m∠ABC = [tex]\frac{1}{2}[/tex] m∠AOC = 54°
Answer: 54°
because ∠ADC is the angle at the center of the arc AC and ∠ABC is the inscribed angle of the arc AC
=> m∠ABC = 1/2. m∠ADC = 108/2 = 54°

The price of the original shirt is $45, it is reduced to $32.50. Calculate the percentage decrease. Show your workings.
Answers
Answer:
The percent decrease in the price of shirt is 27.78%
Step-by-step explanation:
The percent decrease is the decrease in the price of a product or good.
Given
Original Price = $45
Decreased price = $32.50
Percentage decrease is calculated by using the formula
[tex]Percentage\ decrease = \frac{decrease}{Original\ price} *100\\[/tex]
And the decrease is calculated as:
[tex]Decrease = Original\ price - Reduced\ price[/tex]
So,
[tex]Decrease = 45-32.50 = 12.5[/tex]
Putting the values in the formula for percent decrease
[tex]Percent\ decrease = \frac{12.50}{45} *100\\=0.2777..*100\\= 27.77..[/tex]
Rounding off to nearest hundredth: 27.78%
Hence
The percent decrease in the price of shirt is 27.78%

- 5x = 45 ( divide both sides by - 5 )
x = - 9

f(x)=-x²-2x-8 determine the vertex
Answers
Answer:
vertex = (- 1, - 7 )
Step-by-step explanation:
Given a parabola in standard form, f(x) = ax² + bx + c (a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
f(x) = - x² - 2x - 8 ← is in standard form
with a = - 1 and b = - 2, then
[tex]x_{vertex}[/tex] = - [tex]\frac{-2}{-2}[/tex] = - 1
Substitute x = - 1 into f(x) for corresponding y- coordinate
f(- 1) = - (- 1)² - 2(- 1) - 8 = - 1 + 2 - 8 = - 7
vertex = (- 1, - 7 )
We can use a shortcut such that:
