Answer:
The x-intercepts of f(-x) are -6 and -5
Step-by-step explanation:
we know that
The x-intercepts of f(x) are
x=5, x=6
That means
x-5=0
x-6=0
Substitute the variable x by -x
-x-5=0 ----> x=-5
-x-6=0 ----> x=-6
therefore
The x-intercepts of f(-x) are -6 and -5
Use the formula for the length of an arc:-
L = r C where r = radius and C = angle subtended in radians So here we have:_
18 = r * 130 * pi / 180
18 = 2.269 r
r = 7.93 cm to neraest hundredth
Order of Operations are PEMDAS. So, based on that, the answers would be:
1. 150. Do 20*5 first, as it's in parentheses, then multiply by 10.
2. 36. Same thing as #1 but different numbers.
3. 51. Do the stuff in parentheses first, then multiply because it gets priority over subtraction and then subtract.
4. 16. Do the multiplication in the parentheses first, then the subtraction, and then the division.
