1 answer:

3 0

\[(7.556\times 10^9)-(3.8\times 10^6) \]
\[=(7.556\times 10^3)10^6-(3.8)10^6\]
\[=(7556-3.8)10^6\]
\[=(7552.2)\times 10^6\]
\[=7.5522\times10^3\times10^6\]
\[=7.5522 \times10^9\]

$|\Omega|=(\text{the area of the triangle})=\dfrac{a^2\sqrt3}{4}=\dfrac{3^2\sqrt3}{4}=\dfrac{9\sqrt3}{4}\\|A|=(\text{the area of the sector})=\dfrac{\alpha\pi r^2}{360}=\dfrac{60\pi \cdot 1^2}{360}=\dfrac{\pi}{6}\\\\\\P(A)=\dfrac{\dfrac{\pi}{6}}{\dfrac{9\sqrt3}{4}}\\\\P(A)=\dfrac{\pi}{6}\cdot\dfrac{4}{9\sqrt3}\\\\P(A)=\dfrac{2\pi}{27\sqrt3}\\\\P(A)=\dfrac{2\pi\sqrt3}{27\cdot3}\\\\P(A)=\dfrac{2\pi\sqrt3}{81}\approx13.4\%$

What is the equation of the line that passes through the point (4,3) and has a slope of 1?

Mamont248 [21]

Answer (assuming it can be in point-slope form):

$y-3 = 1(x-4)$

Step-by-step explanation:

Use the point-slope formula $y-y_1 = m (x-x_1)$ to write the equation of the line. Substitute real values for $m$ , $x_1$ , and $y_1$ in the formula.

Since $m$ represents the slope, substitute 1 in its place. Since $x_1$ and $y_1$ represent the x and y values of a point the line intersects, substitute the x and y values of (4,3) in its place. Substitute 4 for $x_1$ and 3 for $y_1$ . This gives the following equation and answer in point-slope form:

$y-3 = 1(x-4)$
