A car travels along a straight road for 30 seconds starting at time t = 0. Its acceleration in ft/sec2 is given by the linear gr
I am Lyosha [343]
From an acceleration-time graph, you can work out the area under the graph to find the velocity. There are two triangles on the graph as shown below. The total area of the triangles are

\frac{(10)(10)}{2}+ \frac{(20)(20)}{2}=250 ft/sec^{2}

Hence, the distance is 250×30=7500 ft

Andrei [34K]

Answer:

Step-by-step explanation:A.

B.

Slope =

Step-by-step explanation:

We are given the equation of the line as .

A. The co-ordinate is given by

Substituting the value , we get,

implies  implies   i.e. 3x = -1 i.e.

Thus, the co-ordinate is .

B. The co-ordinate is given by

Substituting the value , we get,

implies  implies   i.e. 9y = 0 i.e. y= 0

Thus, the co-ordinate is .

Since, the slope of a line is given by .

We get,

Slope = .

i.e. Slope = .

i.e. Slope = .

Hence, the slope of the line is .

Find the coordinates of the circumcenter for triangle DEF with coordinates D(1,3) E(8,3) and F(1,-5) show your work
nikklg [1K]

One leg is horizontal, on the line y=3. Another leg is vertical, on the line x=1. The point where these intersect, D(1, 3) is the vertex of a right angle. Any right triangle inscribed in a circle has its hypotenuse as the diameter of the circle.

Since the triangle is a right triangle, the circumcenter is the midpoint of the hypotenuse: ((8, 3) + (1, -5))/2 = (4.5, -1).
