Help!! YEEEEEEEEEEEEEEEEEET

Mathematics
1 answer:
timofeeve [1]3 years ago
3 0

Answer:

Step-by-step explanation:

Degree of quadratic equation is 2

So, y = (x + 2)² - 6    ; y = x² - 4x + 2  & y = -(x -2)² + 5  are quadratic equation

(a + b)² = a² + 2ab + b²

y = (x + 2)² - 6

y = x² + 2*x*2 + 2² -6

y= x² + 4x + 4 -6

y= x² + 4x - 2

Degree = 2    

y = -(x - 2)² + 5

y = -[ x² - 2*x*2 + 2²] + 5

y = -[x² - 4x + 4)+5

y = -x² + 4x - 4 + 5

y = -x² + 4x + 1

Degree = 2

At Dizzy World theme park, Vera waited in line for 35 minutes and rode on a Magical Mushroom for 7 minutes. What is the percent
IgorLugansk [536]

Answer: the percent value-added time for this ride is 16.67%

Step-by-step explanation:

 Given that;

Waiting time for Vera = 35 minutes

Length of Vera's ride = 7 minutes

total processed time will; ( 35 + 7 ) = 42 minutes

the percent value-added time for this ride = ?

so

Percentage value-added time of Vera will be

= (length of the ride / total process time) × 100

we substitute

⇒ (7 / 42) × 100

⇒ 0.16666 × 100

⇒ 16.67%

Therefore the percent value-added time for this ride is 16.67%
