Answer:
Step-by-step explanation:
Speed of the bee = 15 miles per hour.
Formula to represent the speed of the bee will be,
Speed = 
Distance = Speed × Time
Therefore, function representing the distance will be,
F(t) = s × t
Where t = time
s = speed
A). F(t) = 15t
B). If t = 20 minutes ≈
hours
F(t) = 15t
F(20) =
= 5 miles
C). If f(t) = 12 miles
F(t) = 15t
By substituting these values in the function,
12 = 15t
t =
= 0.8 hours ≈ 48 minutes
D. Use FOIL and guess and check to factor the equation
Answer:−6y+9.6z−3
Step-by-step explanation:−(6y−9.6z+3)
−6y+9.6z−3
The zeroes are
0, -5, 3 + i (and its conjugate)
The factors are
x (x + 5) (x - (3 + i)) (x - (3 - i))
Expanding...
(x² + 5x)((x - 3) - i) ((x - 3) + i)
(x² + 5x)((x - 3)² - i²)
(x² + 5x)(x² - 6x + 9 - (-1))
(x² + 5x)(x² - 6x + 10)
x⁴ - 6x³ + 10x² + 5x³ - 30x² + 50x
x⁴ - x³ - 20x² + 50x
