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

The bases of the trapezoid are 6 and 10. The height is 4. Find the area.
ollegr [7]
Answer

b. 32 sq. unit

Step-by-step Explanation

The area of the trapezoid is given by

A = \frac{1}{2} (b_{1} + b_{2}) \times h

We substitute the given values into the formula to obtain;

A = \frac{1}{2}(10 + 6) \times 4

Simplify

A = \frac{1}{2} (16) \times 4

A = 16 \times 2
Hence the area is

A = 36 \: sq \: units

PLEASE HELP im super confused
FinnZ [79.3K]

Answer:

7 Quarters and 3 dimes

Step-by-step explanation:

You have to find how many quarters (0.25) and dimes (0.10) are in $2.05. There are 7 quarters, which will add up to $1.75. You can't have 8 quarters because then you would have 2 dollars, and there wouldn't be enough for a dime, there would only by 5 cents left, or a nickle. Then, you find out how many nickels you need, which is 3.

.10x3=.30. 1.75+0.3=2.05.

I hope you understood:)

Answer:

  • 21°

Step-by-step explanation:

A boat captain, lighthouse and its base form a right triangle.

<u>We need to find the angle opposite to 22 ft side:</u>

  • tan x = 22/103
  • x = arctan (22/103)
  • x = 21°

<em>Note, option D should read 21° not 11°</em>

PLEASE HELP ASAP
Lesechka [4]

Answer:

A. f and h

Step-by-step explanation:

For a linear function the First Differences of the y-values must be a constant. i.e. if we take the difference between any two consecutive y values or values of f(x) it should be the constant. For this rule to work, x values must change by the same number every time, which is true for all three given functions.

For function f:

The values of f(x) are: 5,8,11,14

We can see the difference in consecutive two values is a constant i.e. 3, so the First Difference is the same. Hence, function f is a linear function.

For function g:

The values of g(x) are: 8,4,16,32

We can see the difference among two consecutive values is not a constant. Since the first differences are not the same, this function is not a linear.

For function h:

The values of h(x) are: 28, 64, 100, 136

We can see the difference among two consecutive values is a constant i.e. 36. Therefore, function h is a linear function.
