Answer:

The correct answer is the last choice. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.

Step-by-step explanation:

In the first segment of the trip, the car goes from 0 to 2 hours and the line is moving up. Therefore, it traveled for 2 hours.

In the second segment, the line went straight horizontal for 1 hour. That means the distance didn't change, in other words, it didn't move.

In the last segment, it moved up again for 2 hours.

Which could be the entire interval over which the function f(x) is positive
aalyn [17]

(-\infty,-2) \cup(2,\infty)

<h2>Explanation:</h2>

Remember you need to write complete questions in order to find exact answers. In this way you haven't provided any function, so I'll choose a quadratic function given by:

f(x)=x^2-4x

So we need to find the entire interval at which this function positive. Put another way:

f(x)>0

By using graphing tool, we get the graph shown below. As you can see:

  • The function decreases from x=-\infty \ to \ x=0
  • The function increases from x=0 \ to \ x=\infty
  • The graph of the function is a parabola that opens up.

But what is really importan in this problem is that:

  • The function is positive over the interval (-\infty,-2) \cup(2,\infty)

At this interval the function is positive, that is, f(x)>0

Explain why the equation x+2=x+3 has no solution
Orlov [11]
It has no solution because x is always the same amount. So.. for example.
lets say x = 10.

then it would be 10 + 2 = 10 + 3.
12 doesnt = 13. :)

HELP PLEASE I NEED THIS DONE
Oduvanchick [21]

Answer:

138.3ft^3

Step-by-step explanation:

Volume for cylinders : V = pi*r^2*h

Volume for cones : V = pi*r^2*(h/3)

Since we know the radius (r) is 2 and the height is 10 and 3 for the cylinder and cone respectively, all we do is plug in.

Volume for cylinder is about 125.7ft^3

Volume for cone is about 12.6ft^3

Then just add them together for a total of 138.3ft^3

Helppppp plzzzz ASAP!!!!!!<br> Thank you!!!!!!
Zielflug [23.3K]

Answer:

option 4.

16 square units

Step-by-step explanation:

as we do not have the measures of the sides, but if the points of the vertices with Pythagoras we can calculate the sides.

P = (2 , 4)

S = (4 , 2)

we have to subtract the values ​​of p from s

PS = (4 - 2  , 2 - 4)

PS = (2 , -2)

by pitagoras h ^ 2 = c1 ^ 2 + c2 ^ 2

h: hypotenuse

c1: leg 1

c2: leg 2

PS^2 = 2^2 + -2^2

PS = √ 4 + 4

PS = √8

PS = 2√2

S = (4 , 2)

R = (8 , 6)

SR = (8-4  ,  6-2)

SR = (4 , 4)

by pitagoras h ^ 2 = c1 ^ 2 + c2 ^ 2

h: hypotenuse

c1: leg 1

c2: leg 2

SR^2 = 4^2 + 4^2

SR = √ (16 + 16)

SR = √32

SR = 4√2

having the values ​​of 2 of its sides we multiply them and obtain their area

PS * RS = Area

2√2 * 4√2 =

16
