Can someone help me find the domain and range of this graph?​
arlik [135]

Answer:

Domain: (-5, 6]

Range: [-3, 6]

Step-by-step explanation:

Domain is all x-values that can be inputted into function f(x).

Range is all the y-values outputted by function f(x) when we plug in <em>x</em>.

We see that our x-values span from -5 to 6. Since -5 is a open dot, we cannot input -5. Therefore, we have:

Domain: (-5, 6]

Parenthesis on -5 shows that it is not included and bracket on 6 shows it is included.

We see that our y-values span from -3 to 6. Since both points are closed dots, we can include both. Therefore, we have:

Range: [-3, 6]

Brackets on both numbers signify that both values are included in the graph.

I need help on this histogram​
spayn [35]

each number in the box goes in one of the categories on the bottom of the historgram. so if the number is 7, it would go in the first column because it is between 1 and 10, and would go up one number according to the numbers on the left side. in this problem there are 2 numbers between 1 and 10 so the bar graph goes up to the 2 line.

Bank robber holds up a bank and speeds off at 71 mph. Police start chasing him 10 minutes later going 78 mph. How long will it t
alexira [117]

Answer:

It takes 1.68 hours to catch up to them.

Step-by-step explanation:

The speed of robber = 71 mph

The  speed of police =  78 mph

The police  start 10 minutes  later

by that time robber would have travelled

distance  = \frac{speed}{time}

10 minutes  =0.166667 hours

then the distance  =  11.8 mph

Let them meet at distance x from the bank.

time taken by police to reach x , time =\frac{ x}{78}----------------------(1)

time taken by robber in the same time = \frac{x-11.8}{71}---------------(2)

Equating (1) and (2)

\frac{x}{78} =\frac{ x-11.8}{71}

71 x = 78(x - 11.8)

71x =78x - 920.4

920.4 = 78x - 71x

920.4 = 7x

x = 131.48

The distance where they catch up with the robber from the bank is 131.48 miles

speed of police = 78 mph

distance =  131.48  miles

time they catch up = \frac{131.48}{78}

= 1.68 hours
