It should be C on a Friday
Answer:
Each property is mentioned with the corresponding expression.
Step-by-step explanation:
Writing the property in front of every expression:
1. Additive Identity: 11+0 = 11
2. Associative Property of Multiplication: x*(y*z) = (x*y)*z
3. Additive Identity: 8+(-8) = 0
4. Commutative property of Addition: 14+20=20+14
5. Multiplicative Inverse: 2*1/2 = 1
6. Multiplicative Identity : 22*1 = 22
7. Associative Property of Addition: (19+12)+8=19+(12+8)
8. Commutative Property of Multiplication: a*9=9*a
9. Distributive Property: 7(4+11) = 7(4)+7(11)
The answer is -2
5 - 7 = -2
Actually it's not 1
330 in 4th quadratic is just 30 in 1st and cos is +ve
so you have
sqrt(3)/2 ^2 = 3/4 = 0.75
B. cost(distance) is the right answer
Step-by-step explanation:
We are given that the cost is dependent on the distance traveled.
There are two types of variables.
Independent and dependent variables
Independent variable is the variable whose value is independent of any variable in the function while the dependent variable is determined by changing the values of independent variable
In the given scenario, cost is a dependent variable and distance traveled is independent.
When function notation is written, the independent variable is written inside the round brackets. In this case,
cost(distance) as cost is dependent on distance
Hence,
B. cost(distance) is the right answer
