Answer:
It's surface area is 1257.14cm^2
Step-by-step explanation:
area=22/7×20cm×20cm
=3.14×20cm×20cm
=1257.14cm^2
Answer: 19
Step-by-step explanation:
Multiplying both sides of the equation by 
gives that 
.
Answer:
a very weak relationship between cost and volume
Step-by-step explanation:
The R factor is used to access the strength of the relationship between a dependent and independent variable. The R factor ranges between - 1 and 1. With negative values depicting a negative linear relationship and positive values meaning a positive relationship. The closer the R factor is to - 1 or + 1, the greater the strength, a value of 0 means, no correlation exists.
Hence, a R factor of 0.15 depicts a positive but very weak relationship between cost and volume as the R value is close to 0.
Answer:
18
Step-by-step explanation:
Answer:
Option D (2, 6)
Step-by-step explanation:
As shown in the graph function has four intervals on which graph is plotted.
1). From the graph we can see in the interval -10 ≤ x ≤ 0 graph is increasing.
2). From 0 ≤ x ≤ 2 function is decreasing.
3). Between 2 ≤ x ≤ 6 function is constant.
4). And for x ≥ 6 function is increasing.
Therefore interval in which the function is constant is (2, 6).
