Answer:
62.8 If rounded to the nearest hundredth it is 62.80
Step-by-step explanation:
1. Formula for circumference of a cirlcle is 2 (pi) r where for this problem,
2 =2,
pi= 3.14 and
r= 10 (1/2 of the diameter =radius)
2. 2 x 3.14 x 10
multiply all 3 numbers above, you get 62.8
3. Depending on your teacher or the test,
62.8 is your answer, if it HAS to be to the nearest hunderedth, and it's on a specific program, it might want you to enter the "0" at the end 62.80
2⁵ = 2*2*2*2*2
= 32
f(x) = 3x+2
g(x) = 2x - 2
To find (f-g)(x)
(f-g)(x) = f(x) - g(x)
Substitute f(x) to 3x+2 and g(x) to 2x -2
(f-g)(x) = (3x+2) - (2x-2)
Open the brackets
(f-g)(x) = 3x+2-2x+2
Rearrange
(f-g)(x) = 3x-2x+2+2
(f-g)(x) = x + 4
Answer is option A = x + 4
The (-3x-9)=27 and (-5x-2)=10
x=10
