Find the tangent line equation of the curve at the given point. Y=arcsin(7x) at the point where x=sqrt2/14
Mumz [18]

Answer:

Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})

Step-by-step explanation:

The equation of the curve is

Y = sin^{-1}(7x)

To find the equation of tangent we need to differentiate this equation w.r.t x

So, differentiating we get

Y'=\frac{7}{\sqrt{1-49x^2} }

This would give the slope of the tangent line at any given point of which x coordinate is known. In the present case it is  x = \sqrt{\frac{1}{7} }

Then slope would accordingly be

Y'=\frac{7}{\sqrt{1-49/49} }

= ∞

For, x = \sqrt{\frac{1}{7} }, Y = sin^{-1}(7/7)= \pi/2

Equation of tangent line, in the point slope form, would be Y-\frac{\pi}{2} =\frac{\pi}{2} (x+\sqrt{\frac{1}{7}})

Answer:

Step-by-step explanation:

   Hours: 1      5         10      15      20         25

Minutes: 60   300   600   900   1,200     1,500

These show proportional relationship because they are all times hour by 60 minutes and the hours go by 5 hours, each.

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they spend on soc
kolbaska11 [484]
First I let's represent our data in the table and make a scatter plot ( i attached the image).
\begin{tabular}{ll} x & y \\ 0.5 & 100 \\ 2 & 100 \\ 1 & 95 \\ 3 & 85 \\ 3 & 78 \\ 5 & 75 \\ 5 & 72 \\ 6 & 70 \\ 6 & 98 \\ 7 & 60 \\ \end
Points labeled A are called data set.
Point labelled B is called the outlier. The outlier is a point that does not fit well with the rest of our data set. Posible reason for point B is that someone is super smart and they don't need to spend a lot of time studying to achieve good results.
PartB
We can see from the graph that the number of hours spent on social media and test scores are negatively correlated. See a scatter plot, I added the trend line.
In other words, the more hours you spend on social media the lower your test scores should be.

Describing Key Features of a Graph of a Polynomial Function:
Diano4ka-milaya [45]

<u>End behavior: </u>

The parent function is: f(x) = x³, which starts (from the left side) at -∞ and ends (on the right side) at +∞.

<u>Zeroes:</u>

f(x) = x³ + 2x² - 8x

0 = x³ + 2x² - 8x

0 = x(x² + 2x - 8)    

0 = x(x + 4)(x - 2)

0 = x         0 = x + 4         0 = x - 2

x = 0            x = -4              x = 2

<u>Intervals:</u>

Put the zeroes in order: -4, 0, 2

since f(x) is increasing from the left then the interval from -4 to 0 is positive and the interval from 0 to 2 is negative.

<u>Graph:</u>
