Answer:

Yes this is a proportional relationship.

Equation is;

D=20T

Step-by-step explanation:

A horse run;

800m in 40 seconds

1200m in 60 seconds

and

480m inn 24 seconds

800m ÷ 40s = 1200m ÷ 60s = 480m ÷ 24s = 20

The equation here is Distance(D) = 20 × Time(T)

D=20T

It implies that the distance of the horse is directly proportional to the time it takes to run.

Projectile Is shot upward from the surface of Earth with an initial velocity of 136 meters per second. Use the position
Anna007 [38]

Answer:

v(3\,s) = 106.6\,\frac{ft}{s}, v(15\,s) = -11\,\frac{ft}{s}

Step-by-step explanation:

The velocity function of the projectile is obtained by deriving the position function:

v(t) = -9.8\cdot t + 136

Now, the velocities after 3 and 15 seconds are, respectively:

v(3\,s) = -9.8\cdot (3) + 136

v(3\,s) = 106.6\,\frac{ft}{s}

v(15\,s) = -9.8\cdot (15) + 136

v(15\,s) = -11\,\frac{ft}{s}

A community center rents their hall for special events. They charge a fixed fee of $200 plus an hourly fee of $22.50. Lin has $3
Karo-lina-s [1.5K]

Answer:

No, 6 hours would cost $335, 35 over her limit of $300.

Step-by-step explanation:

she has to pay $200 plus 22.50 for every hour she rents. So, if she rents for 6 hours, she has to pay $200 + 6(22.50) or $200 + 135=335. She only has $300 so she can’t afford the event.

-\frac{9}{15}

-0.7

Step-by-step explanation:

Both -\frac{9}{15} and -0.7 are negative so therefore, 1 is the greatest

-\frac{9}{15} is -0.6 which is greater than -0.7 so it's the 2nd greatest

and -0.7 is the least
