A.The observation deck of tall skyscraper 370 m above the street. Determine the time required for a penny to free fall from the
Ainat [17]

Answer:

8.68 seconds

Step-by-step explanation:

Given:

Height of the deck above the street, s = 370 m

Since the condition is of free falling

thus,

initial speed, u = 0

Acceleration of the penny = acceleration due to gravity, g = 9.81 m/s²

Now,

from Newton's equation of motion, we have

s=ut+\frac{1}{2}at^2

here,

s is the distance

a is the acceleration

t is the time

on substituting the values, we get

370=0\times t+\frac{1}{2}\times9.81\times t^2

or

t² = 75.433

or

t = 8.68 seconds

alekssr [168]

Answer:

<h3>The question, </h3>

,

<h3>Let me explain, </h3>

<h3>For infinity many solutions </h3>

They must be parallel to each other,

For instance,

If 4x - 2y = - 2 is the equation then,

<h3>Another equation be 4x - 2y +k = </h3>

Where k can be any numerical value.

20 points!!! Please Help<br><br> Does the equation x2 - 4x + y2 = -3 intersect the x-axis?
OverLord2011 [107]

Answer:

Yes, twice

Step-by-step explanation:

The equation will intersect the x-axis when y = 0, so we have

x² - 4x = -3    now solve this quadratic for x...

  x² - 4x + 3 = 0    

factor...

(x - 3)(x - 1) = 0,

so at x = 1 and x = 3, the function crosses the x-axis

See the graph below
