  • Product Rule of Radicals: √ab = √a × √b

So firstly, factor out i (i = √-1):

10i√80

Next, apply the product rule of radicals and simplify the radical as such:

√80 = √10 × √8 = √5 × √2 × √4 × √2 = 2 × 2 × √5 = 4√5

10i × 4√5 = 40i√5

<u>Your final answer is 40i√5.</u>

How do I graph f(x)= -cos(x-pi)?
Lorico [155]
Just exactly as you graph any other function: List a bunch of values for 'x', find the value of the function for each one, and start graphing the points, until you have enough points to see the shape of the function, and can draw more of it without more points. When you do that, you'll discover that -cos (x-pi) is equal to cos (x).

If a line goes through the point (8,9) and has a slope of negative 3/4 what is the starting value?
scZoUnD [109]

I assume by starting value, you mean y-intercept. The y-intercept is 15

To find this, we need to use slope intercept form and the given information to find it.

y = mx + b ----> plug in the known values

9 = -3/4(8) + b

9 = -6 + b

15 = b

Therefore, the starting value is 15.

earnstyle [38]
 Line r represents  the equation y= 3x-2.
Even though the y-intercept is not visible, the slope is 3. So that means the orange line is the equation
