Allushta [10]

Answer:

Distance between Gas Station and House = 7.81 miles.

Step-by-step explanation:

Given: House location ( 4, 3 ) and Gas station location ( 10, 8)

          On graph 1 unit = 1 mile.

To find: Distance between Gas Station and House

We use the Distance formula to find the distance between two points (x_1,y_1)\:and\:(x_2,y_2)

Distance=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

From given points and formula,

Distance\:between\:house\:and\:gas\:station=\sqrt{(10-4)^2+(8-3)^2}

                                                             = \sqrt{(6)^2+(5)^2}

                                                             = \sqrt{36+25}

                                                             = \sqrt{61} units

Since, 1 unit = 1 mile

⇒ \sqrt{61}\:unit=\sqrt{61}miles=7.81 miles

Therefore, Distance between Gas Station and House = 7.81 miles.

1. The equation y=x^2-9x+20 models the roller coasters path over time. The variable y represents height (in feet) above or below
azamat

Answer:

1) the factored form is  y= ( x-5 ) ( x+4 )

2) the vertex is (4.5, -0.25)

3) the y intercept is when x equals 0 so it is at (0,20)

4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is  (0,20)

5)

a. it dips  between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)

b. it is taken at the vertex aka the lowest point so the height is -0.25
