Answer:</h2>
A.) {-6, -2, 5}
<h2>
Step-by-step explanation:</h2>
A function 
from a set 
to a set 
is a relation that assigns to each element 
in the set exactly one element 
in the set . The set is the domain (also called the set of inputs) of the function. From the figure, we can see that this set is the x-coordinate of each red point. So this set is {-6, -2, 5}
Answer:
none of them
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 0.5 × base × perpendicular height
Here the base is BC and perpendicular height is AD, hence
Area of ΔABC = 0.5 × BC × AD
A modulus is pretty much just the square root of x^2 + y^2, where y is the number that stands with the imaginary “i” and x is the real number. In this case, x is 2 and y is 3, so your modulus would be the square root of 4 + 9 (2^2 + 3^2), or the square root of 13.
Answer:
5.673091 x 10^6
Step-by-step explanation:
Number is n
Three times the sum of a number and 4.
= 3* ( n + 4) = 18
3n + 12 = 18.
3n = 18 - 12.
3n = 6
n = 6 / 3.
n = 2.
