Answer:
6x² - 2x - 6
Step-by-step explanation:
note (f - g)(x) = f(x) - g(x), thus
f(x) - g(x)
= 6x² - 4 - (2x + 2) ← distribute
= 6x² - 4 - 2x - 2 ← collect like terms
= 6x² - 2x - 6
Answer:
4(9x^4+1858)
Step-by-step explanation:
36 x^4 + 18^3 + 40^2
36x^4+7432
4(9x^4+1858)
In a survey with 60 people, each people would get 1/60th of the chart which has 360 degrees, so everyone would get 360/60=6 degrees
and 13 people would get 13*6=78 degrees!
Answer:
B
Step-by-step explanation:
Remark
If we draw a line from F to T, we can make a couple of statements.
Call the center of the circle O
1. <FTE = 1/2 the central angle of <FOE. The size of <FOE is the same size as the minor arc. Since The minor arc = 60 degrees, then FTE = 30 degrees.
2. <GTF = 1/2 78 by the same reasoning used above. GTF = 39 because that is 1/2 of 78.
So the answer to the size of <T = 39 + 30 = 69 which is B
There is a much simpler way of doing this.
The central angle of the two arcs is 78 + 60 = 138
The <GTE is 1/2 the central angle
<GTE = 1/2 * 138 = 69
