Domain of fg(x) is determined by the domain of g(x).g(x) has domain such that x is any real number.So domain fg(x) is x such that x is any real number.
Answer:
77 feet below sea level.
Step-by-step explanation:
Since y is the time the submarine is ascending, we can plug it in for y and find our answer. We can create an equation where D is the depth and y is time ascending: D = -230 + 17y
Substitute 9 for y:
D = -230 + 17(9)
D = -230 + 153
D = -77
The depth of the submarine after 9 minutes will be 77 feet below sea level. Hope this helps, and Brainly will be highly appreciated.
Angle 12 and Angle 10 are vertical angles.
Answer:
89
Step-by-step explanation:
Hi, there to find the mean
you need add the numbers and count how many numbers are there and divide
In this case 98+78+84+96= 356
Now we will count
there are 4 numbers
= 89
Your mean will be 89
If you ever have trouble with mean remember this
Mean
well it is supposed to be:
Sum of Data Points/Number of Data Points
Answer:
Step-by-step explanation:
we have to use the formula of slope here.
we know,
slope of the line passing through (x1,y1) and (x2,y2) is-

Here, the first two points are -
(-4 , 5) and (0,6)
So, the slope will be-

So, the slope is-
