Fine the exact distance between the line 6x-y=-3 and the point (6,2). Show your work. Explain your answer.

AVprozaik [17]

Answer:

$\sqrt{37}$ units

Step-by-step explanation:

If we draw a perpendicular from point (6,2) on the line 6x - y = - 3, then we have to find the length of the perpendicular.

We know the formula of length of perpendicular from a point $(x_{1}, y_{1} )$ to the straight line ax + by + c = 0 is given by

$\frac{|ax_{1} + by_{1} +c |}{\sqrt{a^{2}+b^{2}}}$

Therefore, in our case the perpendicular distance is

$\frac{|6(6)-2+3|}{\sqrt{6^{2} +(-1)^{2} } } = \frac{37}{\sqrt{37} } = \sqrt{37}$ units. (Answer)

An apple IPod sells for 299, which is marked up 40% of the selling price. What is the cost of the iPod ?

Shalnov [3]

Answer:

$\large \boxed{213.57}$

Step-by-step explanation:

Let x = cost of IPod

$\begin{array}{rcl}\text{Price} & = & \text{Cost + Markup}\\299 & = & x + 0.40x\\& = & x(1 + 0.40)\\& = & 1.40x\\x & = & \dfrac{299}{1.40}\\\\& = & \mathbf{213.57}\\\end{array}\\\text{The cost of the IPod is $\large \boxed{\mathbf{213.57}}$}$

Check:

$\begin{array}{rcl}299 & = & x + 0.40x\\299 & = & 213.57 + 0.40 \times 213.57\\299 & = & 213.57 + 85.43\\299 & = & 299.00\\\end{array}$
