Question 20
Andrej [43]

The distance between the bottom of the lighthouse and the boat is 77.6m.

<h3>What is the distance between the bottom of the lighthouse and the boat?</h3>

The lighthouse and the boat would form a right triangle. The height would be the height of the lighthouse. The  distance between the top of the lighthouse and boat would be the hypotenuse. The  distance between the bottom of the lighthouse and the boat would be the base.

In order to determine the required distance, Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

  • where:
    a = length
  • b = base
  • c = hypotenuse

125²  = 98²  + b²

b² = 125²  - 98²

b = √(25²  - 98² )

b = 77.6m

If a rock falls from a height of 40 meters on Earth, the height H (in meters) after x seconds is approximately
Julli [10]
Once the rock hits the ground, we know that its height will be equal to 0m
because of this, we can replace H(x) with 0
40 - 4.9 {x}^{2}  = 0
now all we have to do is get x by itself
so..
4.9 {x}^{2}  = 40
then
{x}^{2}  = 40 \div 4.9
{x}^{2}  = 8.1632...
now take the square root of each side
x = 2.857...
2.857 seconds (rounded to the third decimal)

which expression have a value of 16/81? check all that apply. (2/3)^4, (16/3)^4, (4/81)^2, and (4/9)^2
notka56 [123]

Use\ \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}\\\\\left(\dfrac{2}{3}\right)^4=\dfrac{2^4}{3^4}=\dfrac{16}{81}\ :)\\\\\left(\dfrac{16}{3}\right)^4=\dfrac{16^4}{3^4}=\dfrac{16^4}{81}\neq\dfrac{16}{81}\ :(\\\\\left(\dfrac{4}{81}\right)^2=\dfrac{4^2}{81^2}=\dfrac{16}{81^2}\neq\dfrac{16}{81}\ :(\\\\\left(\dfrac{4}{9}\right)^2=\dfrac{4^2}{9^2}=\dfrac{16}{81}\ :)
