Answer:

A = 0.25 π m²

Step-by-step explanation:

Area = $\pi r^2$

Where r = 0.5 m

A = (0.5)^2 × π

A = 0.25 π m²

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 ,

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

Answer:

not a right triangle

Step-by-step explanation:

We can use the Pythagorean theorem to see if it is a right triangle

a^2 + b^2 = c^2

15^2 + 12^2 = 21^2

225 + 144 = 441

369 = 441

This is not true so it is not a right triangle

Write an equation of a line that is parallel to the line whose equation is 3y=x+6 and that passes through the point (-3,4).

Monica [59]

The standard form of this equation is

$y=\frac{1}{3}x+2$

The slope of two parallel lines i the same, so the slope of the line we're looking for is also $\frac{1}{3}$

Since the line passes through $(-3,4)$ , the equation is:

$(y-4)=\frac{1}{3}(x+3)$

$\boxed{y=\frac{1}{3}x+5}$

What is 3 1/2 - 2 5/7 and show the work

Hunter-Best [27]

$3 \frac{1}{2} -2 \frac{5}{7} = \frac{(3\cdot2)+1}{2} - \frac{(2\cdot7)+5}{7} = \frac{7}{2} - \frac{19}{7} \\\\= \frac{7\times 7}{2\times 7} - \frac{19\times 2}{7\times 2} = \frac{49}{14} - \frac{38}{14} \\\\= \frac{49-38}{14} =\boxed{\bf{\frac{11}{14}}}$
