The inverse of the function f(x) = 1/2x + 10 is shown.

1 answer:

4 0

We have to find the inverse of the function:
f ( x ) = 1/2 x + 10
y = 1/2 x + 10
- 1/2 x = - y + 10 / * ( - 1 )
1/2 x = y - 10 / * 2
x = 2 y - 20
f^(-1) ( x )= 2 x - 20
h ( x ) = 2 x - 20
Answer:
The missing value is 20.

A metal conduit will be used as a pathway for wiring through a concrete block. The conduit is a 5 foot long rod with an outer di

kolbaska11 [484]

Answer: 586.59 cubic centimeters .

Step-by-step explanation:

As per given . we have

Inner diameter = 1.8 inches

⇒Inner radius :r = 0.9 in. (radius is half of diameter)

= 0.9 x (2.54) = 2.286 cm [∵ 1 in . = 2.54 cm]

Outer diameter = 2 inches

⇒Outer radius : R = 1 inch = 2.54 cm

Height : h = 5 feet = 5 x(30.48) = 152.4 cm [∵ 1 foot = 30.48 cm]

The formula to find the volume of a hollow cylinder :

$V=\pi(R^2-r^2)h$ , where R= outer radius , r= inner radius and h= height.

Now , the volume of metal in the conduit :

$V=(3.14)(( 2.54)^2-(2.286)^2)(152.4)$

$V=(3.14)(6.4516-5.225796)(152.4)$

$V=(3.14)(1.225804)(152.4)$

$V=586.591342944\approx586.59\ cm^3$

Hence, the volume of metal in the conduit is 586.59 cubic centimeters .

M−2 over 4 =5 over 20

Ne4ueva [31]

m=3
Plug it in and it should work
3-2 =1 over 4 which is the same as 5 over 20 because both as a percentage equal 25% or 1/4 or 0.25 if you put it in a calculator as calculators provide decimal answers
