Divide both sides by pir^2
h = v / pir^2 Answe
Answer:
x=4.5 and y= -6
Step-by-step explanation:
2x+5y= -21
-2x+3y= -27
add the two equations: 8y= -48
y=-48/8= -6
sub for y in 2x+5y= -21
2x + 5(-6)=-21, 2x-30= -21
2x= -21+30= 9
x= 9/2=4.5
Answer:
24.5
Step-by-step explanation:
7^2=49
49/2=24.5
Answer:
As the given equation represents a quadratic function.
Thus, represents a function.
As we know that the function is just a relation in which each input has only one output.
Thus, represents a relation and function.
Step-by-step explanation:
Given the equation
As the given equation represents a quadratic function.
Thus, represents a function.
As we know that the function is just a relation in which each input has only one output.
Thus, represents a relation and function.
We know that the domain of a function is the set of input or argument values for which the function is real and defined.
We also know that the range of a function is the set of values of the dependent variable for which a function is defined.
The graph is also attached below. From the graph, it is clear that it represents a Parabola.
Answer:
Soleil and Malvin would have $ 5,000 all together after 13 days.
Step-by-step explanation:
Since Soleil and Malvin each work a job, and Soleil starts with $ 700 and makes $ 100 per day while Malvin starts out with $ 200 and makes $ 120 per day, to determine after how many days will they have at least $ 5000 all together it must be done the following calculation:
5,000 - 700 - 200 = 4,100
200X + 120X = 4,100
320X = 4,100
X = 4,100 / 320
X = 12.8
So Soleil and Malvin would have $ 5,000 all together after 13 days.
