<h3>What is a circle?</h3>
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
Given the radius of the circle is 8 units, while the angle of the sector is 74°. Therefore, the area of the sector is,
Area of the sector = π×R²×(74/360)
= π × 8² × 0.20556
= 41.346 units²
Hence, the area of the sector PQR is 41.346 units².

Answer: Sample space for:
Coin (S) ={H, T}
Spinner (S) = {Green, Red, Orange, Purple, Yellow}
All the Possible outcome for:
Coin =1
Spinner = 1
The total outcome there = 7
Probability of flipping tails and not spinning purple or green
=11/10
Step-by-step explanation:
All the Possible outcome for:
Coin =1/2+1/2=1
Spinner = 1/5+1/5+1/5+1/5+1/5=1
The probability of flipping tails. = 1/2
The probability of not spinning purple or green = 3/5
Therefore, the probability of flipping tails and not spinning purple or green
= 1/2+3/5
=11/10
4x^2 + 9xy - y^2 = 8
8x + 9xf'(x) + 9y - 2yf'(x) = 0
f'(x) (2y - 9x) = 8x + 9y
f'(x) = (8x + 9y)/(2y - 9x)
