A bridge over a river has the shape of a circular arc. The span of the bridge is 24 meters. (The span is the length of the chord

kompoz [17]

Answer:

20 meters

Step-by-step explanation:

Seeing the image attached, we can observe that there is a triangle formed by half of the chord of the arc, the radius (hypotenusa) and part of the radius (r-4). Using pythagoras theorem in this triangle, we have:

(r-4)^2 + 12^2 = r^2

r^2 - 8r + 16 + 144 = r^2

8r = 160

r = 20

So the radius of the circle that contains this arc is 20 meters.

A ball is launched upward at 48 ft/s from a platform that is 100 ft. high. This can be modeled by the equation

LiRa [457]

Answer:

1.5 seconds.

Step-by-step explanation:

The height of ball modeled by the equation:

$h(t)=-16t^2+48t+100$

where, t is time in seconds.

The leading coefficient is negative, it means the given function is a downward parabola and vertex of the downward parabola is the point of maxima.

If a parabola is defined by $f(x)=ax^2+bx+c$ , then the vertex of the parabola is

$\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)$

In the given equation, a=-16, b=48 and c=100.

$\dfrac{-b}{2a}=\dfrac{-48}{2(-16)}=1.5$

$f(\dfrac{-b}{2a})=f(1.5)=-16(1.5)^2+48(1.5)+100=136$

Vertex of the given parabola is (1.5,136).

Therefore, the maximum height of ball is 136 ft after 1.5 seconds.
