Answer:

Step-by-step explanation:

The zeros of the function can be found by factoring. Since this has already been started with completing the square, we will just pick up from where it was left and finish factoring. Set the quadratic equal to 0 first.

(x-8)^2-9=0 then move over the 9:

(x-8)^2=9 "undo" the squaring by square rooting both sides to get

x - 8 = ±3. And then add over the 8 to get the solutions

x = 8 + 3 and x = 8 - 3. The solutions, then, are

x = 5 and x = 11

Answer:

  1. reflection across the origin
  2. rotation 180° about the origin
  3. reflection across the x-axis, and translation right 6 units

Step-by-step explanation:

The figure and its image are symmetrical about the origin, so the following three transformations are equivalent:

  1. reflection across the origin

  2. rotation 180° about the origin

  3. reflection across both x- and y-axes, in either order

__

The figure itself has left-right symmetry, so only one reflection is necessary to map the figure to its image: reflection across a horizontal line. Following that reflection, the image can be put into place by an appropriate translation. One such pair of transformations is ...

  4. reflection across the x-axis and translation 6 units right, in either order

Is this true or false 276 times 13 = 276 times 7 + 276 times 6 = 1,932 + 1,656 and why?
DIA [1.3K]

Answer:

Step-by-step explanation:

13 = 6+7

276*13 = 276*(7+6)

           = 276*7 + 276 *6      {distributive property upod addition}

           = 1932 + 1656

          = 3588

If you pay for $25.00 for purchase which includes 11% sales tax. how much is the sales tax?
Delvig [45]
Since it includes 11% sales tax, this means that (purchase)+11% of (purchase)=25.00. Since 11% = 0.11 by multiplying it by 1/100, we have 1*purchase+0.11*purchase=1.11*purchase=25.00. Dividing both sides by 1.11, we get around 22.73 as the original purchase. This means that the difference between the purchase price and the total price is the sales tax, which is around 2.27 dollars.

a rectangular pool is 8 yards long 6 yards wide and 5 feet deep .convert the measurements of the length and width to feet​
ExtremeBDS [4]

Answer:

1 yard = 3 feet

Keeping this in mind, we need to multiply the yard lengths by 3 to convert the measurements to feet.

8 feet x 3 = 24 yards

6 feet x 3 = 18 yards

5 feet x 3 = 15 yards

So

8 ft = 24 yd

6 ft = 18 yd

5 ft = 15 yd

plz mark brainliest if this helped :)
