C. They will have the same solution because they represent the same lines when plotted on the coordinate axes
I believe its A, since the absolute value brackets are used to show how far away a number is from 0. All of the other answers are correct, but A makes the most sense here.
Answer:
<em>16 feet</em>.
Step-by-step explanation:
Please refer to the attached diagram for the clear understanding of the given question statement.
A is the position of tour guide on deck.
B is the sea level. (Can be considered as zero on the number line)
C is the position of Diver and
D is the point on ocean floor.
Below sea level dimensions are given as negative in the question statement.
As per given statement,
AB = 5 feet
BC = 11 feet (Ignoring the negative sign as negative sign only depicts that it is below sea level)
BD = 18 feet
To find:
Distance from tour guide to the diver = ?
Solution:
We have to actually find the value of AC here as per the image attached.
AC = AB + BC = 5 + 11 = <em>16 feet</em>
There are 70 degrees in angle A.
Answer: x = 1.788587
Step-by-step explanation: 3^2 − 1 - 12. 3^X + 81 = 0
-12^X + 89 = 0
-12. 3^X + 89 + -89 = 0 + -89
-12. 3^X = -89
-12. 3^X/-1 = -89/-1
12. 3^X = 89
log (12.3^X) = log (89)
x * (log (12.3)) = log (89)
x = log (89)/ log (12.3)
x = 1.788587
