Actually, you have to find four missed terms of geometrical sequence. Denote
and r - ratio, then
.
Since 
, you have that 
, then
.
Now substitude r=2 in each of unknown 4 terms:
.
Answer: four geometric means between 25 and 800 are 50, 100, 200, 400.
Let's put it this way: If you plot a few non-x-intercept points and then draw a curvy line through them,you will not know if you got the x-intercepts even close to being correct. <span>The only way you can be sure of your x-intercepts is to set the quadratic equal to zero and solve. So its a matter of guessing from the pictures. Basicaly said, the calculator won't give you the exact result.</span>
Answer:
(f o g)(x) = -2x² - x + 4
Step-by-step explanation:
f(x) = -x + 6
g(x) = 2x² + x + 2
To find (f o g)(x), you need put g(x) into f(x).
f(x) = -x + 6
(f o g)(x) = -(2x² + x + 2) + 6
(f o g)(x) = -2x² - x - 2 + 6
(f o g)(x) = -2x² - x + 4
Answer:
m+n=140
Step-by-step explanation:
So the angles in a triangle always add up to 180. We already know that the first angle in the triangle is 40 degrees because it's shown in the angle below the triangle. So we have 140 degrees left since 40 is taken up. That eans m+n=140
