The graph below shows the velocity f(t) of a runner during a certain time interval:graph of line segment going through ordered pairs 0, 6 and 6, 8. Graph of another line segment going through the ordered pairs 6, 8 and 8, 0. Label on the x axis is time in seconds and label on the y axis is velocity in meters per second

Which of the following describes the intercepts on the graph?

The initial acceleration of the runner was 8 m/s2, and the runner stopped after 6 seconds.

The initial acceleration of the runner was 6 m/s2, and the runner stopped after 8 seconds.

The initial velocity of the runner was 8 m/s, and the runner stopped after 6 seconds.

The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds.

Answers

When graphs are plotted, graphs as in the .jpeg image in attachment are obtained.
First graph is line going through ordered pair (point) (0,6) and pair (6,8).
The second graph is line going through ordered pair (6,8) and pair (8,0).
Intercept of these graphs is point (ordered pair) (6,8).
You see from the .jpeg image that the following is true:
Initial velocity of the runner is 6 meters per second (runner starts with this velocity), for a while he runs, velocity grows, then in the 6th second (time=6), runner starts to slow down and velocity starts to decrease, and runner stops totally at time = 8.
So runner stops after 8 seconds.
The 4th claim (sentence) is correct.
First you draw the graph described by the problem to see a better picture of the situation. From the problem the points on the graph are (0,6), (6,8) and (8,0). The first point meant that at time zero the velocity is 6m/s. Then when time is at 8 sec the velocity is zero. The answer to the question is the last choice.

What is the average of the following numbers: 3.2, 47/12,10/3?

Answers

Around 3.48 1/3 using the adding all the numbers and dividing by how many numbers there were
well,3.2=32/10
adding up all the fractions, we get
627/60
to find the average, we have to divide the fraction by 3, (as there are 3 fractions)
the answer is
3.484 approx

the sum of two numbers is 13 2 times the first number minus 3x and the second number is 1 if you let X stand for the first number and why for the second number what are the two numbers

Answers

If we let x be the first number and y be the second, we have (x + y) =13 and (2x - 3y) = 1. From the first equation, we have x = (13- y). Substituting this into the second one, we have 2(13 - y) - 3y = 1. Distributing the equation and re-arranging it, we now have (-5y) = (-26). Dividing both sides by -5, we have y = 5. Now x = (13 - y) = 8. Therefore, the two numbers are 5 and 8.

Adina has a rectangular garden that measures 9 m wide by 13 m long. She wants to increase the area to 192 m^2 by increasing the width and length by the same amount. What will be the width (shorter dimension) of the new garden?Question 4 options:

a) 14 m wide

b) 13 m wide

c) 12 m wide

d) 11 m wide

Answers

area=legnth times width
192=(9+x)(13+x)
solve
expand
192=117+22x+x^2
minus 192 both sides
0=x^2+22x-75
factor
0=(x-3)(x+25)
set to zero

x-3=0
x=3

x+25=0
x=-25
not possible since that gives negative legnths and widhs

increased by 3

shorter is 9
9+3=12

Find the value of x.

Answers

Using the Pythagorean Theorem, we find that x = 10.

To find the value of x, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in any right triangle, the square of the hypotenuse is equal to the sum of the squares of the legs.

In this case, the hypotenuse is x, and the legs are 6 and 8. Therefore, we can write the Pythagorean Theorem as follows:

x^2 = 6^2 + 8^2

x^2 = 36 + 64

x^2 = 100

x = sqrt(100)

Therefore, the value of x is 10.

Here is a more detailed explanation of the Pythagorean Theorem:

The Pythagorean Theorem is a mathematical formula that describes the relationship between the three sides of a right triangle. It states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.

In other words, if a right triangle has sides of length a, b, and c, where c is the hypotenuse (the longest side), then the following equation holds:

c^2 = a^2 + b^2

This equation can be used to find the length of any side of a right triangle, given the lengths of the other two sides.

For example, if we know the lengths of the legs of a right triangle, we can use the Pythagorean Theorem to find the length of the hypotenuse. Or, if we know the length of the hypotenuse and one of the legs, we can use the Pythagorean Theorem to find the length of the other leg.

The Pythagorean Theorem is one of the most important theorems in mathematics, and it has many applications in geometry, trigonometry, and physics. It is also used in many real-world applications, such as surveying, construction, and navigation.
