Using hit and trial, you van find it pretty easily-
- Putting x=0, we get y=-3
- Putting x=1, we get y=-1
- Putting x=2, we get y=5
You can try it for yourself as well, for me, I couldn't find any other option appropriate.
The constant of proportionality is: 0.2 and the equation is: c = 0.2t
Step-by-step explanation:
Let t be the number of texts and c be the cost
Then according to given statement
c ∝ t
The proportionality symbol will be removed and a constant f proportionality will be introduced.
<u>For constant of proportionality:</u>
Hence the constant of proportionality is 0.2

The distance between two points (4,-2) and (-6,4) exists
<h3>How to estimate the distance between two points?</h3>
Distance between two points exists the length of the line segment that joins the two given points. Distance between two points in coordinate geometry can be estimated by finding the length of the line segment merging the provided coordinates.
Let the points be (4,-2) and (-6,4).
The distance between two points and exists provided by the distance between the two points
substituting the points in the equation, we get
simplifying the equation, we get
The distance between two points (4,-2) and (-6,4) exists
Therefore, the correct answer is option c.

Answer:
a) weights: 0.32688, 0.18402, 0.35593, 0.13317
b) geometric average return: 5.42%
Step-by-step explanation:
The total of amounts invested is ...
13500 +7600 +14700 +5500 = 41300
The respective weights for the weighted average are these values divided by the total. For example, 13500/41300 ≈ 0.32688. The remaining weight values are shown in the attached spreadsheet.
The weighted geometric average return is 1 less than the product of 1 more than the individual returns raised to the power of the weight*. That is, ...
weighted average return
= (1.097^0.327)(1.124^0.184)(0.945^0.356)(1.172^0.133) -1
= 1.0542 -1 = 5.42%
_____
* Technically, the weighted geometric average is root of the products of the values to the power of the weight. The root index is the sum of the weights. Here, the sum of weights is 1, so the root is simply the product itself.
