Complete the square of x^2-2x+17
Answers
Answer:
(x - 1)² + 16
Step-by-step explanation:
x² - 2x + 17 = 0Subtract 17 from both sides of the equation.
x² - 2x = -17Use the formula (b/2)² to see which number you have to add to both sides.
(-2/2)² = 1Add 1 to both sides of the equation.
x² - 2x + 1 = -17 + 1Factor the left side of the equation into a perfect square.
(x - 1)² = -16Add 16 to both sides of the equation.
(x - 1)² + 16(x - 1)² + 16 is the equation in standard form (x² - 2x + 17) rewritten by completing the square.

Answer: b =50°
Step-by-step explanation:
The angles on a straight line =180°
180° = 50°+90°+b
180°-50°-90°=b
50° = b
Answer:
Step-by-step explanation:
∠b + ∠a + 50° = 180°
∠b + ∠90 + 50° = 180°

Aregular hexagon is dilated by a scale factor of 0.4 to create a new hexagon. The perimeter of the new hexagon is 0.4 times the perimeter of
the original hexagon
O True
False
Answers
Answer:
True.
Step-by-step explanation:
It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.
It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.
For example,
Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32
Let's find image using scale factor 0.4, we get
length =0.4(12)= 4.8
width =0.4(4)=1.6
So, perimeter of image = 4.8+4.8+1.6+1.6=12.8
If we compare the perimeters
0.4(32)=12.8.
So, it is true.

The store paid 2.50 for a book and sold it 5.25%. What is the percent?
Answers
profit as a percent = (price sold - purchase price) / (purchase price)
profit as a percent = (5.25 - 2.50 ) / (2.50)
profit as a percent = 2.75 / 2.50
profit as a percent = 1.1
then we will multiply 1.1 by 100 to get a percentage
profit as a percent = 110%
