Sam is making a case for his calculator. It is a rectangular prism that will be 5.5 inches long by 2 inch wide by 5 inches high.
White raven [17]

Answer:

97in³

Step-by-step explanation:

L = 5.5, W = 2, H = 5

2(h × W) + 2(h × L) + 2(W × L)

= 2(5*2) + 2(5*5.5) + 2(2*5.5)

= 2(10) + 2(27.5) + 2(11)

= 20 + 55 + 22

= 97in³

If f(x) = -x-2, what is f¹(x)?
astra-53 [7]

Answer:

  1. f¯¹(x) =9x+18, for the pictorial(image) question
  2. what is the send question is it asking derivative or inverse
  3. If it is inverse f¯¹(x)=-x-2 as it is
  4. Or if it is derivative f'(x)=-1

Step-by-step explanation:

<h2>For the image question f(x)=1/9x-2,f¯¹(x)=?</h2>
  • f(x)=1/9x-2............given
  • y=1/9x-2................swapping f(x) by y to Easily write
  • x=1/9y-2................interchanging x and y
  • 1/9y-2=x................changeling side of equation
  • 9(1/9y-2)=(x)9.......multiplying both sides by 9 to override the fraction on the right side
  • y-18=9x
  • y=9x-18.................Return to where it were
  • <em><u>f¯¹(x)=9x+18</u></em>..........swap back f¯¹(x) in the y

<h2>For the question f(x)=-x-2,f¯¹(x)=?</h2>
  • following the ☝️ arrangement
  • y=-x-2
  • x=-y-2
  • -y-2=x
  • -y=x+2
  • y=-x-2
  • f¯¹(x)=-x-2
