In triangle, ABD,
AD²= AB²+BD²
AB² = AD²-BD²
AB² = 18²-9² = 324-81 = 243
AB = √243
In triangle, ABC,
AC² = AB²+BC²
AC² = (√243)²+(13)²
AC² = 243+169
AC = √412
AC = 20.29
Answer:
Option A, 
Step-by-step explanation:
<u>Step 1: Determine the numbers that are multiples of 3</u>
8 → Not a multiple of 3
9 → Multiple of 3
14 → Not a multiple of 3
19 → Not a multiple of 3
25 → Not a multiple of 3
34 → Not a multiple of 3
38 → Not a multiple of 3
<u>Step 2: Determine the probability of chosing a multiple of 3</u>
Since we only have 1 number that is a multiple of 3 out of the 7 given numbers, that means that we do the following:


Answer: Option A, 
Answer:
y = 2x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2
The line crosses the y- axis at (0, - 1) ⇒ c = - 1
y = 2x - 1 ← equation of line
