Write the standard equation of the circle with the given center and passes through the given point. Center (7,-2); Point= (1,-6)
vodomira [7]

Answer:

(x - 7)² + (y + 2)² = (2√13)²

Step-by-step explanation:

We already know that the center is at (7, -2), but must find the radius.  The radius is the distance between the points (7, -2) and (1, -6):

r = √ [6² + 4²] ) = √(36 + 16) = √52 = √4√13 = 2√13.

Then the desired equation is (x - 7)² + (y + 2)² = (2√13)²

The correct scientific notation for the number 500.0 is
marishachu [46]

Answer:

The correct scientific notation for the number 500.0 is 500=5.0\times10^2

Step-by-step explanation:

While writing a large number in scientific notation we do below mentioned two things.

  • We take any number between 1 and 10
  • Then we multiply this number with an exponent of 10.

Hence, any number in scientific notation is in the form a\times10^b

Here a is any number between 1 and 10.

b is exponent of 10.

Now, writing 500 in scientific notation, we take a = 5

Hence, we have to take b = 2, since 5 multiplied by 100 equas 500.

Thus, we have

500=5.0\times10^2

Three DVDs and four CDs cost $92. Two DVDs and three CDs cost
Vedmedyk [2.9K]

Answer:

DVD: $16

CD: $11

Step-by-step explanation:

These two linear equations can represent the system of equations where x equals the cost of a DVD and y equals the cost of a CD:

3x+4y=92

2x+3y=65

When graphed, the solution is at (16,11).

Therefore, one DVD costs $16 and one CD costs $11.
