<h2>Writing an linear equation from a given scenario</h2>
Answer:
Choice B
<h3>
Step-by-step explanation:</h3>
<em>Please refer to my answer from this question to know more about writing a </em><em>linear</em><em> </em><em>equation</em><em> from a given scenario: </em><em><u>brainly.com/question/24599307</u></em>
Scenario: A submarine dives 
feet per minute.
We let 
, be the position of the submarine from sea level as a function of 
, the time (in minutes) since the submarine dived.
The given scenario states that for every minute, the position of the submarine <u>decreases</u> (because the submarine is going in a downward direction) by feet. So 
can be defined as 
.
Now we can select two points for the graph. We can select points 
and 
.
Evaluation of function:
Our points are 
and 
Choice A doesn't touch our chosen points. In Choice C, it would be the case if the submarine is going in upward direct.
So the correct graph is Choice B.
Answer:
4
Step-by-step explanation:
The constant is the number without a variable, usually being added or subtracted from the variable but not multiplied or divided by it.
Answer:
They are 30.93 in³ altogether.
Step-by-step explanation: V = 4/3 π r³
r = 2.7/2 = 1.35
π x 1.35 x 1.35 x 4/3 = 10.31 in³
10.31 x 3 = 30.93
X = length of shortest side
Therefore the remaining sides will be x +2 and x + 7
x + x + 2 + x +7 = 45
3x + 9 = 45
3x = 36
x = 12
x + 2 = 14
x + 7 = 19
The sides are 12, 14, and 19 cm. long. Hope this helped!
Answer:
(x-54)° + 2x° + 99° = 360
=> x + 2x + 99 – 54 = 360
=> 3x + 45 = 360
=> 3x = 360 – 45
=> x = 315/3
=> x = 105
The value of x is 105
