Answer:

\huge  \boxed{\displaystyle 7}

Step-by-step explanation:

we would like to simplify the following expression:

\displaystyle (2 + 2) + (4 - 1)

in order to do we can consider the order of PEMDAS which is the abbreviation of Parentheses, Exponent, Multiplication,or Division, Addition or substraction

since Parentheses come first we'll simplify parentheses:

\displaystyle 4 + 3

simplify addition:

\displaystyle 7

and we are done!

The water from a fire hose follows a path described by y equals 2.0 plus 0.9 x minus 0.10 x squared ​(units are in​ meters). If
Alecsey [184]

Answer:

The resultant velocity is 12.21 m/s.

Step-by-step explanation:

We are given that the water from a fire hose follows a path described by y equals 2.0 plus 0.9 x minus 0.10 x squared ​(units are in​ meters).

Also, v Subscript x is constant at 10.0 ​m/s.

The water from a fire hose follows a path described by the following equation below;

y=2.0 + 0.9x-0.10x^{2}

The velocity of the x component is constant at =  v_x=10.0 \text{ m/s}

and the point at which resultant velocity has to be calculated is (9.0,2.0).

Let the velocity of x and y component be represented as;

v_x=\frac{dx}{dt} \text{   and    }   v_y=\frac{dy}{dt}

Now, differentiating the above equation with respect to t, we get;

y=2.0 + 0.9x-0.10x^{2}

\frac{dy}{dt} =0 + 0.9\frac{dx}{dt} -(0.10\times 2)\frac{dx}{dt}

\frac{dy}{dt} = 0.9\frac{dx}{dt} -0.2\frac{dx}{dt}

v_y = 0.9v_x -0.2v_x

v_y = 0.7v_x

Now, putting v_x=10.0 \text{ m/s} in the above equation;

v_y = 0.7 \times 10.0 = 7 m/s

Now, the resultant velocity is given by = v=\sqrt{v_x^{2}+v_y^{2}  }

                            v=\sqrt{10^{2}+7^{2}  }

                               = \sqrt{149} = 12.21 m/s

Select all the correct equations.
Naya [18.7K]

Answer:

You did not post the options, but i will try to answer this in a general way.

Because we have two solutions, i know that we are talking about quadratic equations, of the form of:

0 = a*x^2 + b*x + c.

There are two easy ways to see if the solutions of this equation are real or not.

1) look at the graph, if the graph touches the x-axis, then we have real solutions (if the graph does not touch the x-axis, we have complex solutions).

2) look at the determinant.

The determinant of a quadratic equation is:

D = b^2 - 4*a*c.

if D > 0, we have two real solutions.

if D = 0, we have one real solution (or two real solutions that are equal)

if D < 0, we have two complex solutions.
