Answer:

Diameter = 2 m

Radius = 1 m

Area = 3.14 m²

Circumference = 6.28 m

Step-by-step explanation:

✔️Area of the circular rug is already given as 3.14 m²

✔️find radius (r):

Area = πr²

Thus,

Take π as 3.14

3.14*r² = 3.14

Divide both sides by 3.14

r² = 3.14/3.14

r² = 1

find the square root of both sides

r = √1

radius (r) = 1 m

✔️Diameter = 2*r = 2*1 = 2 m

✔️ Circumference = 2πr

r = 1 m

π = 3.14

Thus,

Circumference = 2*3.14*1 = 6.28 m

Tommy and Arnold are playing with water balloons. Arnold is standing by a bush that is 20 feet from where Tommy is standing. Tom
erik [133]

Answer:

The equation that describes the path of the water balloon is:

y =-\frac{1}{10}\cdot (x-10)^{2}+15

Step-by-step explanation:

The motion of the water balloon is represented by quadratic functions. Tommy launches a water balloon from A(x,y) = (0\,ft, 5\,ft) and hits Arnold at B(x,y) = (20\,ft, 5\,ft). Given the property of symmetry of quadratic function, water ballon reaches its maximum at C(x,y) = (10\,ft,15\,ft), which corresponds to the vertex of the standard equation of the parabola, whose form is:

y = a\cdot (x-h)^{2}+k (Eq. 1)

Where:

a - Vertex parameter, measured in \frac{1}{ft}.

h, k - Horizontal and vertical components of the vertex, measured in feet.

x, y - Horizontal and vertical location of the ball, measured in feet.

If we know that x = 0\,ft, y = 5\,ft, h = 10\,ft and k = 15\,ft, the vertex parameter is:

5\,ft = a\cdot (0\,ft-10\,ft)^{2}+15\,ft

a = \frac{5\,ft-15\,ft}{(0\,ft-10\,ft)^{2}}

a = - \frac{1}{10}\,\frac{1}{ft}

The equation that describes the path of the water balloon is:

y =-\frac{1}{10}\cdot (x-10)^{2}+15

The graph shows the function f(x).
elena-14-01-66 [18.8K]

Answer:

a) -3.5

Step-by-step explanation:

The average rate of change of a function f(x) from x=a to x=b is given by:

\frac{f(b) - f(a)}{b - a}We want to find the average rate of change of change of the given function from x=1 to x=4.

From the graph,

f(4) \approx \:  - 3.8

f(1) = 3

The average rate of change is:

\frac{ - 3.8 - 3}{4 - 1}  =  \frac{ - 6.8}{2} =  - 3.4

a) is closest
