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
Answer:
y = -1/16 (x-3)^2 - 1: This is the vertex form
y = -1/16x^2 + 6/16x - 25/16: This is the standard form.

Answer:
70 dolls
Step-by-step explanation:
Hello!
The ratio is 5:2, which are division of a whole. They can be represented as 5x and 2x.
Jacky has 5x dolls, and Peter has 2x dolls. They were equal after subtracting 15 dolls from 5x and adding them to 2x.
Equation:
Solve:
- 5x - 15 = 2x + 15
- 5x - 30 = 2x
- 5x = 2x + 30
- 3x = 30
- x = 10
So Jacky has 5(10) dolls, or 50 dolls, and Peter has 2(10) or 20 dolls.
The total sum is 70 dolls.
