Answer: Anna could buy 5 sweatshirts for $60.
Step-by-step explanation:
lets figure out the price of one sweatshirt.
45/3 = 15
one sweatshirt is $15
5*15=60
so 5 sweatshirts cost $60
Your answer is B. 0.9272. Hope I was able to help!
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 , ∞)
Answer:
AB =7 and CD = 7
BC =4 and AD =4
Step-by-step explanation:
A( 1,3)
B (1,10)
C (5,10)
D (5,3)
As we can see in the graph, the AB = CD and BC = AD
AB = the distance between the y points since the x values are the same
AB = 10-3 = 7
AB =7 and CD = 7
BC = the distance between the x points since the y values are the same
BC = 5-1 =4
BC =4 and AD =4
