We have been given that the ball is tossed into air at a speed of 20 feet per second and from a height of 7 feet.
We are supposed to use the formula:
Upon substituting the given values of initial velocity and initial altitude, we get:
We need to figure out the time that will take the ball to reach the ground. In order to do so, we will substitute s(t)=0 and solve for t.
Upon using quadratic formula, we get:
Upon finding the values of t using calculator, we get t=-0.285, 1.535
Therefore it will take the ball approximately 1.54 seconds to hit the ground.
Answer:
Step-by-step explanation:
basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.
first, you need to factor out the equation.
start with the original equation.
V=4x^3+10x^2+4x
factored form:
V= 2x(2x^2+5x+2)
next, you're going to want to plug in the values.
the answer asks for x=4, but you should do both.
v=2(3)(2(3)^2+5(3)+2)
do not forget to do the exponents before!
v=6(18+15+2)
v=6(35)
v=210 ft^2
that's the answer for if x was equal to 3.
V= 2x(2x^2+5x+2)
<em>don't forget to write the original equation first. </em>
V=2(4)(2(4)^2+5(4)+2)
<em>V=8(36+20+2)</em>
<h2>
<u><em>V=464 ft^2 </em></u></h2>
⬆is your answer! hope this helped!!
