What is an equation of the line that passes through th (3,-1) and has a slope of 2?

dezoksy [38]

The given point to us is (3,-1) and the slope of the line is 2 . We can use the point slope form of the line as ,

$\sf\longrightarrow m ( x - x_1) = y - y_1$

Substitute the values ,

$\sf\longrightarrow 2( x - 3 ) = y - (-1)$

Simplify LHS and RHS ,

$\sf\longrightarrow 2x - 6 = y +1$

Put all terms on one side ,

$\sf\longrightarrow \boxed{\bf 2x - y -7=0}$

In a circle, area and circumference can be found using the formulas A=(pi)r^2 and C=2(pi)r, respectively, Write a formula for A

AURORKA [14]

Answer:

$A = \dfrac{C^2}{4\pi}$

Step-by-step explanation:

Given that

Area of a circle $A=\pi r^2$

Circumference of the circle $C = 2 \pi r$

Let us re-write the equation of area of circle:

$A=\pi r^2$

$A = \pi \times r \times r$

Multiplying and dividing with 2:

$A = \dfrac{2\pi r}{2} \times r\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C}{2} \times r\\\text{Multiplying and dividing by } 2\pi:\\\Rightarrow A = \dfrac{C}{2} \times \dfrac{2\pi r}{2\pi}\\\text{Putting }2\pi r = C:\\\Rightarrow A = \dfrac{C \times C}{4 \pi}\\\Rightarrow A = \dfrac{C^2}{4 \pi}$

Hence, A in terms of C can be represented as:

$A = \dfrac{C^2}{4\pi}$
