Answer:

x=(59cos 45\textdegree)t,y=4+(v_0sin45\textdegree)t-16t^2

Step-by-step explanation:

From the question we are told that

Height h=4feet

Initial velocity ofv_0=59 feet/sec

Angle \theta= 40\textdegree

Generally the parametric equation for projectile motion is mathematically given by

x=(v_0cos\theta)t,y=y_0+(v_0sin\theta)t-16t^2

Therefore

x=(59cos 45\textdegree)t,y=4+(v_0sin45\textdegree)t-16t^2

The parametric equation that represents the path of the football

x=(59cos 45\textdegree)t,y=4+(v_0sin45\textdegree)t-16t^2

Find the solution of the recurrence relation an = 3an−1 −3an−2 +an−3 if a0 = 2, a1 = 2, and a2 = 4.
Shkiper50 [21]

Using the recurrence relation, we can find a couple more values in the sequence:

  • a3 = 3a2 -3a1 +a0 = 3(4) -3(2) +2 = 8
  • a4 = 3a3 -3a2 +a1 = 3(8) -3(4) +2 = 14

First differences are 0, 2, 4, 6, ...

Second differences are constant at 2, so the function is quadratic.

The sequence can be described by the quadratic ...

... an = n² -n +2

_____

We know the value for n=0 is 2, so we can find <em>a</em> and <em>b</em> using the given values for a1 and a2.

... an = an² +bn +2

... a1 = 2 = a·1² +b·1 +2 . . . . for n=1

... a + b = 0

... a2 = 4 = a·2² -a·2 +2 . . . . for n = 2; using b=-a from the previous equation

... 2 = 2a

... a = 1 . . . . so b = -1

One of the legs of a right triangle is 9 cm. If the area of the triangle is 225 cm², then the length of the other leg is
ioda

Given:

One of the legs of a right triangle is 9 cm.

The area of the triangle is 225 cm².

To find:

The length of the other leg.

Solution:

The area of a triangle is

Area=\dfrac{1}{2}\times Base\times Height

The area of a right triangle is

Area=\dfrac{1}{2}\times (leg_1)\times (leg_2)

Let x be the length of other leg.

225=\dfrac{1}{2}\times (9)\times (x)

2\times 225=9x

\dfrac{450}{9}=x

50=x

Therefore, the length of the other leg is 50 cm.
