iVinArrow [24]

The function is updated by calculating the composite function h(f(c)), where f = 1.8c + 32

<h3>How to update the function?</h3>

The function is given as h(c)

Where

  • c represents the temperature in Celsius
  • h(c) represents the number of heat-stroke deaths per thousand people

When a temperature in Celsius is converted to Fahrenheit, the conversion equation is:

F = 1.8C + 32

This means that we update the function by calculating the composite function h(f(c)), where f = 1.8c + 32

<h3>How the graph would be transformed?</h3>

In (a), we have:

h(f(c)) and f = 1.8c + 32

Substitute f = 1.8c + 32 in h(f(c))

h(1.8c + 32)

The above means that:

  • The graph would be vertically stretched by a factor of 1.8
  • Then the graph would be shifted up by 32 units

the length of a rectangular building is 6 feet less than 3 times t he width. The perimeter is 120 feet. Find the width and the l
garri49 [273]
Call the width x.  Note that the length is 3x-6.  We know that double the width plus double the length is 120, so we write an equation:

2(x)+2(3x-6)=120
2x+6x-12=120
8x-12=120
8x=132
x=16.5
If x is 16.5, the width is 16.5, and the length is 3 \cdot 16.5 - 6 = 43.5.

Lin ran 2 3/4 miles in 2/5 of an hour. Noah ran 8 2/3 miles in 4/3 of an hour.
sveticcg [70]
(The second one)
Noah ran 8.67 miles in 1 hour and 20 minutes
If we convert the fraction to a decimal (for the miles part) we get 8.67 or 8 2/3 miles.

If 1/3 of an hour is 20 minutes, and an hour is 60 minutes, we add 20 4 times, which gets us to 80, which is 20 past an hour.

Given the equation 4x − 26 = 2x − 4, which order of operations completely solves for x?
scoray [572]
4x - 26 = 2x - 4....subtract 2x from both sides
4x - 2x - 26 = -4...add 26 to both sides
4x - 2x = -4 + 26...combine terms
2x = 22...divide both sides by 2
x = 22/2 = 11

OR
4x - 26 = 2x - 4.....subtract 4x from both sides
-26 = 2x - 4x - 4....add 4 to both sides
-26 + 4 = 2x - 4x...combine terms
-22 = -2x....divide both sides by -2
-22/-2 = x
11 = x
