This is very easy just alot of terrible numbers lol.

If she goes "down" for 90 SEC  that means she is moving Negative.
So she moves for 90 seconds at a Rate of 3.5 Feet per second
Which means every second she goes down she will subtract 3.5 Ft
Since she is moving for 90 SEC then this will be the equation
 Feet will be negative because she is going down.
-3.5 X 90=?  You might need a calculator.

Now that she has gone down she decided to go up.  For 30 seconds at a different rate. 2.2 Seconds. So now since she is going up it is Increasing. 
Feet will be Positive because she is going up now.
This is the equation 
2.2 X 30=? 
First you want to add both the equations you solved so far.
Now she wants to go to Exactly 0 . So she decides to go up really fast!
So when you get the amount.  She wants to Increase by 4.8 FT Per SEC

So you take the amount you added which should be negative 
And put it into an equation.
 
4.8 Divided by ( the equation you added) = ? SEC

SEC= SECONDS FT= FEET

Y=x(x−2)^3 identify the zeros and their multiplicities.
lawyer [7]
  • The zeros of the function are 0 and 2
  • The multiplicity is the power to which the factors are raised. The multiplicities of the function are 1 and 3.

<h3>Zeros and multiplicities of functions</h3>

Given the function y=x(x-2)^3

The zeros of the function is at the point where y = 0

x(x-2)^3 =0\\x = 0\\(x-2)^3=0\\x-2=0\\x=2

Hence the zeros of the function are 0 and 2

The multiplicity is the power to which the factors are raised. The multiplicities of the function are 1 and 3.

A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t where t equals the
Stolb23 [73]

Answer:

  • t = 1.5; it takes 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground.

Explanation:

<u>1) Explanation of the model:</u>

  • Given: h(t) = -16t² + 48t

  • This is a quadratic function, so the height is modeled by a patabola.

  • This means that it has a vertex which is the minimum or maximu, height. Since the coefficient of the leading (quadratic) term is negative, the parabola opens downward and the vertex is the maximum height of the soccer ball.

<u>2) Axis of symmetry:</u>

  • The axis of symmetry of a parabola is the vertical line that passes through the vertex.

  • In the general form of the parabola, ax² + bx + c, the axis of symmetry is given by x = -b/(2a)

  • In our model a = - 16, and b = 48, so you get: t = - ( 48) / ( 2 × (-16) ) = 1.5

<u>Conclusion</u>: since t = 1.5 is the axys of symmetry, it means that at t = 1.5 the ball reachs its maximum height and that it will take the same additional time to fall back to the ground, whic is a tolal of  1. 5 s + 1.5 s = 3.0 s.

Answer: t = 1.5; it takes 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground.

'Ciumane ananen<br> 32.50t + 5 = 28.75t + 20
gtnhenbr [62]

Answer:

The answer is 0.25

Step-by-step explanation:

(1)we group like terms by subtracting 32.50 by 28.75

(2) we subtract 20 and 5 to give us a value of 15

(3)when we subtract 32.50 and 28.75 we get a value of 3.75

(4)so the equation will look like this 3.75t = 15

(5)we divide 3.75 we both the two equations

(6)With a correct calculation, Your answer should be t = 0.25
