To win the game, a place kicker must kick a football from a point 45 m (49.212 yd) from the goal, and the ball must clear the cr

V125BC [204]

Answer:

1.65m

Step-by-step explanation:

First, we have to know the velocity of the ball in both axis, x-axis and y-axis.

Vy = sen(32.6°)*24m/s = 12.9m/s

Vx = cos(32.6°)*24m/s = 20.2m/s

Now, we are told the distance covered by the ball, which es 45m (x-axis). With that info, we can find the time the ball traveled, by x=v*t

x = distance in x-axis and Vx = 16.85m/s

Clearing t, we have: t = x / Vx = 45m / 20.2m/s = 2.2s

Finally, using the equation of vertical distance: Dy = 1/2 a*t² + V0y*t

Dy = (1/2*-9.8m/s²*2.2s²) + 12.9m/s*2.2s = -23.7m + 28.4m = 4.7m

The ball cleared the croosbar by 4.7m-3.05= 1.65m

Trava [24]

Answer:

$y = \frac{1}{-1}x + 0$ $or$ $y = \frac{1}{-1}x$

Step-by-step explanation:

$y = mx + c$

$m = \frac{y_{2} -y_{1}}{x_{2} - x_{1} } }$

$(x_{1},y_{1}) = (-1,1)\\(x_{2},y_{2}) = (-2,2)$

$m = \frac{2 - 1}{(-2) - (-1)}$

$m = \frac{2 - 1}{-2 +1 }$

$m = \frac{1}{-1}$

$c = 0$

$y = \frac{1}{-1}x + 0$ $or$ $y = \frac{1}{-1}x$

A certain population of bacteria has an initial population of 225. the bacteria triples every hour. determine the multiplier tha

dimaraw [331]

Using an exponential function, it is found that the multiplier that would allow you to predict the population of bacteria after 2 hours is of 9.

<h3>What is an exponential function?</h3>

An exponential function is modeled by:

$y = ab^x$

In which:

a is the initial value.

b is the growth rate.

In this problem, the bacteria triples every hour, hence the rate of change is b = 3, and the equation is:

$y = a(3)^x$

Hence, after 2 hours:

$y = a(3)^2 = 9a$

Which means that the multiplier is of 9.
