Answer:
3 term
Step-by-step explanation:
Count the amount of numbers between operations
Start by pulling out a three
y = 3(x^2 - x - 2) Now it is much easier.
y = 3(x - 2)(x + 1)
Answer:
Step-by-step explanation:
You need to remember the Negative exponent rule:
Then, having the equation , you can rewrite it in this form:
Now add 2 to both sides of the equation:
Multiply both sides of the equation by "x":
And finally divide both sides of the equation by 27.
The value of "x" is:
Answer:
a)
b)
Step-by-step explanation:
a) Area of Sector AOB =
Where r = 8, θ = 41.8 degrees
<u>Firstly, Angle in Radians</u>
=> 41.8 degrees = 0.73 radians
So,
Area of Sector AOB =
Area of Sector AOB =
Area of Sector AOB = 23.3 units²
b)<em> Finding the length of minor arc AB</em>
So,
Arc Length = Radius ×
Where Radius = 8, = 0.73 radians
Arc Length AB = 8 * 0.73
Arc Length = 5.84 units
