A factory produces widgets whose length must be within 1.5 mm of an ideal length of 47 mm. A factory supervisor wants to mark ru
Nat2105 [25]

Using absolute value, it is found that:

  • The situation is described by the following equation: |l - 47| = 1.5
  • The markings should be between 45.5mm and 48.5mm.

---------------------------

The definition of the <em>absolute value function</em> is as follows:

|x| = x, x \geq 0

|x| = -x, x < 0

----------------------------

The length should be set to 47mm with an allowance of 1.5mm, which means that <u>the absolute value of the difference between the length and 47 should be 1.5</u>, thus:

|l - 47| = 1.5

----------------------------

The solutions are:

l - 47 = -1.5 \rightarrow l = 45.5

l - 47 = 1.5 \rightarrow l = 48.5

The markings should be between 45.5mm and 48.5mm.

4x-3y=1<br> 5x+4y=9<br> What are the resulting equations?
Alex

Answer:

x = 1; y = 1

Step-by-step explanation:

First thing we will do is work with the first equation:

4x - 3y = 1

4x = 1+3y

x = \frac{3}{4} y~+~\frac{1}{4}

Now that we have a value for x, we insert that into the second equation, like so:

5(\frac{3}{4}y~+~\frac{1}{4}) + 4y = 9

\frac{15}{4}y~+~\frac{5}{4} + 4y = 9

\frac{15}{4}y~+~4y~+~\frac{5}{4} = 9

\frac{15}{4}y~+~\frac{16}{4} y~+~\frac{5}{4}

\frac{31}{4}y~+~\frac{5}{4} =9

31y + 5 = 9 * 4

31y + 5 = 36

31y = 36-5

31y = 31

y = \frac{31}{31}

y = 1

Now, we solve for x:

4x - 3(1) = 1

4x - 3 = 1

4x = 1 + 3

4x = 4

x = \frac{4}{4}

x=1

A hunter walks 400m Up a hill which slopes at an angle of 20 to the horizontal. Calculate,correct to the nearest metre, the: a.
AysviL [449]

let y be the horizontal distance and x the vertical

y/400 = cos 20

y=400 cos20

y=376m

x/400 =sin20

x=400sin20

x=137m
