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

Employees of a landscaping company built a retaining wall. They used brick to make the top 2/3 of the wall. The wall is 8and 1/2
IgorC [24]

Answer:

Height of the brick portion of the wall is 5.61 feet.

Step-by-step explanation:

Employees of the landscaping company used brick to build the top 2/3 of the wall. The total dimensions of the wall are 8 and 1/2 * 2 and 3/4 feet. So the height of the wall = 8 and 1/2 feet or in other words 8.75 feet.

Height of the brick portion of the wall = 2/3 * 8.5 = 0.66 * 8.5 = 5.61 feet

So the height of the brick portion of the wall is 5.61 feet.

Non brick portion of the wall is 8.5 - 5.61 = 2.89
