what is the equation of a line that passes through the point (6,1) and is perpendicular to the line whose equation is y=2x-6?
alexandr402 [8]

Answer:

y = -(1/2)x + 4

Step-by-step explanation:

Use the standard form on an equation:  y = mx + b

A line that is perpendicular has a slope that is the opposite reciprocal of the other line.  We also have a point (x, y) that is on the line, so our equation begins as..

1 = -(1/2)(6) + b           We must solve for b (  -1/2 is the opposite reciprocal of 2)

1 = -3 + b

4 = b  

so our equation is

y = -(1/2)x + 4

Need help with linear approximation
Dmitrij [34]
Consider a function f(x), the linear approximation L(x) of f(x) is given by

L(x)=f(a)+(x-a)f'(a)

Given the quantity: \frac{1}{203}

We approximate the quantity using the function f(x)= \frac{1}{x}, where x = 203.

We choose a = 200, thus the linear approximation is given as follows:

L(203)=f(200)+(203-200)f'(200) \\  \\ = \frac{1}{200} - \frac{3}{200^2} = \frac{200-3}{200^2} = \frac{197}{40,000} =0.004925

Which of the following is the correct expansion of (3x-y)2
Studentka2010 [4]

\bold{[ \ Answer \ ]}

\boxed{\bold{9x^{2} \ - \ 6xy \ + y^{2} }}

\bold{[ \ Explanation \ ]}

  • \bold{Find \ Expansion: \ (3x \ - \ y^{2} )}

\bold{----------------------}

  • \bold{[Apply \ Perfect \ Square \ Formula\ (\left(a-b\right)^2=a^2-2ab+b^2)] \ a \ = \ 3x, \ b \ = \ y}

\bold{\left(3x\right)^2-2\cdot \:3xy+y^2}

  • \bold{[Simplify \ \left(3x\right)^2-2\cdot \:3xy+y^2] \ 9x^2-6xy+y^2}

= \bold{9x^2-6xy+y^2}

\boxed{\bold{[] \ Eclipsed \ []}}
