Inez and Joel work at a store that sells
faltersainse [42]

Answer:

2 hrs and 32 mins

Step-by-step explanation:

Step 1. Because Inez worked more we are going to start by subtracting the the minutes. 23-51= -28.

Step 2. Now we move on to the hours. 7-4= 3. Know we know that the hour time is going to be three. But wait!

Step 3. Because we can't have negative numbers, we need to subtract some more. 60-28= 32. Now I know that my minutes will be 32.

Step 4. But because we used a negative number we have to subtract another hour from our time.

Answer: 2 hrs and 32 mins

Hope this helps!

It is known that the straight line l is tangent to the circle x^2+y^2=4 at a point on the x-axis, and intersects with the straig
Talja [164]

Step-by-step explanation:

The general equation of a circle is

                                         (x \ - \ h)^2 \ + \ (y \ - \ k)^2 \ = \ r^{2},

where <em>h</em> and <em>k</em> forms the coordinates of the centre of the circle.

When the circle has a centre at the origin, the equation reduces into

                        .                            x^2 \ + \ y^2 \ = r^2.

Now, we are interested in solving for the <em>x</em>-intercepts (the <em>x</em>-coordinates when the circle intersects the <em>x</em>-axis), of the circle

                                                      x^2 \ + \ y^2 \ = \ 4 .

Thus,

                                                     x^2 \ + \ (0)^2 \ = \ 4 \\ \\ \\ \-\hspace{1.3cm} x^{2} \ = \ 4 \\ \\ \\ \-\hspace{1.4cm} x \ = \ \pm \ 2.

Geometrically speaking, the tangent to the circle at the point defined by one of the <em>x</em>-intercepts of the circle is actually a vertical line, more specifically the lines x \ = \ \pm \ 2.

First and foremost, for the vertical line x \ = \ 2, it intersects the straight line y \ = \ \displaystyle\frac{1}{2}x  , giving the y-coordinate for point P,

                                                    y \ = \ \displaystyle\frac{1}{2}(2) \\ \\ \\ y \ = \ 1.

Hence, the coordinates of point P are (1, \ 1).

However, since there are no boundaries given in the question and a circle is symmetrical about its centre, thus, point P also exists when the vertical line x \ = \ -2 and interdects the straight line y \ = \ \displaystyle\frac{1}{2}x.

                                                      y \ = \ \displaystyle\frac{1}{2}(-2) \\ \\ \\ y \ = \ -1.

Therefore, the coordinates of point P are also (1, \ -1).
