To do this you need the mean.
(81*9+70)/10 that is the mean equation.
Solve.
(799)/10
79.9
79.9% Will be your grade or a C
The removable discontinuity is at negative 6 and 6. Then the correct option is B.
<h3>What is a function?</h3>
The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.
The function is given as

The expression can be written as

Part B
Divide 63 by 3 to get 21, the price of one shirt.
Divide 21 by 7 to get 3, 10% of the original price.
Multiply 3 by 10 to get 30, the original price of one shirt.
Answer: $30
Part C
Divide 40 by 10 to get 4, 10% of original price
Multiply 4 by 3 to get 12, 30% of the original price
subtract 12 from 40 to get 28, the price after discount
Divide 28 by 10 to get 2.8, the second 10% discount.
Subtract 2.8 from 28 to get 25.2, the final price.
Answer: $25.20
Answer:
80π feet/ second.
Step-by-step explanation:
Angular velocity of a point = 10π radians per second
Radius of the circle is 8 feet.
We know the formula of angular velocity is
Angular velocity = 
10π = 
Speed = 80π feet/ second.
Option C is the answer.
