Mathematics
1 answer:
sertanlavr [38]3 years ago
8 0

Answer:

See Below

Step-by-step explanation:

Thankfully, all the parts you need are given.

First, find the surface of one triangle

A = 1/2bh

A = 1/2(15)(9)

A = 1/2(135)

A = 67.5

Multiply by 4 to get the sum of all the sides.

67.5(4) = 270

Now find the surface area of one square

A = bh

A = (15)(15)

A = 225

multiply by 5 to get all 5 sides

225(5) = 1125

Add sums together

1125 + 270 = 1395

The distance that an object falls from rest, when air resistance is negligible, varies directly as the square of the time that i
Amiraneli [1.4K]

Answer:

\boxed{301865\:feet}

Step-by-step explanation:

Let the distance be d and the time be t.


It was given that the distance, d, varies directly as the square of the time t, we write the proportional relation,


d\propto t^2.


\Rightarrow d=k t^2, where k is the constant of variation.


It was also given that, d=193,193, when t=44.


\Rightarrow 193193=k (44^2)


\Rightarrow 193193=1936k


\Rightarrow \frac{193193}{1936}=k


\Rightarrow k=99.79


Now the equation of variation becomes;

d=99.79t^2


When, t=55s, d=99.79(55^2)


\Rightarrow d=99.79(3025)


d=301864.75

The object will travel 301865 feet in 55 seconds.
