Expression for ground area is 5 - 4x²
Step-by-step explanation:
- Step 1: Find the ground area without the two pits.
Ground area = 5 - 2x²
Pit 1 area = 2x²
Pit 2 area = 4x²
⇒ Expression for the ground area without the two pits
= (5 - 2x²) - (2x² + 4x²)
= (5 - 2x²) - (6x²) = 5 - 2x² - 6x² = 5 - 4x²

A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes.
We know the formula , Distance = speed * time
Speed is constant and it is 12. So it is linear
The function becomes d = 12t, x is the t is the time and d is the distance
At the starting point, t=0 and distance d=0
End point , t=45 min = 0.75 hours and distance = 12 * 0.75 = 9
So domain (t) is {}
Range (d) is {}
Answer: c) -0.3
<u>Step-by-step explanation:</u>
Consider the left point as (x₁, y₁) and the right point as (x₂, y₂)
then (x₁, y₁) = (-6, -1) & (x₂, y₂) = (5, 1)
x₂ - x₁ = 5 - (-6) = 11
y₂ - y₁ = 1 - (-1) = 2
ratio of a:b = a/(a+b)
1 : 2 = 1/(1 + 2) = 1/3
x-coordinate: x₁ + ratio(x₂ - x₁) = -6 + (1/3) (11) = -7/3
y-coordinate: y₁ + ratio(y₂ - y₁) = -1 + (1/3) (2) = -1/3
False! The solution should be x>24
