Answer:

The ratio of the measure of the central angle to the entire circle measure=\dfrac{1}{2}

The area of the entire circle=36\pi$ units^2.

The area of the sector =18\pi $ units^2

Step-by-step explanation:

MNL is a diameter of the circle N

Radius, NL =6

  • The measure of central angle MNL = π radians
  • The measure of the entire circle = 2π radians.

The ratio of the measure of the central angle to the entire circle measure

=\dfrac{\pi}{2\pi}\\\\ =\dfrac{1}{2}

Area of a circle =\pi r^2

The area of the entire circle

= \pi \times 6^2 \\=36\pi$ units^2.

Therefore, the area of the sector

=\dfrac{1}{2}  \times 36\pi\\=18\pi $ units^2

Answer:

1)

\text{ Slope = -3}

2)

y+4=-\frac{7}{8}(x-7)

3)

y=-\frac{7}{8}x+\frac{17}{8}

Step-by-step explanation:

We want to write the equation of the line that passes through the points (7, -4) and (-1, 3) first in point-slope form and then in slope-intercept form.

1)

First and foremost, we will need to find the slope of the line. So, we can use the slope-formula:

m=\frac{y_2-y_1}{x_2-x_1}

Let (7, -4) be (x₁, y₁) and let (-1, 3) be (x₂, y₂). Substitute them into our slope formula. This yields:

m=\frac{3-(-4)}{-1-7}

Subtract. So, our slope is:

m=\frac{7}{-8}=-7/8

2)

Now, let's use the point-slope form:

y-y_1=m(x-x_1)

We will substitute -7/8 for our slope m. We will also use the point (7, -4) and this will be our (x₁, y₁). So, substituting these values yield:

y-(-4)=-\frac{7}{8}(x-7)

Simplify. So, our point-slope equation is:

y+4=-\frac{7}{8}(x-7)

3)

Finally, we want to convert this into slope-intercept form. So, let's solve for our y.

On the right, distribute:

y+4=-\frac{7}{8}x+\frac{49}{8}

Subtract 4 from both sides. Note that we can write 4 using a common denominator of 8, so 4 is 32/8. This yields:

y=-\frac{7}{8}x+\frac{49}{8}-\frac{32}{8}

Subtract. So, our slope-intercept equation is:

y=-\frac{7}{8}x+\frac{17}{8}

And we're done!
