Answer:

x>5

Step-by-step explanation:

3x>x^2-10

0>x^2-3x-10

(x-5)(x+2)

x>5 and x>-2

x>5 is the only positive solution

Two children, Ferdinand and Isabella, are playing with a water hose on a sunny summer day. Isabella is holding the hose in her h
wolverine [178]

Answer:

 f = 0.84 or 84%

Step-by-step explanation:

Given:

- Original constant velocity of water v_o = 3.5 m/s

- The original diameter of the hose opening d_o = 1.5 cm

- The total vertical distance y(f) = 1.0 m

- The total range x(f) = 10.0 m

Find:

What fraction of the original area does Isabella has to reduce or pinch so the water can cover the entire range.

Solution:

- We will assume the flow of water as a stream of particles that follow a path of single point.

- Using second kinematic equation in the vertical direction and compute the time it takes the water to reach the ground:

                                  y(t) = y(0) + v_y*t + 0.5*gt^2

Where, y(0) = v_y = 0,

                                  1.0 = 0.5*g*t^2

                                  t = sqrt ( 2*1 / 9.81 )

                                  t = 0.4515 s

- Now we will use the second equation of motion for the x- direction motion:

                                 x(t) = x(0) + v_x*t

Where, x(0) = 0,

                                 10 = 0 + v_x*(0.4515)

                                 v_x = 10 / 0.4515 = 22.1 m/s

- We have calculated the minimum velocity required to reach the range from isabella and ferdinand.

- We will use the continuity equation to compute the area required for the velocity calculated v_x = 22.1 m/s:

                                A_f*v_x = A_o*v_o

                                A_f = A_o*v_o / v_x

                                A_f = pi*0.015^2*3.5 / 4*22.1

                                A_f = 1.12 * 10^-4 m^2

- The fraction f of the reduction of area is:

                                f = (A_o - A_f) / A_o

                                f = (7.068*10^-8 - 1.12*10^-4) / (7.068*10^-8)

                               f = 0.84 or 84%

V=pir^2h solve this equation for h
Nady [450]
Since we are solving for h, the equation:

V = πr²h

...divides πr² to the other side. Thus, it becomes....

\frac{V}{ \pi r^2} = h

Which can be rewritten as....

h = \frac{V}{ \pi r^2}

Can someone help me with this work please
tangare [24]

Answer:

-See below

Step-by.step explanation:

In the first column, on the left of the vertical line, you place the first digit of the number , then on the second row on you place the second digit.

So on the second row you have the entries:

1 | 2 2 4 representing  12, 12 and 14.

On the first  row the 2 0ne digit numbers 3 and 8 are represented by

0 | 3 8.

Similarly the last 2 rows are:

2 |  0 1 3 6

3 |  4
