Answer:
<em>Riko is wrong because she uses the wrong formula.</em>
Step-by-step explanation:
Given the coordinate points (-2, -3) and (2, -5)
We are to find the distance between the two points
Using the formula:
D = √(x2-x1)²+(y2-y1)²
From the coordinates x1 = -2, y1 = -3, x2 = 2 and y2 = -5
Substitute
D = √(2-(-2))²+(-5-(-3))²
D= √(4)²+(-2)²
D = √16 + 4
D = √20
D = √4*√5
D = 2√5
<em>This shows that Riko is wrong because she uses the wrong formula.</em>
The answer is choice “Yes”
Step-by-step explanation:
k/4=33/20
k=33/20×4
k=33/5
Answer:
1) The graph is linear, because it has an upwards slope of 5, we can tell because 3*5 =15 and 6*5=30.
2)Real world meaning is the delta change. Hence in this case it's the increase in rain over time. More rain or raining harder as time progresses.
3)It is not linear because the second sample shows a slope of 7.5 meanwhile the third sample shows a slope of 6 which allows us to conclude that it is not linear.
4)The y intercept means the total rain that was present at the start of the recording which essentially means there was no rain when she started the experiment.
The answer is: [B]: 3.

Let us assume that the problem is meant to be written as:
_______________________________________________
2a / (3b - c) ;
Explanation:
___________________
we are given the values for "a", "b", "c" ; and we are asked to solve the problem when the given values:
a = 6, b = 4; and c = 8 .
________________________
Note:
________________________
We have a "numerator" , " 2a " ; and a "denominator" , (3b - c).
_______________________
Let us start by finding the numerator:
_________________________________
Numerator: 2a = 2*a = 2 * 6 = 12.
_______________________________________
Denominator: 3b - c = (3*4) - 8 = 12 - 8 = 4
_______________________________________
To solve: Numerator ÷ Denominator = 12 <span>÷ 4 = 3.
_______________________________________
The answer is: [B]: 3.
