I think it's 0 since anything multiplied by 0 is, well, 0! No matter what the sign is. I believe the correct answer is 0 :)
Answer:
The correct option is C
Step-by-step explanation:
Given the circumference of circle which is 54 cm and also the measure of arc XY is 120°
we have to find the expression for arc length of XY
The arc length can be calculated by the formula



Hence, option C is correct
If one element in the domain mapped with more then one element in the range, the mapping is called one-to-many relation. One-to-many relations are not functions. Example: Draw a mapping diagram for the function f(x)=2x2+3 in the set of real numbers.
Step-by-step explanation:
The mean number of apples in each bag is 8. We have to calculate the number of apples in the 12 bag. Hence, there are 96 apples in 12 bags.
Set up the following equations:


x represents car A's speed, and y represents car B's speed.
We'll use elimination to solve this system of equations. Multiply the first equation by 7:


Combine both equations:

Divide both sides by 28 to get x by itself:

The speed of car A is
80 mph.Since we now know the value of one of the variables, we can plug it into the first equation:


Subtract 160 from both sides.

Divide both sides by 2 to get y by itself:

The speed of car B is
60 mph.
