Answer:
It's a two rotation angles that have the same measure.
The falling distance of the glasses is 8 meters.
<h3>How to calculate the distance</h3>
From the information, the hotel’s balcony was 5 meters from the ground floor and he dropped his glasses to the bottom of the hotel’s pool that was 3 meters deep.
Therefore the falling distance will be:
= 5 - (-3)
= 5 + 3
= 8

Answer: c.A is the set of rational numbers
Step-by-step explanation:
B ⊆ A means that every element of B is an element of A
B = { -13 , -9 , -7 , - 3 }
The element of B are negative integers , this mean that the element of A must also be integers therefore :
Option a is correct.
Option b is also correct
Rational numbers are numbers that can be express in the form a/b , examples are : 1/2 , 3/ 4 , 5/6 ...
clearly , this does not necessarily define A , so option c is the odd one out
Answer:
a
Step-by-step explanation:
//I'll use the discriminant rule for this.
b^2 - 4ac = 0 when one real root
Therefore, k^2 - 4*3*4= 0
k^2 = 48
k= +-4√3
