The highway mileage m in miles per gallon for a compact car is approximated by m(s) = -0.025s^2 + 2.45s - 30, where s is the spe
Over [174]
The maximum mileage per gallon for the compact car is determined by taking the first derivative of the given equation and equate to zero. The differentiated form is m's = -0.05 s + 2.45 = 0; s is equal to 49 seconds. substituting this s, m is equal to 30.025 miles/gallon.

Answer: note I will just replace the Shape by an X

a) X + 9 = 9 + 6; X=6 Commutative Propertie

b) 0 + X = 7;  X=7  Additive Identity Propertie

c) X + (7 + 3) = (4 + 7) + 3; X=4   Associative Propertie


Step-by-step explanation:

There are four mathematical properties which involve addition. Commutative, associative, additive identity and distributive properties.

Commutative property: When two numbers are added, the sum is the same regardless of the order of the addends.  

Associative Property: When three or more numbers are added, the sum is the same regardless of the grouping of the addends.  

Additive Identity Property: The sum of any number and zero is the original number.  

Distributive property: The sum of two numbers times a third number is equal to the sum of each addend times the third number.
