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

Answers

Answer 1

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.)

Answer:

B. Same-side interior angles

Step-by-step explanation:

Angle w and angle x lie on the same side of the transversal that cut across the two parallel lines, and are also within the two parallel lines. They are therefore regarded as same-side interior angles. Same-side interior angles are supplementary.

Amelia was showing off her basketball skills. She scored a total of 14 shots for a total of 32 points. How many 2 point and 3 point shots did she make?

Answers

Answer:

Step-by-step explanation:

x+y=14

y=14-x

2x+3y=32, using y=14-x we have

2x+3(14-x)=32

2x+42-3x=32

-x+42=32

-x=-10

x=10, and since y=14-x

y=14-10=4

So Amelia made 10 two-pointers and 4 three-pointers.

Option C is the correct answer.

What is a triangle?

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

ΔABD is similar to ΔBCD.

This means,

The corresponding sides ratio is equal.

AB/BC = BD/CD = AD/BD

AB/m = BD/7 = 11/BD

Now,

BD/7 = 11/BD

BD² = 77

BD = √77

Now,

ΔBDC

BC² = CD² + BD²

m² = 7² + 77

m² = 49 + 77

m² = 126

m = √126

Thus,

The value of m in the figure is √126.

Answer:

  (x, y) = (3, 7)

Step-by-step explanation:

If you divide the second equation by 2, it becomes ...

 -x +2y = 11

Adding this to the first equation gives you the value of y:

  (x -y) +(-x +2y) = (-4) +(11)

  y = 7 . . . . . . . . simplify

The first equation can be rearranged to give an expression for x:

  x = y -4

  x = 7 -4 = 3

Then the solution is seen to be (x, y) = (3, 7).

what is the capacity in litres of a rectangular tin that measures 20m by 20cm by 10cm​

Answers

Answer:

0.4 liters

Step-by-step explanation:

Volume: length x width x height

Volume: 20 x 20 x 10

Volume: 400 cm cubed

1 cubic cm = 0.001 liters

400 cm cubed = 0.4 liters

You use the formula Length x Width x Hight. Which gets you 20x20x10 getting you 4000 then 1 cm is 0.001 of a liter which gets you 400cm or 0.4 liters.
