\text{Area of the triangle = 6 unit}^2Explanation:

The triangle is right angled.

The formula for area of the triangle:

\begin{gathered} A\text{ = }\frac{1}{2}bh \\  \\ b\text{ = base} \\ h\text{ = height} \end{gathered}

base = 3

height = 4

substitute the values:

\begin{gathered} \text{Area of the triangle = }\frac{1}{2}\times3\times4\text{ = 12/2} \\ \text{Area of the triangle = 6 unit}^2 \end{gathered}

A water grist mill has a radius of 9ft and takes 8 seconds to make a complete rotation. a bucket starts at position (9,0). what
gavmur [86]

If the grist mill completes the rotation in 8 seconds. Then the final position of the bucket after 6 seconds is (0, 9).

<h3>What is coordinate geometry?</h3>

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

A water grist mill has a radius of 9ft and takes 8 seconds to make a complete rotation. a bucket starts at position (9,0).

Then the coordinates of the bucket's location after 6 seconds will be

The angle of rotation after 6 seconds will be

\rightarrow \dfrac{6}{8} \times 360\\\\\rightarrow 270^o

Then we have

x = 9 cos 270°

x = 0

and y will be

y = 9 sin 270°

y = -9

But the angle is in a clockwise direction, then

y = 9

More about the coordinate geometry link is given below.

A jogger runs around a circular track of radius 55 ft. Let (x,y) be her coordinates, where the origin is the center of the track
bagirrra123 [75]

Answer:

11.25 ft/sec

Step-by-step explanation:

Given that a jogger runs around a circular track of radius 55 ft.

. Let (x,y) be her coordinates, where the origin is the center of the track.

Then we know x,y satisfies the equation of the circle as

x^2+y^2 = 55^2

Let us differentiate this implicit function with respect to t

2x \frac{dx}{dt} +2y \frac{dy}{dt} =0

At this point, dx/dt 15 and x=33. y =44

Substitute to have

2(33)(15) +2(44) \frac{dy}{dt}\\=0\\\frac{dy}{dt}=11.25

dy/dt = 11.25 ft /s

So the three numbers can be turned into fractions.

1/5, 1/4, and 4/20.

fractions can be turned into decimals by dividing the denominator into the numerator.

now we have 0.2 , 0.25 , and 0.2

greatest to least, the numbers are 0.25 , 0.2 , and 0.2

(both 0.2s are equal, so order of those doesn't matter)
