Please explain! <br><br> 1/2x+1/8y=3<br><br> Solve in Slope Intercept form.
charle [14.2K]

Answer:

y = 4x + 24

Step-by-step explanation:

The slope is the number in front of the x-value.

Slope intercept form is in the form of

y = mx + b  (or as how I learned it)

m is the slope, and b is the y-intercept (the number that is left on the side.)

You can rearrange this by moving the x to the right side by subtracting it from both sides.

You now have 1/8y = 3 - 1/2x

which can be rearranged to

1/8y = -1/2x + 3.

You need to change the y to 1 whole instead of 1/8, so you multiply it by 8 since 8 divided by 8 is 1.

y = -4x + 24

If a sequence c1,c2,c3,...has limit K then the sequence ec1,ec2,ec3,...has limit e^K. Use this fact together with l'Hopital's ru
aleksandrvk [35]

Answer:

Step-by-step explanation:

If a sequence c1,c2,c3,...has limit K then the sequence ec1,ec2,ec3,...has limit e^K. Use this fact together with l'Hopital's rule to compute the limit of the sequence given by

bn=(n)^(5.6/n).

a)

L =  \lim_{n \to \infty} b_n \\\\\\L= \lim_{n \to \infty} n^{\frac{5.6}{n} }

Log on both sides

In (L) =  \lim_{n \to \infty} In (n)^{\frac{5.6}{n} }\\\\= \lim_{n \to \infty} \frac{5.6}{n} In(n)

=5.6 \lim_{n \to \infty} \frac{d}{dn}  In(n)/\frac{d}{dn} (n)\\\\=5.6 \lim_{n \to \infty} \frac{1}{n} /1 \\\\=5.6 \lim_{n \to \infty} \frac{1}{n} \\\\=5.6 \times 0\\\\In(L) =0\\\\L=e^0\\\\L=1

\therefore  \lim_{n \to \infty} (n)^{\frac{5.6}{n} =1

The arm span and foot length were measured (in centimeters) for each of the 19 students in a statistics class and displayed in t
erica [24]

Based on the computer output of the scatter plot, the predicted foot length for a student with an arm span of 160 cm is: B. 22.15 cm.

<h3>What are Scatterplots?</h3>
  • Scatter plot is a graphical tool that shows a trend between a dependent and independent variable.
  • The trend line can be used to make predictions.

Given the scatter plot as shown above, at 160 cm arm length spam, if we trace it up to the trend line, the corresponding predicted foot length lies between 21 - 23 cm.

Therefore, based on the computer output of the scatter plot, the predicted foot length for a student with an arm span of 160 cm is: B. 22.15 cm.
