The distance of the hiker of a linear function.

The true statement is <em>(d) The y-intercept is (0, 2), and the 2 represents the number of miles from the car at the start of this time period.</em>

From the graph, we can see that the graph crosses the y-axis at: (0,2)

This means that, the y-intercept is (0,2), and 2 represents the number of miles, he started with.

Hence, the correct statement is (d)

1-tan^2(x)/sec^2 = cos(2x)

LekaFEV [45]

By applying the formula of trigonometric function the right hand side will

be equal to right hand side which is 1- $tan^{2} x$ / $sec^{2}x$ =cos2x.

Given: 1- $tan^{2} x$ / $sec^{2}x$ =cos2x.

Taking right hand side first which is cos2x.

We know that cos2x= $1-tan^{2}x/1+tan^{2}x$

Now we will solve the left hand side of the equation give which is

1- $tan^{2} x$ / $sec^{2}x$

=1- $tan^{2}x$ /1+ $tan^{2}x$

[secant square x minus tangent square x is equal to 1]

By putting both values left hand side and right hand side we will find our solution which is :

1-tan^{2}x/1+tan^{2}x=1- $tan^{2}x$ /1+ $tan^{2}x$ .

Hence proved

compare the right-hand and left-hand derivatives to show that the function is not differentiable at the point P. find all points

Softa [21]

$f(x)= \left \{ {{ \sqrt{x} } \atop {2x-1}} \right. 
\\
\\ f'(x)= \left \{ {{ \frac{1}{2\sqrt{x}} } \atop {2}} \right. 
\\
\\ f'(1)= \left \{ {{ \frac{1}{2}} \atop {2}} \right. 
\\
\\ f'(1^-) \neq f'(1^+)$

Therefore, the function is not differentiable at x = 1.

$f(x)= \sqrt{x} 
\\
\\f'(x)= \frac{1}{2 \sqrt{x} } 
\\
\\f'(0)=\frac{1}{2 \sqrt{0} } = \infty$

Therefore, the function is not differentiable at x = 0.

Clara created the poster shown below:

lana66690 [7]

Answer:

$length=4\ cm\\width=6\ cm$

Step-by-step explanation:

Given the rectangular poster shown in the picture, you know that its dimensions (its width and its lenght) are:

$w_1=24\ cm\\l_1=16\ cm$

In order to calculate the dimensions of the rectangular at $\frac{1}{4}$ times its current size, you need to multiply the original lenght by $\frac{1}{4}$ and multiply the original width by $\frac{1}{4}$ .

Knowing this, you get:

$w_2=w_1\frac{1}{4}\\\\w_2=(24\ cm)(\frac{1}{4})\\\\w_2=6\ cm\\\\\\l_2=l_1\frac{1}{4}\\\\l_2=(16\ cm)(\frac{1}{4})\\\\l_2=4\ cm$
