Answer:

x = \frac{8}{5}

Step-by-step explanation:

Given

\frac{13x+12x}{4} = 10 ( multiply both sides by 4 to clear the fraction )

25x = 40 ( divide both sides by 25 )

x = \frac{40}{25} = \frac{8}{5}

Answer:

1.61*10^{8} \\and\\3.3*10^{-7}

Step-by-step explanation:

We can use properties of exponents to solve these equations. Remember that when multiplying exponents, we 'add' them.

--------------------------------------

(2.3*10^{1})(7*10^{6})= \\16.1*10^{7}=\\1.61 *10^{8}

For the next question:

(1.1*10^{-5})(3*10^{-2})=\\ 3.3*10^{-7}

These are your answers!

Which transformation are needed to change the parent cosine function to y=3cos(10(x-pi))
BlackZzzverrR [31]

Answer:


Step-by-step explanation:

First, we can transform y = cos(x) to y = 3*cos(x) by stretching the graph vertically by a factor of 3. At x = 0, the y value would now be 3 * 1 = 3 instead of 1 (the stretching would cause all new y-values to be 3 times their original values for any given x).  

Now transforming y = 3*cos(x) to y = 3*cos(10*x) will stretch the graph horizontally by a factor of 10 (for any given y value, the new x value corresponding to it is 10 times the original x value).

Finally, to transform y = 3*cos(10*x) to y = 3*cos(10(x-pi)), shift the graph to the right by pi.
