You show arrows because you are moving the decimal points to the right on both of them 2 spaces to the right to make one of them a whole number but in this case you are actually turning both of them into whole numbers. The number in the house must be either a whole number or a decimal but the number outside of the box must be a whole number, positive or negative.

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (0, 0)

Point (2, -3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m. Rate of change is the same as slope.

Substitute [SF]: $m=\frac{-3-0}{2-0}$
Subtract: $m=\frac{-3}{2}$

(98 pts + Brainliest) Question regarding logarithims and point slope form

bezimeni [28]

You are right in thinking that the base of the logarithm doesn't matter. It only affects the spread of the data points if you were to plot them, but would not ultimately have any effect on the slope of the line (but it would on the y-intercept).

One major discrepancy I'm noticing is in the values you found for $\ln\sin\theta$ . For example, if $\sin\theta=0.05$ , then you should have $\ln\sin\theta=\ln0.05\approx=-3.0$ . Not sure how you got -7.0, and the same goes for the rest of your table of values.

Another thing is that the provided solution suggests you take the average the first and last pairs of consecutive data points, and use these values in the slope formula to obtain the best-fit line's slope. If that's the case, then you should have

$\dfrac{\Delta\ln x}{\Delta\ln\sin\theta}=\dfrac{\frac{1.86+1.72}2-\frac{2.65+2.28}2}{\frac{-5.4-5.3}2-\frac{-7.0-6.4}2}=\dfrac{1.79-2.47}{-5.35+6.7}=\dfrac{-0.68}{1.35}\approx-0.5$

(i.e. you have to take the average of the given values, then use those averages in the $\Delta$ expressions - but this doesn't significantly affect the slope you found)

Ultimately, I think the problem is that your expression for the slope appears to be $\dfrac{\Delta\ln x}{\Delta\ln\sin\theta}$ , when the solution says it should be the reciprocal. I'm of the opinion that your slope is correct, since the experiment refers to $\theta$ (and hence $\sin\theta$ ) as the independent variable, and so $\Delta\ln\sin\theta$ would serve as the "run" and $\Delta\ln x$ would serve as the "rise".
