Compare the functions below: Which function has the smallest minimum?
anzhelika [568]

Answer:

D. All three functions have the same minimum value

Step-by-step explanation:

f(x) = -3 sin (x-pi) +2

Sin has a minimum value of -1, but since it is multiplied by a negative, we want its maximum value

sin has a maximum of 1

f (min) = -3(1) +2 = -1

g(x) has a minimum at x =3  

g(minimum) = -1

h(x) = (x+7)^2 -1

        The smallest a squared value can be is zero

     = 0 -1

h(min) =-1

Enter the value for x that makes the equation true <br> 36(x-5)=9x-18
s2008m [1.1K]

Answer:

x = 6

Step-by-step explanation:

Solve for x:

36 (x - 5) = 9 x - 18

Expand out terms of the left hand side:

36 x - 180 = 9 x - 18

Subtract 9 x from both sides:

(36 x - 9 x) - 180 = (9 x - 9 x) - 18

36 x - 9 x = 27 x:

27 x - 180 = (9 x - 9 x) - 18

9 x - 9 x = 0:

27 x - 180 = -18

Add 180 to both sides:

27 x + (180 - 180) = 180 - 18

180 - 180 = 0:

27 x = 180 - 18

180 - 18 = 162:

27 x = 162

Divide both sides of 27 x = 162 by 27:

(27 x)/27 = 162/27

27/27 = 1:

x = 162/27

The gcd of 162 and 27 is 27, so 162/27 = (27×6)/(27×1) = 27/27×6 = 6:

Answer:  x = 6

A survey shows that 82% of youth most often use the internet at home. What fraction of the most often use the internet somewhere
My name is Ann [436]
82% as a fraction would be 82 over 100 when you simplify that you get 41 over 50. The missing percent is 18 because 18%+82%=100%. Next you would need to write 18 over 100 and then simplify that. You write it as 18 over 100 because it is 18 hundredths. If you wrote 18% as a decimal it would be 0.18 which is 18 hundredths which would be 18 over 100
