Answer: Function, not a function, Function, not a function
Step-by-step explanation:
For it to be a function, each value of x has to map onto one value of y.
- This is a function.
- Not a function since x=-1 has more than one y value.
- This is a function
- Not a function since x=-6 has more than one y value.
Answer:
D.) If soccer balls are sold for $2.05 or $14.61 each, the store will break even but will not make a profit.
Step-by-step explanation:
Let us assume x = selling price of each soccer ball
y = daily profit earned from selling of soccer balls
Given that
Y= 
where,
a = -6
b = 100
c = -180
Now we have to applied the formula which is as follows
x 
x^1 = -2.05285
Now
x^2 
x^2 = 14.6138
Based on this the option D is most appropriate as per the given situation
Consider the angles are = 60,2x,3x
As we know the sum of the interior angle of a triangle is 180
60+2x+3x= 180
5x= 120
x= 24°
Angles are 2x= 2(24)= 48°
and 3x= 72°
<em>The measure of smaller angle is 48°</em>
Answer: B. same distance
There is the same distance between the point on the preimage to the center of rotation and that of the distance from the corresponding point on the image to the center of rotation. There is change in the distance of the two.
