9) pi/3 = 180 /3 = 60⁰

the other angle = 90-60=30⁰

10) 2pi/9 = 360/9 = 40⁰

the other angle = 90+40=130⁰

11) arc length = 2pi * r * (θ/360)

= 2pi * 16 * (270/360)

= 75.4 km

12)arc length = 2pi * r * (θ/360)

3 * 180/4 = 135⁰

135/360 =0.375

2pi * 6 * 0.375 =14.13 in

13) arc length = 2pi * r * (θ/360)

= 9 *2pi *(255/360) =40.05 mi

14)arc length = 2pi * r * (θ/360)

=23.56 mi

Answer:

For this expression I guessed I would use subtraction because when you subtract Kimiko's miles to Celeste's miles you could see how much faster Kimiko was than Celeste.

The image of a parabolic lens is projected onto a graph. The image crosses the x-axis at –2 and 3. The point (–1, 2) is also on

Ierofanga [76]

Answer:

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

Step-by-step explanation:

Given

$x_1 = -2$

$x_2 = 3$

$(x,y) = (-1,2)$ --- a point on the parabola

Required

The equation

First, calculate the equation from the zeros

$y =k(x - x_1)(x - x_2)$

Substitute $x_1 = -2$ and $x_2 = 3$

$y =k(x - -2)(x - 3)$

$y =k(x +2)(x - 3)$

To solve for k, we substitute $(x,y) = (-1,2)$

$2 = k(-1+2)(-1-3)$

$2 = k(1)(-4)$

$2 = -4k$

Divide by -4

$k=\frac{2}{-4}$

$k=-\frac{1}{2}$

So, the equation is:

$y =k(x +2)(x - 3)$

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