A track runner ran for 15 minutes, walked for 15 minutes, ran for another 20 minutes, and then stretched in place for 10 minutes

.Which graph describes the relationship between runner's total distance and time?

Note that:

When the track runner runs, he is expected to cover more distance than when walks

When he stretches his body, he is not expected to cover any distance because there is no motion when the body is stretched in place.

By carefully observing the graphs shown, the correct graph will be plotted in the format below:

Long distance for the first 15 minutes

Short distance for the second 15 minutes

Longer distance for the next 20 minutes

No distance covered in the last 10 minutes

Therefore, the only graph that describes the relationship between the runner's total distance and time is option B

Question 2 of 4
Alexxandr [17]

Answer:

The time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.

Step-by-step explanation:

The function for the height of the bottle rocket (in feet), <em>t</em> seconds after  it is launched is:

h(t)=1157-16\ t

Compute the value of <em>t</em> as follows:

h(t)=1157-16\ t

200=1157-16t

 16t=1157-200\\16t=957\\

     t=59.8125\\t\approx60

Thus, the time it took for the bottle rocket to reach a height of 200 feet is 60 seconds.

PLEASE HELP!!!<br>Simplify the expression and show your work<br><br>sqrt110x^17y^12
leonid [27]

Answer:

Step-by-step explanation:

10y2 - 17y + 12 = y + 16

10y2 - 17y + 12 - 16 = y

10y2 - 17y - 4 = y

10y2 -17y - y -4 = 0

10y2 -16y - 4 = 0

Now put formula

x = -b +- (square root) b2 - 4ac

                 2a

a = 10 b= -16 c= -4

y = -(-16) +- (square root) -16 - 4 (10) (-4)

                             2(10)

y = 16 +- (square root) -16 - 400

                                20

y = 16 +- (square root) -416

                         20

y = 16 +- 20.396

              20

Now this +- is the plus minus thingy in which two answers come

The first we will do is +

16 + 20.396                                         16 - 20.396

  20                                                             20

= 1.8198                                                           = -0.2198

Replace a with 25. Replace c with 5.
Then evaluate the expression.

m = 4 * 25 + 2 * 5

m = 100 + 10

m = 110

Answer: 110 meatballs are needed.</span>
