 1.5 times 7 getting 10.5 cups. But since that is not enough cups to be a gallon the division equation would look like this, 10.5/16 = ?. You can simplify it down to 5.25/8. Then, you get your answer of 0.65625 gallons.
A diagonal:
d = 70 in.
w² + h² = d²
w² + 42² = 70²
w² + 1764 = 4900
w² = 4900 - 1764 = 3136
w = √3136
w = 56
Answer: The width is 56 in.
