Answer:

28 +10√381 -30√254 +36√2

Step-by-step explanation:

It is useful to remember the form for the square of a binomial.

  (a +b)² = a² +2ab +b²

  (a -b)² = a² -2ab +b²

__

1. (5 +√3)² = 5² +2·5·√3 +(√3)² = 25 +10√3 +3

  = 28 +10√3

__

2. (√6 -5√3)² = (√6)² -2·√6·5√3 +(5√3)² = 6 -30√2 +75

  = 81 -30√2

__

3. (6 +3√2)² = 6² +2·6·3√2 +(3√2)² = 36 +36√2 +18

  = 54 +36√2

What is the area of a rectangle with the length 14 1/2 inches and a width of 5 2/3 inches

Answers

Answer:

A = 82 1/6 in^2 (frac. form)

or

A = 82.17 in^2 (dec. form)

Step-by-step explanation:

A = l*w

A = (14 1/2)(5 2/3)

A = (29/2)(17/3)

A = 82 1/6 in^2 (frac. form)

or

A = 82.17 in^2 (dec. form)

An object is dropped from a height of 1168 feet above the ground.

How high above the ground will the object be after 6 seconds?
Incorrect
feet
Correct

How long after being dropped will the object reach the ground? (if necessary, round to the nearest tenth)

Answers

9514 1404 393

Answer:

  592 feet

  8.5 seconds

Step-by-step explanation:

The usual equation used for ballistic motion is ...

  h(t) = -16t^2 +h0

Here, we have h0=1168 and t=6, so ...

  h(t) = -16(6^2) +1168 = 592 . . . feet high after 6 seconds

__

For h(t) = 0, the value of t can be found from ...

  0 = -16t^2 +1168

  t^2 = 1168/16 = 73

  t = √73 ≈ 8.5

The object will reach the ground after 8.5 seconds.
