Answer:
See below
Step-by-step explanation:
The formula for calculating percent is
% = (cost of item/total cost) × 100 %
% = (cost of item/1875) × 100 %
% = (cost of item/18.75) %
You can use the same formula to calculate the percent for each item in the budget. For example,
Housing: % = 420/18.75 = 22 %
You can do this for each budget item and get the table below.
Answer:
3x36
Step-by-step explanation:
Because he is getting 36 3 times so 3x36
By a Fourth grader
Answer:
range: {y: y ≥ 0} ⇒ h(x)
decreasing over(-∞ , 1) ⇒ h(x)
increasing over (-∞ , 0) ⇒ g(x)
range: {y: y ≤ 1} ⇒ g(x)
increasing over (1 , ∞) ⇒ h(x)
decreasing over(0 , ∞) ⇒ g(x)
Step-by-step explanation:
∵ h(x) = (x - 1)²
∴ Its vertex is (1 , 0)
∴ The parabola is opened upward
∴ The range: {y: y ≥ 0}
∴ It's decreasing over (-∞ , 1)
∴ It's increasing over (1 , ∞)
∵ g(x) = -(x - 1)(x + 1) = -(x² - 1) = -x² + 1
∴ Its vertex is (0 , 1)
∴ The parabola is opened downward
∴ The range: {y: y ≤ 1}
∴ It's increasing over (-∞ , 0)
∴ It's decreasing over (0 , ∞)
