Answer:
Jeremy's house is 4.5 inches far from his friend's house on the map
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The house of Jeremy's friend is 72 miles away from his home
∴ The actual distance between the two houses is 72 miles
∵ The scale on Jeremy's map is inch is equivalent to 8 miles
∴ Each miles on the map represents actual distance 8 miles
By using the ratio method
→ Map length : Actual length
→ inch : miles
→ : 8
→ x : 72
By using cross multiplication
∵ x × 8 = × 72
∴ 8 x = 36
- Divide both sides by 8
∴ x = 4.5
x represent the distance between the two houses on the map
Jeremy's house is 4.5 inches far from his friend's house on the map
When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.
0 = -(x-2)^2 + 16
(x-2)^2 = 16
x-2 = 16
x-2 = 4
x = 6
This means the ball will hit the ground 6 seconds after Amir threw it.
