Answer:
B
Step-by-step explanation:
3*5 is 15 and since its a negative 5 your answer will be negative
Answer:
16.24 Units
Step-by-step explanation:
The perimeter of the triangle is the sum of the length of the sides of the triangle. Given the points on the vertices, the length of each side may be found using the formula
Length = √(x2 - x1)^2 + (y2 - y1)^2
Considering the pair (-1, 2), (3, 1), the length of that side
= √(3 -- 1)^2 + (1-2)^2)
= √(16 + 1)
= √17 units
Considering the pair (-1, 2), (7, 2), the length of that side
= √(7 -- 1)^2 + (2-2)^2)
= √(64)
= 8
Considering the pair (3, 1), and (7, 2), the length of that side
= √(7 - 3)^2 + (2 - 1)^2
= √(16 + 1)
= √17
Hence the perimeter of the triangle
= √17 + 8 + √17
= 4.12 + 8 + 4.12
= 16.24 Units
Answer: The correct answer is: quadratic, because the height increases and then decreases
We are given the below data:
Time (seconds) Height (feet)
0 5
1 50
2 70
3 48
4 4
We know that quadratic model is used in situations when the values increase and then decreases.
Looking at the given, we clearly see the height variable first increase and then goes on decreasing as the time in seconds increases. Therefore, the appropriate model would be quadratic model here and the correct option is:
quadratic, because the height increases and then decreases
1/5 chance of choosing the number 8 than an odd number
The following statements are always true:
- X + Y is a whole number:
- X • Y is a whole number:
While the following statements are sometimes true
- X - Y is a whole number:
- W + Z is a whole number:
- Y + Z is a rational number:
- Y • W is a rational number:
- X % Z is a rational number:
<h3>How to determine whether the following statements are always, sometimes, or never true?</h3>
The given parameters are:
- Whole numbers = x and y
- Rational numbers = w and z
The sum and products of whole numbers are always whole numbers.
This means that, the following statements are always true:
X + Y is a whole number:
X • Y is a whole number:
While the following statements are sometimes true
X - Y is a whole number:
W + Z is a whole number:
Y + Z is a rational number:
Y • W is a rational number:
X % Z is a rational number:
