Answer:
<4
Step-by-step explanation:
The vertex of the angle is on the lighthouse and one ray/angle is on the boat.
Answer:
Step-by-step explanation:
The formula for volume of a cylinder is..
V = πr²h where r is the radius and h is the height. We are given V = 452 and h = 9, plug those values in and solve for r
452 = πr²(9)
452/(9π) = r² (divide both sides by 9π)
√[452/(9π)] = r (take the square root of both sides)
(√452)/(√9π) = r (the next steps simplify the equation)
(2√113)/(3√π) = r
[(2√113)√π)]/[3(√π)(√π)] = r
[2√(113π)]/(3π) = r
Answer:
(x - y) (x+y -1)
Step-by-step explanation:
<u>See steps of factorization:</u>
- x² - y² - x + y =
- (x² - y²) - (x - y) =
- (x - y) (x + y) - (x- y) =
- (x - y) (x+y -1)
Answer:
An inherent zero is a zero that implies none
Step-by-step explanation:
A zero which means that a phenomenon or variable does not exist or isn't represented is called inherent zero. It simply implies none.
Datasets that have inherent Zero:
1. Average age of participants In years
2.) Rainfall height in inches during rainy period
3.) Speed of wind during a storm.
Datasets with no inherent zero :
Dataset which involves measuring constructs usually have no inherent zero, such as :
1.) Average IQ level in a group of students
2.) Average level of satisfaction
3.) measurement involving temperature
