Issac tosses a quarter off of a bridge, creating the shape of a parabola. The parabola can be represented by the equation h=-16t
andreyandreev [35.5K]

Answer:

Step-by-step explanation:

a) the equation representing the parabola is expressed as

h = -16t² - 4t + 20

c) to determine the height after 25 seconds, we would substitute 25 for t into the given equation. It becomes

h = -16(25)² - 4(25) + 20

h = - 10000 - 100 + 20

h = - 10080

d) when the coin lands on the ground, the height would be 0. Therefore,

-16t² - 4t + 20 = 0

Dividing both sides of the equation by 4, it becomes

- 4t² - t + 5 = 0

- 4t² - 5t + 4t + 5 = 0

- t(4t + 5) + 1(4t + 5) = 0

- t + 1 = 0 or 4t + 5 = 0

t = 1 or t = - 5/4

Since t cannot be negative, then t = 1 second

What is the value of x? <br><br> 5 sqrt 2<br> 10 sqrt 2<br> 5<br> 10
vitfil [10]
Hey there! :D

So, basically, you could say that "x" is equal to both of the legs. 

We also know that in 45-45-90 triangles, x*√2= the hypotenuse

Given this information, if we were to divide 10 by the √2, we would get:

10/√2= 7.071..... 

5√2= 7.071....

5√2 is the answer. 

I hope this helps!
