Quadrilateral ABCD is inscribed in this circle.<br><br> What is the measure of angle A?

e-lub [12.9K]

Here’s an easy tip.
Always know that the angles next to each other, for example,AB, DC, AD& BC always equal to 180 degrees when added together.
So, we know that angle A plus angle B is 180.
Lets set it up.
2x+1+148=180
Combine like terms.
2x+ 149= 180
Subtract 149 from each side.
2x= 31
X= 15.5 degrees

If you horizontally stretch the quadratic parent function, f(x)= x^2, by a factor of 4, what is the equation of the new function

Sauron [17]

Answer:

$f(x) = \frac{1}{16}x^2$

Step-by-step explanation:

If the graph of the function $y=f(hx)$ represents the transformations made to the graph of $y= f(x)$ then, by definition:

If $0$ the graph is stretched horizontally by a factor $\frac{1}{h}$

If $h> 1$ the graph is compressed horizontally by a factor $\frac{1}{h}$

In this problem we have the parent function $y=x^2$ And we know that it stretches horizontally by a factor of 4

Therefore

$0$ and $h=\frac{1}{4}$

The transformation is:

$y=f(\frac{1}{4}x)$

And the function is:

$f(x) = (\frac{1}{4}x)^2$
