For problem below, make use of the equation of motion of a vertically projected object: 20012 gtv t s  , where sis the heigh

t of the object at time tseconds, gis 32 feet per second² and 0s and 0s are the initial velocity and initial height, respectively.Two friends are in competition. Each stands on the roof of the apartment building where each one lives. At the same time, each friend stands at the edge of the roof and throws up a basketball as hard as possible. Joan’s apartment building is 120 feet high, and she throws the basketball at a speed of 20feet per second. Joe’s apartment building is 105 feet high, and he throws the basketball at a speed of 34feet per second.a)Write the function that describes the height of Joan’s basketball, in terms of time measured in seconds.

Answer:

s=-4.905*t^{2} +20*t+120

The equation corresponds to a quadratic function.

Step-by-step explanation:

Given

s=-\frac{1}{2} gt^{2} +v_{0} t+s_{0}

where

g=9.81\frac{m}{s^{2} }\\  v_{0}=20\frac{ft}{s}  \\ s_{0} =120 ft

the function that describes the height of Joan’s basketball is

s=-\frac{1}{2} (9.81\frac{m}{s^{2} })t^{2} +20\frac{ft}{s}*t+120 ft\\ s=-4.905*t^{2} +20*t+120

The equation corresponds to a quadratic function.

How many solutions are there to the equation 10= a + b + c with each of a, b, and c a whole number greater than or equal to zero
djverab [1.8K]
If <em>a</em> is fixed and <em>b</em>,<em>c</em> are unknowns then the equation <em>b</em>+<em>c</em>=10-<em>a</em> has 11-<em>a</em> solutions. They are pairs (b,c): (0,10-a), (1,9-a), (2,8-a), ... (10-a,0). As <em>a</em> runs from 0 to 10 we have total number of solutions (11-0)+(11-1)+...(11-1)=11+10+...+1=(1+11)*11/2=66.
