X / 10pi = 360 /((pi)(r^2))

To isolate x, multiply both sides by 10pi

x = 360 /((pi)(r^2)) (10pi) = 3600/r^2 = 3600 / 20^2 = 9 degrees

To isolate x, multiply both sides by 10pi

x = 360 /((pi)(r^2)) (10pi) = 3600/r^2 = 3600 / 20^2 = 9 degrees

Angles 1, 3, 5, 7, 9 and 11 are corresponding while angles 2, 4, 6, 8, 10 and 12 are corresponding

angles 8 and 7 are supplementary

since 4 and 8 are corresponding, angle 4 is 132° so angle 8 would also be 132°

180-132=48°

angle 7 would be 48°

angles 8 and 7 are supplementary

40 people prefer vanilla (13 of day 1,12 of day 2 and 15 of day 3)

That means, out of 150 : 40 prefer vanilla

out of 2300 : prefer vanilla

≈ 613

Space in the box = volume

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

box 2 volume = 15 x 20 x 14 = 4200

how much space is left = box 2 - box 1 = 1200 inches

volume = length x width x height

box 1 volume = 15 x 20 x 10 = 3000

box 2 volume = 15 x 20 x 14 = 4200

how much space is left = box 2 - box 1 = 1200 inches

Since we are given 2 sides and 2 angles, we can use the Side Angle Side (SAS) method. The area of a triangle is given by the formula:

Area = absinC/2; where a and b are adjacent sides and C is the angle between a and b.

Area = 5*8*sin31°/2 = 10.3 square units.

Area = absinC/2; where a and b are adjacent sides and C is the angle between a and b.

**Answer:**

Height of the dam is 45.45 meters.

**Step-by-step explanation:**

From the attached figure, AB is the height of dam NM is Scarlett's height. We have to find the height of the dam. NM = CB = 1.65 m

Using trigonometric equations as:

**AC = 43.8 m**

**So, the height of the dam is AC + CB = 43.8 m + 1.65 m = 45.45 m**

**Hence, the height of the dam is 45.45 meter.**

Amplitude: the height of the graph from the peak to the axis. On the unit circle it would be the radius (max and min values) at 0, pi/2, 2pi

Period: the length of one full cycle of the cos graph. On the unit circle it is the circumference. The distance around a circle with radius = 1.

Domain: the x value or the values on the horizontal axis. On the unit circle these would be the radian measures around the unit circle such as pi/6, pi/4,

pi/3, pi/2.

Range: the y value or the values on the vertical axis. On the unit circle it would be the cosine value for each radian measure. Such as cos pi/4 = (sqrt2)/2, cos pi/3= 1/2.

X-intercepts: the points where the graph crosses the horizontal axis. On the unit circle these are the cosine values when theta is at the vertical points of the unit circle, pi/2 and 3pi/2.

QUESTION POSTED AT 28/03/2020 - 12:19 PM

**Answer:**

One point could be (1,1)

**Step-by-step explanation:**

1. The equation of the circle is

h and k are the (x,y) coordinates of the center of the circle respectively. In this sense, h=6 and k=1, and r is the radius of the circle which is 5. Replacing we get

2. The x-coordiante of the center of the circle is at x=6. The radius is 5, therefore, the left end of the circle is at x=1 and the right end is at x=11. This means that the circle can take x-coordiantes from 1 to 11, and for each we will have a Y-coordinate.

3. To get the Y-coordinate we isolate Y from the circle equation.

4. From the last equation, we can repalce x by any number between 1 and 11, and we will get the respective Y-coordinate, for example:

If we take x=1, replacing we get:

So, one point could be (1,1)

5. If you want to get another point, you could replace X by 2,3,4,5,6,7,8,9,10 and 11 in the previous equation, and for each one you will get a new Y-coordinate.

The shape of the mirror can be modeled by

**We know that the standard form for the equation of parabola is , where focus = (h+p,k)**

Rewrite the given equation in the standard form , we get

Therefore, focus of the flashlight=(-2+3,-5)=(1,-5)
