Area=pi*r^2
16/25 therefore is r^2
therefore r=4/5
circumference = 2*pi*r
8*pi/5 is the circumference, C.
Solution :
a).
1. The domain of C(x)
Range of c(x) is
Since the negative value do not make any sense.
2. C(x) = Ax + b
Intercept here denotes the fixed cost (that is when x = 0)
The slope indicates the marginal cost (that is increase in cost per unit of quantity)
3. Revenue is maximum marginal revenue = 0
(that is when at the top of the parabola)
4. Profit = R(x) -C(x)
5. Range of P(x) is important so that we have the idea in mind about the maximum loss and the maximum profit for a particular quantity.
6 and 7 -- insufficient data.
The outcome variable is also called the response or dependent variable, and the risk factors and confounders are called the predictors, or explanatory or independent variables. In regression analysis, the dependent variable is denoted "Y" and the independent variables are denoted by "X".
The answer is letter B
Since the line of the parabola is NOT included in the answer you cannot include any answer that lies on the line.
Answer: B
Step-by-step explanation:
Simplified- 0.88, 1.04, 1.75, 2.23
**0.9, 1.04, 1.8, 2.23** Rounded
