Answer:
C
Step-by-step explanation:
Since the figure is a square with all 4 sides equal, then calculate the length of EF and multiply by 4 for the perimeter.
Calculate EF using the distance formula
EF = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = E(0, 5) and (x₂, y₂ ) = F(5, 0)
EF =
=
= =
Hence
Perimeter = 4EF = 4 × ≈ 28.3 → C

Step-by-step explanation:
<h3><u>Given functions:</u></h3>- f(x) = 4x² - 6
- g(x) = x² - 4x - 8
Subtract both functions
(f-g)(x) = 4x² - 6 - (x² - 4x - 8)
(f-g)(x) = 4x² - 6 - x² + 4x - 8
Combine like terms
(f-g)(x) = 4x² - x² + 4x - 6 - 8
(f-g)(x) = 3x² + 4x - 14
After 14 weeks, both Megan and Conner will have saved the same amount.
Step-by-step explanation:
Amount Megan have = $50
Amount saved each week = $5.50
Amount Conner have = $18.50
Amount saved each week = $7.75
Let,
x be the number of weeks.
According to given statement;
M(x) = 50+5.50x Eqn 1
C(x) = 18.50+7.75x Eqn 2
For amount to be same;
Eqn 1 = Eqn 2
Dividing both sides by 2.25
After 14 weeks, both Megan and Conner will have saved the same amount.
