The function, when graphed, looks like this:
Answer:
0
Step-by-step explanation:
Let's find f(3) first
All we need to do is plug 3 in the place of x
2(3) - 3
6 - 3 = 3
Now let's find f(0)
Do the same thing for the first one, plug the new number in the place of x
2(0) - 3 = -3
Not add both answers up
3 + -3 = 0
The numbers are -6 and -11 .
-11+-6=-17
-11 times -6 = 66
A negative times a negative equals a positive.
Answer:
50; 72; 8; 57.9
Step-by-step explanation:
1. sqrt((30/2)^2 + (20)^2) = sqrt(15^2 + 20^2) = sqrt(225 + 400) = sqrt(625) = 25 (radius) * 2 = 50 (diameter)
2. 360 (degrees in a circle)/5 (sides in a pentagon) = 72 degrees
3. 360 (degrees in a circle)/x (sides) = 45 --> 360/45 = x --> 8 sides = x
4. sqrt(7^2 + (12/2)^2) = radius --> sqrt(49 + 36) --> sqrt85 * 2pi = circumference --> 57.9281062 = circumference --> 57.9
