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.

Answer to this math question
gladu [14]

Answer:

4\frac{2}{3}

Step-by-step explanation:

This is a recurring decimal.

Let x = 4.666666...                 ⇒ (1)

  10x = 46.66666...                     ⇒ (2)

Subtract equation (1) from equation (2)

    10x = 46.66666..

   -<u>  x = 4.666666...  </u>

    <u>  9x = 42.0000.....</u>

<u />

9x = 42

  x =  42/9

      = 14/3

       =4\frac{2}{3}

What is the perimeter of a rectangle with a length of 22 and a width of 68.8?
lakkis [162]
Perimeter = (2 lengths) + (2 widths) or 2(length + width).

2 (22 + 68.8) = 2 (90.8) = <u>181.6</u>

Write the equation in y=(your answer) y is the y axis in coordinate plane.
Vitek1552 [10]

Answer:

y = 4

Step-by-step explanation:

Given the equation of the line, y = 6, passing through point (3, 4):

By definition, parallel lines have the <u>same slope</u>.

The linear equation, y = 6 is a horizontal line with a zero slope. Therefore, the parallel line must also have the same slope = 0.

Plug the given values from the point (3, 4) into the slope-intercept form:

y = mx + b

where:  y = 4, m = 0, and x = 3. We need to solve for the y-intercept, b:

y = mx + b

4 = 0(3) + b

4 = 0 + b

4 = b  

Therefore, the y-intercept is (0, 4).

For horizontal lines, the y-coordinate = 4 stays the same, while having different x-coordinates.

Therefore, the equation that is parallel to y = 6 is y = 4.
