In the xy-plane, an equation of circle A is
x^2+(y-1)^2=1. Circle B is obtained by shifting
circle A one unit down. Which of the following is an
equation of circle B?
A) x^2+y^2=1
B) x² + (y-2)² = 1
C) (x - 1)^2 +(y – 1)^2 = 1
D) (x + 1)^2 + (y – 1)^2 = 1
Please with explanation
Answer: A
Explanation:
Because the center of circle A is (0,1) and circle B is one unit down, it would be x^2+y^2=1 because the center of circle B is (0,0). (The equation for a circle is (x-h)^2+(y-k)^2=r^2 with h and k as coordinates of the center of the circle and r as the radius.)

B.
(8,6)
C.
(7,5)
D.
(8,5)
Answer:
D. (8,5)
Step-by-step explanation:
What I did was found the slope of the left line and applied that to (6,1)
Answer:
D.
(8,5)
Step-by-step explanation:
Since the top and bottom sides of a parallelogram are congruent (same length), and the bottom side is 5 units long, the missing top right corner must be five units to the right of the point at (3,5).
Solve using the quadratic formula: Y = 2x^2 - 7x-3

Answer:
a) 1 atm
b) 2 atm
c) 3 atm
d) f(x) = (1/33)d + 1
Step-by-step explanation:
a) Surface of the water is the same as 0 depth, and the table shows that when there's 0 depth in feet, there is 1 atm of pressure.
b) Table shows when 33 feet deep, there is 2 atm of pressure.
c) Table shows when 6 feet deep, there is 3 atm of pressure.
d) To make a function equation, you need to find the slope and y-intercept.
The slope is (y2-y1)/(x2-x1), which would be (3-2)/(66-33). This would equal 1/33, which is our slope.
The y-intercept would be the y coordinate of where the x coordinate would equal 0, which would be 1 in this case.
Function equation is y = mx + b
m = slope
b = y-intercept
-> y = (1/33)x + 1

5. Find the vertex and y-intercept of the quadratic function.
y = 3x2 - 12x + 40
The vertex of the function is (2, 28) and the y-intercept of the function is (0, 40)
What are quadratic equations?Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to determine the vertex?The equation of the function is given as
y = 3x^2 - 12x + 40
Differentiate the function
So, we have
y' = 6x - 12
Set the function to 0
So, we have
6x - 12 = 0
This gives
6x = 12
Divide by 6
x = 2
Substitute x = 2 in y = 3x^2 - 12x + 40
y = 3 x 2^2 - 12 x 2 + 40
Evaluate
y = 28
This means that the vertex of the function is (2, 28)
Substitute 0 for x to determine the y-intercept
y = 3 x 0^2 - 12 x 0 + 40
Evaluate
y = 40
This means that the y-intercept of the function is (0, 40)
