Answer:

  • 1. 48 ft²

Step-by-step explanation:

<u>The ratio of sides is </u>

  • Twin/king = 2/3

<u>The area is the product of two sides so the ratio of the areas is the square of the ratio of the sides:</u>

  • A(twin) / A(king) = (2/3)²
  • x/108 = 4/9
  • x = 108*4/9
  • x = 48 ft²

kozerog [31]

Answer:

Smax = 676 ft

the maximum altitude (height) the rocket will attain during its flight is 676 ft

Step-by-step explanation:

Given;

The height function S(t) of the rocket as;

S(t) = -16t2 + 208t

The maximum altitude Smax, will occur at dS/dt = 0

differentiating S(t);

dS/dt = -32t + 208 = 0

-32t +208 = 0

32t = 208

t = 208/32

t = 6.5 seconds.

The maximum altitude Smax is;

Substituting t = 6.5 s

Smax = -16(6.5)^2 + 208(6.5)

Smax = 676 ft

the maximum altitude (height) the rocket will attain during its flight is 676 ft

Does 514, 684, 855 make a right triangle
Naily [24]

Answer:

No, it does not.

Step-by-step explanation:

This does not make a right triangle because in order to have a right triangle you must have 2 of the same numbers.

<em><u>For example:</u></em>

900, 800, 900 makes a right triangle

900, 800, 700 does not.

Hope this helped :D
