Answer:
(A, B, C) = (2, 5, 2)
Step-by-step explanation:
Undo the square operation by taking the square root. Both the positive and negative square roots are solutions to the equation.
[tex]c -2 = \pm\sqrt{50}[/tex]
Add 2 to both sides of the equation:
[tex]c = 2\pm\sqrt{50}[/tex]
Simplify the square root:
[tex]c=2\pm\sqrt{25\cdot2}=2\pm\sqrt{25}\cdot\sqrt{2}\\\\\boxed{c=2\pm5\sqrt{2}}\qquad\text{A=2, B=5, C=2}[/tex]

Additional comment
Square roots are simplified by factoring out the factors that are perfect squares.

Which of the following values of x would not be in the domain of the function defined by f(x) = x-2/x+3?
Answers
Answer:
x = 7 is not there in the domain of the function.
Step-by-step explanation:
The value of x = -3 would not be in the domain of the function
We have the following information available from the question is:
The function is :
[tex]f(x) =\frac{x-2}{x+3}[/tex]
Determine the values of x would not be in the domain of the function
Now, According to the question:
The function is :
[tex]f(x) =\frac{x-2}{x+3}[/tex]
Let the denominator equal to zero: x + 3 = 0
Rearrange unknown terms to the left side of the equation.
x + 3 = 0
x = -3
Hence, The value of x = -3 would not be in the domain of the function.

A circle on the coordinate plane has a diameter

a. What are the coordinates of the center of the

b. What is the diameter of the circle?
C. What is the radius of the circle?
d. Identify the coordinates of another point
on the circle. Explain how you found
your answer.
Answers
9514 1404 393
Answer:
a. (10.5, 8)
b. 9
c. 4.5
d. (10.5, 12.5)
Step-by-step explanation:
a. The center of the circle is the midpoint of the diameter. Its coordinates are the average of the end point coordinates.
C = ((6,8) +(15, 8))/2 = (21, 16)/2 = (10.5, 8) . . . circle center
__
b. The diameter lies on the horizontal line y=8, so its length is the difference of the x-coordinates of the end points: 15 -6 = 9 . . . circle diameter
__
c. The radius is half the diameter: 9/2 = 4.5 . . . circle radius
__
d. Another point on the circle will be 4.5 units from the center on the same vertical line: (10.5, 8) +(0, 4.5) = (10.5, 12.5) . . . another point on the circle

It takes an elevator 2 seconds to go from floor to floor. Each passenger
takes 1.5 to 2.0 seconds to board or exit. Twelve passengers board on the
first floor and exit on the fourth floor. How long will you wait if you are on
the seventh floor and ring for the elevator just as it leaves the first floor?
Answers
Answer:
38 seconds
Step-by-step explanation:
just take 2x7 for the elevator taking the time to reach your floor which is 14 seconds. then just add on the additional time that all the passengers take to get off the elevator as it's only counting the time since it starts moving. that is 12x2=24. now just add 24+14 and you get your answer of 38

The volume of a cylinder is found by using the formula V = pi x r^2 x h where r is the radius and h is the height.
Using the given volume and radius calculate the height:
169.56 = pi x 1.5^2 x h
169.56 = pi x 2.25 x h
169.56 = 7.065 x h
H = 169.56/7.065
H = 24 inches
The answer is the height is 24 inches

Answer:
$8 an hour
Step-by-step explanation:
1.) 92 - 20 = 72
2.) 3 x 8 = 24
3.) 6 x 8 = 48
4. 24 + 48 = 72
OR
1.) 92 - 20 = 72
2.) 6 + 3 = 9
3.) 72 / 9 = 8
either way to solve gives you the correct answer as shown above. Also if answer is correct please leave ”thanks” heart
