Answer:

Sue biked 3,500,000 centimetres.

Step-by-step explanation:

First, multiply 5 km by 7 (days). 5 × 7 = 35 km

Convert the kilometres to centimetres.

There are 100,000 cm in a kilometer, so multiply:

35 × 100,000 = 3,500,000 cm.

Answer:

The coordinates of B are: (a, b)=(-2, -6)

Step-by-step explanation:

Let (a, b) be the coordinates of the point 'B'.

As

The midpoint of AB is M(-4, 0)

The coordinates of A are (-6, 6)

The midpoint (x,y) of line joining points (x₁, x₂) and (y₁, y₂)

x=\frac{x_1+x_2}{2},\:y=\frac{y_1+y_2}{2}

-4 = (-6+a)/2  and  0 = (6+b)/2

-8=-6+a          

-8+6=a                  

a=-2

0=(6+b)/2

0=6+b

b=-6

Therefore, the coordinates of B are: (a, b)=(-2, -6)

What is the positive solution to the equation 0 = –x2 + 2x + 1? Quadratic formula: x = –2 + 2 – 1 + –1 +
Georgia [21]

The standard form of a quadratic equation is :

ax² + bx + c = 0

And the quadratic formula is:

x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} .

So, first step is to compare the given equation with the above equation to get the value of a, b and c.

So, a = -1, b = 2 and c = 1.

Next step is to plug in these values in the above formula. Therefore,

x=\frac{-2\pm\sqrt{(2)^2-4*(-1)*(1)}}{2*(-1)}

=\frac{-2\pm\sqrt{4+4}}{-2}

=\frac{-2\pm\sqrt{8}}{-2}

=\frac{-2\pm\sqrt{4*2}}{-2}

=\frac{-2\pm\sqrt{4}*\sqrt{2}}{-2}

=\frac{-2\pm2*\sqrt{2}}{-2}

=-\frac{-2}{-2} \pm\frac{2\sqrt{2}}{-2}

So, x =1 \pm\sqrt{2} .

Find the slope of the line that passes through the pair of points.
Korolek [52]

Answer:

-.033557047

Step-by-step explanation:

Slope = (y2-y1)/ (x2-x1)

    = (4.2 - 5.6)/(.86- 40.86)

 = -1.4/ (.86 + 40.86)

= -1.4/41.72
